Ive seen the steaming power on the classic remains solid from 125C and up, anything below that results in mediocre steaming power, which makes me wonder if I just have an aftermarket part that shouldnt be on this machine, or is just signs of imminent failure. Thermocouple: J,S,K,E,Wre3 ~ Wre25 Hi Chris, I am gathering / ordering the parts specified and was surprised to find out the price for 3d printing price spiked. . under the name replacement PID kit parts with very low prices. I hesitate to identify wires by their color, as the wire colors in the Gaggia seem to vary from year to year and from region to region. Maybe Im missing something? I am only using the Rex temporarily while working on a project with a Raspberry Pi (and the cost of the Rex was only a couple dollars when ordering the SSR), otherwise I would reprint the entire enclosure with the hooks built in. One end is connected to the mains connector at the back (where it is showing N sign), the other end is connected to the back of the on off switch (as you showed on the picture above). If nothing happens, download GitHub Desktop and try again. Fortunately, no damage done, and you can easily revert your changes. This is really a DIY project. auber pid kit gaggia classic. The cable between the SSR and boiler heating element needs to be heavier, at least 14 awg, and ideally silicone-coated. If your connection is down to just a few strands, that will generate heat. So far the temp range Ive seen when the heater cycles on/off (after ~30 mins of warming up) is ~90C to ~97C. Note: I fully tested the PID, SSR and thermocouple on the workbench before final installation. Does the PID generate enough heat to melt the Lego bricks? Due to your kind and quick advice, I could order SSR40DA. Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. Hello Chris, So 3 possible solutions: getting the main not from the switch but from the output of the timer board (probably nicest, but figuring out the right wire will take time) OR do the rocker switch mod (https://www.shadesofcoffee.co.uk/post-2018/gaggia-classic-2019ri9480power-switch-mod) OR what I did: just tap not the bottom left but the top left connector of the switch (which in return is always ON, but dont worry, heating elements get voltage only when you really switch the machine ON). To set the target temperature, press the Set button on the front of the panel. Hello, I am new to Gaggia world with my Classic Pro 2019 model and on the way of installing DIY PID for both brew and steam functions. I think Mr Shades has managed to do this using only cables because I dont think he instructs anything to void the warranty. I just finished installing the PID hardware in my Classic Pro today. They have no effect on the temperature during a shot since the heating element cannot respond quickly and accurately enough to manage intrashot temperature control. Perfect, came back here to ask this question! I can actually taste the sweetness for the first time. Thanks in advance, this was a huge help! This would also allow you to switch to PID-controlled brew mode simply by lowering the PID temperature. Thank you for making it. If you do this, consider counter-sinking the magnet so that it is flush with the outisde of the box. Did you make any changes to the setting of the PID? Do you think this makes difference? Also some pids come with a built in relay. Double sided tape will work. great article !!!! Hi, thanks for the articely, it was great help to do the initial steps. If you had to recommend a single display PID, which one would you steer me to? You can use the sensor reading on the PID display to know when to start steaming. Thanks in advance! I just started working as a barista. (for a reasonable fee of course). You can verify the SSR by disconnecting its AC terminals and checking that it is indeed turning on and off. did the REX-100 require most of the default setting to be changed or is it similar to changing like shades PID or Auber PID. 1 RELAY alarm: Normal open, capacity 250V/3A AC or 30V/3A DC Thanks. I have changed the default value of the SL parameter to work with the RTD sensor (K thermocouple was default). I will monitor it over the next few days, but if the coffee takes good, and the only thing I notice is the warmer cup tray, Ill be fine with that, better in fact! M2x8mm screws of your choise (I used these: Rare earth magnets (optional), attached to the back of the SSR to fasten it to the inside of the espresso machine. Sure enough, it powered up. If youre not comfortable installing this yourself, and taking on any followup maintenance, I think you would be much better off purchasing a machine that comes with a PID from the factory. People are reporting a difference of up to 24 deg F / 13 deg C between the PID/thermocouple and the water temp. The code is reasonably well commented internally and variables are named such that it should be easy to find values you may need to change for your specific