This will be the one at the bottom of the boiler, closest to the group head. The Gaggia Classic has a max power consumption of more than 1400W, which can easily burn up a cheap SSR. Thanks in advance for any reply! I would be glad if you have any recommendations. You can verify the SSR by disconnecting its AC terminals and checking that it is indeed turning on and off. Otherwise, it all works properly now. More to explore . My install went as smooth as I hoped all my wire colours and locations were identical to yours (Phewf). 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. Thanks for your reply: I think you are correct about the Gc being stuck in steam mode, but I never touched the steam switchs wires and reverting the top/bottom swap on the power switch didnt solve the issue. Run this wire along the rest of the existing cables and out the back of the Classic, through one of the vent slots. Did you try with the SSR unit 40 DA or 40AA? If you do this, consider counter-sinking the magnet so that it is flush with the outisde of the box. It should work as a replacement for the C-100 and SSR, but because the SSR is built into the PID, so your wiring will be a bit different. Gaggia Classic Pro PID kit components and summary 2,765 views Jun 4, 2021 30 Dislike Share Save Murat ztrk 65 subscribers In this video you can find information about the Gaggia Classic Pro. I decided that for me, its not worth worrying about. Hi Paul. Hi Jun, glad you found this helpful. Hi Chris, I completed the whole project both for brewing for PID and steaming via alarm. I might even have the original box. The 103 is not a true 103, that is what is getting measured in the boiler wall, and there is also a temperature drop off between the boiler and the portafilter, so your final espresso temperature will be lower. And anything is going to be a huge improvement over the thermostat that the PID replaces. Some people have done this by replacing the water filler funnel and 3D printing a replacement cover. Please note that I'm only using the PID to control the brew temperature. under the name replacement PID kit parts with very low prices. Has a black power coat paint finish, done by the vendor or manufacturer. Thread the thermocouple wire through to the back of the machine, and out the same slot as was used for the other wires. Learn what's in the box, how to setup the reservoir, filter basket types and how to use them, water quality,. This wont be enough for the boiler heating element. Terrific write-up thank you for posting it! Thoughts & musings from a product developer and manager. Test that everything is working before closing the machine back up. Is it necessary to use a heat sink with the SSR installation? Likewise, you can use 22 awg for the connection between the PID and the SSR. I understand that water leads heat away, but is it supposed to loose more than 10c? Gaggia Classic Pro/2019 complete wires and controller PID kit - 1/32DIN. 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. This is the setup that I have assembled two days ago. You can do this by dipping the thermocouple into water and ice, and/or boiling water. You can buy them at Ace hardware for about twenty five cents each. The thermocouple that I ordered fit into the threaded adapter without any modifications. Unlike the 7200 model, this one does not have SSR inside. I print with PLA filament, which has a much lower melting temperature than the plastic that Lego uses. If you used piggyback connectors, it should be a quick job to move the right one over to the correct switch terminal. My next thought was that the controller wasnt reading the correct temperature. Remove the thermostat. It heats up to 93 +-1c and then goes down as soon as i hit the switch brew. This morning I pulled my first shot with the PID. Thanks in advance! Are you sure you want to create this branch? 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. Is there a way to calibrate the read out close to the water out temperature. I hope it helps some EU folks not spending extra hours on debugging this minor EU-US model difference . 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. Hi Jeff. The PID is really converting the mains voltage to 12VDC both for its internal operation and to drive the SSR, so the PIDs draw is quite small. Shades uses an XMT7100 modified to run two SSRs: a DA for the brew temp and an AA for the steam temp. Hi Evan. Hi Dennis. Always double-check your specific models wiring terminal layout and numbering scheme. The LED on the SSR is functioning but no current can be seen. YOU ALONE ARE RESPONSIBLE FOR YOUR OWN SAFETY, PLEASE KNOW YOUR LIMITS. im trying to find out from shades why shades uses 2. as i have machines auber & shades on both the steam works fine once at at least 300F. It will also be completely reversible and much cheaper than ready made solutions!This clip can also be treated as a how-to instructional video for anyone wishing to go the DIY way. I havent lowered brew pressure to 9 Bars yet so perhaps changing that would level out my pump pressures? https://www.amazon.com/gp/product/B00LODGP2E/ref=ppx_yo_dt_b_asin_image_o05_s00?ie=UTF8&psc=1, BOX Gaggiuino started as an idea to improve an already capable coffee machine while keeping the machine appearance and button functionality as close as possible to the original. There is no 12v anywhere in the GCP, its all mains power inside. Accuracy: 0.2% Please let us know if theres a way to show our gratitude if theres a charity or cause we can donate to for you putting this guide together. 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. What you describe is pretty normal, except that I am a bit surprised that your steam drops temperature down to 102. Maybe then try QB-T7100 afterwards and if it works I will buy the external case which is sold seperately (QB looks nicer with small size and external case). The same complexity applies to pressure control. Includes both BREW and STEAM control SSR's. Suitable for new style Gaggia Classic coffee machines usually made in 2018 or after. My problem is, unlike Rancilio Sylvia, heating element of Gaggia Classic Pro seems impossible to connect without cutting cables. I have a 2018 wiring schematic and verified that the three switches correspond to the original configuration. US based Gaggiuino tailored print service; International print shop . Then the PID will only switch on when the boiler temperature drops below