implementation, such as which pins have buttons assigned to them or the output pin for the SSR. Note that my mod is to a Gaggia Classic, not a Gaggia Classic Pro. and its definately better than Auber which is NOT preinfustion by kicking off solenoid. Again, as above, run this cable out the back, and leave it unterminated and longer than needed. Im so thankful for this. i ordered K type and PT100 both for M4. Chris thank you so much. I used lamp cord for this. 3-Connect the other cable to the terminal on the on off switch, which is on top of or below the Live cable. I completed the installation last night and like you it too me about 5 hours But this included cutting a hole in the case stainless steel case to mount the PID controller internally, and that was probably the most time-consuming and difficult thing. Pressure control could be super nice to have. When the PID signals the SSR, as indicated by the brew ready light and the output led on the PID, the pressure coming out of the pump decreases, and then increases again after the PID out to the SSR turns off. Shades. The required parts are a PID controller, a solid state relay (SSR) preferably rated for 40 amps, a K-type thermocouple, a thermocouple adapter to connect the thermocouple to the Gaggia boiler, wire rated for mains voltages as well as some smaller gauge 12 volt wire, male and female quick disconnect connectors, spade connectors, and two piggyback spade connectors. Brilliant article. Thread in the M4 thermocouple adapter in the place of the thermostat. You should be able to find the switched mains with the help of a multimeter. Pull off the steam knob and disconnect the steam wand. The enclosures purpose is first to protect you from the mains current, and second, to make it easier to attach the PID to the Gaggia. Hi Murat. I also cleaned the part of the group head that that gasket sits in. You can use the same 18 gauge wire between the heating element and the SSR. You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. Approach 1: Follow my writeup, adapting it to your models peculiarities, and then set the PID temperature to your preferred steam temperature. I got the white plastic in one of the stock connectors a bit burned, the plastic looks brown in some areas and a bit melted. The sensor has three wires: 1 x red and 2 x white. Wire colors and positions seem to vary. You'll need the following parts, as well as basic soldering tools/skills and access to a 3D printer (if you choose to use the included .stl files). Hello, thanks for the nice and valuable text. I like the quality of the shots, and temperature consistency is more important to me than pressure consistency. if i understood not adding a steam will give better steam? This design is intended to be as simple as possible in terms of the installation, and requires minimal modification to the Gaggia machine. If you used piggyback connectors, it should be a quick job to move the right one over to the correct switch terminal. Can the PID be put inside the machine or does size constraints and/or heat negate that option? By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. I print with PLA filament, which has a much lower melting temperature than the plastic that Lego uses. . The boiler in the Gaggia can get hot enough to melt non-silicone insulation so if you don't have silicone wiring, make sure to keep any wiring well clear of the boiler. P, I, d, controlling period, digital filter coefficient, and more (for control theory experts only) Does anybody have a Shades of Coffee pdf for the brew and steam setup on the gaggia classic, mines a 1998 classic coffee model, it would be much appreciated. You could definitely drill out the adapter a bit to get the thermocouple to fit. Ive attached an album with my wiring below; Ive literally had an engineer look at it and The Gaggia is 100% at its original state except for the power taps on the neutral at the plug, the live on the brew switch, and the thermocouple to SSR wiring: https://imgur.com/a/rc4xtfz. Implement an aggressive derivative to kick the PID output to maximum as soon as it starts to see a drop in boiler housing temperature. 102 is even 3 degrees below my brew temperature. Hi Eddie. If you use anything different you'll need to make adjustments to the 3D printed parts. The .ino file includes several libraries. I have a 2005 GC with a Mr Shades PID kit installed. Tags Slim PID Holder for Gaggia Classic Design to 3D. I grabbed some screws from my parts bin, I took whatever I could find that was the same color as my filament, and that would fit the holes and hold reasonably well. however the one SSR is nice and the modification gives upgraded steam with the solder mod. The GC comes from the factory with a simple thermostat that turns on at a certain pre-set temperature, and turns off at another pre-set temperature. Perhaps Ill use a spare Arduino or FPGA to PWM the boiler while brewing as someone else was saying. You are right, its an M4 thread, not M3. I started with 103, and bumped it up to 105. Their kit is convenient, and is the way to go if someone doesnt feel ready to take on a 100% DIY project. Most thermocouple calibration articles that I have read use ice water to calibrate to zero degrees C because the boiling point of water varies with altitude. Followed the DIY guide for the xmt7100, highly recommend if you're looking to save money. The thermocouple that I ordered fit into the threaded adapter without any modifications. Regardless of which thermocouple you choose to use, you will also need to factor in an offset no matter what thermocouple you use, and this is really based on your tastes. The PID will be more or less bypassed when the steam switch is on, it will just stop trying to heat because the boiler will be over the PIDs target temperature. The included STL files assume you're using the exact same parts I am. This is the setup that I have assembled two days ago. Your Gaggia would be in steam mode by default, you would never have to switch on steam mode. Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. K type thermocouple, 0-500, 2m cable (6 feet). Approach 2: Divert from my writeup by installing the thermocouple so that it replaces the steam thermostat, and set the PID temperature to your preferred steam temperature. The PID will show the temperature, and be somewhat confused by its inability to reach its setpoint, however the PID is bypassed in the same way when the GCP is in steam mode. Although this is optional, it is difficult to access the power switch to tap power for the PID, and it is almost impossible to reach the thermostat without moving the boiler, and the boiler cant be moved unless the steam wand is removed. Tighten one end of your connector down to one of the solid state relays AC (~) terminals and plug the other end into one of the disconnected thermostat wires. There was a problem preparing your codespace, please try again. https://www.thingiverse.com/thing:4243840. Im assuming it should be fine as well to use 18 awg wire to wire the mains connections to the PID, and between the heating element and the SSR? Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut. When I put everything back together, my machine started shorting out and tripping the circuit breaker on . Shades uses an XMT7100 modified to run two SSRs: a DA for the brew temp and an AA for the steam temp. This is VERY important! As for you steam mode question, if you followed this guide for installing your PID, the PID will have no effect on the the steam temperatures or functions. You wont need the heat sink, the GCs case does that job for you. I can only find vids and instruction for the pro (does anyone have links for the older version?) The LED on the SSR is functioning but no current can be seen. You should see a strange number when the PID first powers on, then after about 3-5 seconds it should switch to the temperature reading from the thermocouple. Hi Gene. Thank you very much if you find the time to answer me . Either way, you are looking at a lot more complexity and cost. If the thermocouple wire is too long, coil it up inside the machine, well away from the boiler or any uninsulated connections, using zip ties to hold the coil in place. The SSR is only rated for 5 amps. The coffee water temperature in the boiler of a home espresso machine is originally controlled by a bi-metal thermostat, which causes a big temperature swing. This wont be enough for the boiler heating element. Hi Brian. QB-T7200 48*24mm Programmable Digital PID Temperature Controller with Built-in 5A Solid State Relay XMT7100 AC/DC85~260V. Hi Justin. I had no issues with the K type thermocouple. This design is intended to be as simple as possible in terms of the installation, and requires minimal modification to the Gaggia machine. Looking forward getting your thoughts and ideas Connect the +/- leads from the PID to the SSR input terminals, paying attention to the polarity as these are DC. Slip some heat shrink tubing over the thermocouple, and ideally dip the thermocouple tip in some thermal grease, then insert the thermocouple into the adapter. it is basically removing the main pump wire and re routing back to the PWM out. D 9. Hey Chris, QB-T7100 48*24mm Programmable Digital PID Temperature Controller AC/DC 85-250V If the wiring was done correctly, the PID should power up when the Classic is turned on. Input. Optionally, you can add some sleeving to the wires running between the Gaggia and the PID. You could simulate pre infusion by briefly running the pump. https://photos.app.goo.gl/Xp37S3o3y6bqqrEk8 By the way there are three options as 12V, 24V and 85-250V DC. Has a black power coat paint finish, done by the vendor or manufacturer. Please be sensible and install a grommet anyway! One thing I would really recommend when anyone installs a PID system into the Gaggia Classic is to install a rubber grommet where the cables exit the machine. Converting CUSIP-6, CUSIP-8 and CUSIP-9 to ISIN in PHP, How to automatically block WordPress bot spam without a plugin, which I ordered as an inexpensive kit with a thermocouple and a solid state relay, PID installation in Gaggia Classic causing shortcircuits ColorMag, https://wiki.wholelattelove.com/File:GAGGIA_CLASSIC_2019_Wiring_Schematic.pdf, https://www.youtube.com/watch?v=UETVv0qgz-w, https://coffeeforums.co.uk/topic/53319-what-temp-offset-are-you-using-with-your-pid/, https://diy.stackexchange.com/questions/195229/in-a-light-switch-how-can-i-tell-if-the-black-wire-is-really-hot-and-the-white, https://www.reddit.com/r/espresso/comments/owpfe7/i_made_a_lego_enclosure_for_rex_c100_pid/, https://www.amazon.com/gp/product/B00LODGP2E/ref=ppx_yo_dt_b_asin_image_o05_s00?ie=UTF8&psc=1, https://www.thingiverse.com/thing:4243840, https://www.thingiverse.com/thing:4938828, https://www.reddit.com/r/gaggiaclassic/comments/l5tfcj/mr_shades_pid_installed_decided_to_mount_inside, https://calbryant.uk/blog/well-integrated-pid-temperature-control-of-a-gaggia-classic-espresso-machine/#better-temperature-regulation, https://www.vertex-qis.co.uk/Manuals/PT100_con.pdf, https://photos.app.goo.gl/8yPwJcEPDi1c5tfY7, https://photos.app.goo.gl/Xp37S3o3y6bqqrEk8, https://www.shadesofcoffee.co.uk/post-2018/gaggia-classic-2019ri9480power-switch-mod, Barista Tools that are Worth their Weight in Gold. I agree, the PID is a gamechanger. This morning I pulled my first shot with the PID. Im sorry about that, Eric. Ive been having trouble steaming milk lately, and wonder if there might be something wrong with the thermostat in my machine, wiring problems extending to this as well, or the steam valve might finally be needing a replacement. Let me know your thoughts !!! Comes with all of the accessories that originally came in the box. The two mains wires connect to terminals 1 and 2 (starting counter-clockwise from top-left). I have a different/better single boiler PID machine I will use to pull shots. This way you are not losing any pressure via the solenoid valve, you are just reducing the initial pressure to the puck by venting some of it through the steam wand. My P value is quite a lot different than yours. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. I used P:2,4 I:40 D:10 and Souf:0.2 which gives a shot stability around 2 degrees for single, 4 degrees for double shots. What is your coffee bean dark or light? I am glad this article helped. In mine, correct terminal was crosswise of yours. My ECM Giotto "Phoenix" Restored by the Coffee Machinist in Melbourne, Australia. Hi guys! Even with a perfect offset, you would also need to also take into account the temperature offset between the boiler and the portafilter. What you describe looks very much like the steam thermostat cycle. To be clear, a PID can increases the likelihood of a consistent starting temperature. . Its not a sensor, it doesnt send any information, it just switches on an off, at setpoints that you cant adjust. I found that moving the boiler up and to the side allowed me to get to the thermostat from the bottom really easily vs. the top. All other variables aside, once you get a temperature that gives you the results you want, you will be able to get those results again, and again. Also really awesome write up. The MCP9600 board is fastened with a screw to the small ledge inside the 3D printed box. Thanks. Please Whole Latte Love has a new video about preinfusion on the classic. Hey Chris, ESP32 IO. Have you got any ideas what might be going on? There is no 12v anywhere in the GCP, its all mains power inside. The thermostat is a replacement, the original one burned around three years ago. Apologies for the long questions, thanks in advance! Set the cover and screws aside. The C-100 can accommodate only one sensor/SSR, so you would only set it for brew temperature. have you had any issues with the k type or have heard of this? Im thinking Id like to start with just a temperature indicator, to assist with the surfing. I still have one question you may be able to answer. Because there is very little information on how to install a PID on the latest generation of the New Classic (2018 and newer, also called the Gaggia Classic Pro in North America), here are instructions on to do this. This approach would make your machine a bit weird to someone who wasnt aware of what you did, as the brew function would be completely unusable without adjusting the temperature. At the amperages required to control the boiler heating element, you need an SSR that has enough mass and exposed metal to be able to attach it to a heat sink. Universal Input: Thermo Resistor: PT100, Cu50 . However, at the cost of convenience, these kits can be relatively expensive. I have found the exact PID unit which Mr Shades is using and purchased it beside the Rex C100 kit you mentioned above: It would be great to see how the machine is behaving without the PID, to get a baseline. Other than that mine was a fairly straightforward procedure with no trouble at all. Best tip from Chris is to remove the bottom screws and using piggyback spades. I am glad you solved the problem, Murat. And anything is going to be a huge improvement over the thermostat that the PID replaces. Otherwise, it all works properly now. It heats up to 93 +-1c and then goes down as soon as i hit the switch brew. Take your time, think it through, and be patient. Coffee Sensor Gaggia Classic or Pro Tray and grids. The PID kit you described should work, but like the C-100 kit the I used, the included thermocouple wont fit in the Gaggia Classic. The C-100 will fit in vertically, with the screen facing up. Ive set the Sn value to pt for the PT100. I placed the SSR toward the left side of the back panel if facing the front of the machine. 342. https://photos.app.goo.gl/8yPwJcEPDi1c5tfY7 I am not surprised, Mr Shades runs an honest business, and those parts are being offered at low prices. YOU ALONE ARE RESPONSIBLE FOR YOUR OWN SAFETY, PLEASE KNOW YOUR LIMITS. As for steam, the guide I wrote leaves the steam function completely untouched. The only way to cut it is to unplug the machine. Check for wire that might have been too aggressively stripped, where some of the conductor might have also been cut away. Remove this thermal switch and replace it with the M4 thermocouple, making sure to add thermal compound if necessary. Are you sure you want to create this branch? Look at Gaggia classic PID install instructions. AC CIRCUITS ARE DANGEROUS AND MISTAKES CAN CAUSE INJURY OR DEATH. Shades. When I started steaming at that point thermostat never shut down the boiler because temperature did not reach to limit of thermostat. I bought the same parts as you have reccomended in the article but have run into the issue that the thermocouple is too large to fit into the adapter (theyre approx the same OD). you could use this guide on another kit as all of the pieces here are required for just about any pid. This PID-SSR combination does away with the 12v connection, and uses three wires for the mains power and SSR, with one wire shared between mains and the SSR output. I agree the ability to know exactly where the steam cycle is at is a nice convenience. Here are a couple of examples: Hi Chris, Do you know how to do this? From the factory, the GC has two thermostats, one for brew, which the thermocouple + PID + SSR replaces, and one for steam, which stays untouched. (PID Temperature Controller Meter Indicator, Jaybva Digital Universal Thermostat C and Fahrenhe F Display SSR and Alarm Output 40A Solid State Relay and Thermocouple Probe Heat Sink Included)? Do you have any diagram of the wiringi cant understand how to switch on the steam circuit so the second SSR would not try to heat the boiler in parallel. Is this just a matter of adjusting the offset of the PID? the PWM needs a new wire to the where the pump wire was disconnected. Im tempted to return the GC because I never used it prior to the mod and it may have been a pre-existing issue. Just leave the SSR disconnected, or dont install it at all. that will make it where only one SSR is needed. So I say go for it, but as Chris said, if you really dont feel comfortable with it, pass on the PID or try to find someone who can install it for you. Leave this cable longer than needed for now, it will be trimmed and terminated later. Likewise, you can use 22 awg for the connection between the PID and the SSR. Print services. (Markings can be found on front side of the plug) 2-Check the color of the cable which shows L sign on the plug- meaning Live. My plan is to install the Rex C100 first using your instructions. Maybe this will help? For espresso, 9 bars is the generally preferred pressure. If in doubt, sit it out, and get some help. It is a really tight fit to get the REX C-100 PID inside the machine. If you have never done this before, know that you are working with live household current, and this can kill you. I love the Lego enclosure idea. Ive followed these instructions and installed the mod using the REX-C100, SSR, K-type thermocouple and brass adapter linked in Chris excellent writeup (Thank you Chris). Everything else (Auber and Mr Shades) includes an M4 thread on their pt100. I would be glad if you have any recommendations. Thanks! Hi Jun, and thanks for the update. It would be almost impossible for me to give you a complete list of the parts from Mr Shades that you will need, as it will depend on the PID and SSR models you order. About 60cm of SiHF 2x0,5mm2 cable connecting the PID do the SSR 2. You need at least 20 amps. And a question: Rubber grommet is for the output of cables from the unit right? Works on both US 110V and EU 220V machines.Parts existing in the video:LED light kit: https://coffee-sensor.com/product/gaggia-classic-or-pro-water-tank-led-. i heard from some that the PT100 with the M4 is more accurate. Ill be using a xmt7100 (modified) for two SRRs and also tweaked for 12v out for led mod any help would be appreciated. Hello, A couple of zip ties come in handy here. Hi Chris. I cant see how this wouldnt be a thermostat problem, unless you somehow wired the steam thermostat into the PID, but you would have gone way beyond this walkthrough to do that. You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. The microfoam created by the commercial steam wand is tight enough for high quality latte art. Is 103 degree Celsius the best target temperature fit the PID? Screen Enclosure; Internal Component Housing; Additional Gaggiuino models can be found in the Gaggiuino Model Collection or on Discord in the #mod-3d-design-ideas channel. Wanted to double check here for some observations a about three months after installing the PID. This is because the switch is connecting the terminals vertically when it is turned on. Hi Eddie. I would re-crimp any connections that look suspicious. The only suprise for me has been that installing steam kit did not help me much because brewing kit alone helped to have great steaming power by only watching temperature climb up to 150 degrees. Chris, i read some comments here about steam. One bit of note and a request. Gaggia Stainless Steel 2 Cup Filter Basket with Pin Pressurised Crema 21000491. The PID has been setup with values for Kp, Ki and Kd that work adequately but you may want to adjust them to suit your needs. Rotary encoder + built-in push button; MAX31865 (SPI) Steam button; Brew button; Output. The REX-C100 should work out of the box, set for heating mode, with alarms disabled, and units set to Celsius. Its pretty straightforward. Nevertheless, I will take a look and see what values my controller is set to. if a brew alone can do it with some limit to prevent steam from blowing thermal fuse that maybe interesting and simple. https://wiki.wholelattelove.com/File:GAGGIA_CLASSIC_2019_Wiring_Schematic.pdf Mechanical Rocker Switches Tags Wheel For Containers and Boxes 3D model 3D printa. Using pliers to pull the connectors can pinch them on even more tightly, making them extremely difficult to remove. Gaggia Classic'teki stma sistemi basit mekanik termostatla altndan scaklk 85-105 derece arasnda gidip geliyor ve siz demlemenin hangi scaklkta balayp hangi scaklkta bittiini bilemiyorsunuz. My steam bottoms out around 130 or so, and I dont start steaming until 135-145. Is this a typo on your part or a mistake on their part? For the Gaggia Classic, taking into account the temperature drop between the boiler and the group head (5-8 degrees C), the PID target temperature should be set to about 103 degrees C or 220 degrees F at sea level. Feb 12, 2021. Complete with dual 250W cartridge heating elements (up to temp in ~8mins), bead-blasted stainless steel and internally a hammertone blue powder coat. Despite the K02 indicating K-type, it was advertised as supporting multiple types including PT100. robert kujawa 348 subscribers Subscribe 85K views 1 year ago In this video I'll install a PID unit on my. And once you start considering adding in a power supply, you might as well go for a PID. The thermocouple connects to terminals 6 and 7. Also, the diagram of the controller lists SSR to connects to terminals 9 & 10. Gaggia Classic Pro - Gaggia North America Commercial Steam Wand The commercial style steam wand comes equipped with a two-hole tip to perfectly craft velvety microfoam for lattes, cappuccinos, and more. Its not elegant, but does the job to give you a pretty good relative temperature to aid your temp surfing. I was initially concerned about my wiring (and my GFI) but its reassuring to hear you have the same side effects. Gaggia classic pro PID question. I currently have a Gaggia Classic (non-PID mod) and a Eureka Mignon Crono w/ espresso burrs. The C100 is probably made by dozens of different manufacturers. Re-attach the boiler with the four bolts, re-attach the steam wand, push on the steam knob, and put the lid assembly back on, without forgetting to re-connect the two ground wires. Hi Jimmy. I will purchase the PID kit with thermocouple and SSR from aliexpress and buy these rest small items from Mr. Your wiring looks right. Thanks for your time. Based on several comments, the wiring varies between units, even though they are the same model. Because the PID runs on mains voltages, an enclosure is required. Heat the shrink tubing. I have to turn the set point on the PID down to about 85C to stop it boiling and getting steam and a great deal of sputter out of the portafilter. About 60cm of 1mm2 (17AWG) cable to deliver power from the Gaggia to the PID 3. It should be the power/mains line that comes out of the main power switch, but before the boiler. Most assembly guides recommend using some thermal paste between the SSR and the Classic to ensure that any heat from the SSR is dumped to the chassis. The documentation showed the default settings as P:30 I:240 D:60, but after tuning they were P:37 I:50 D:12. Hi Nish.
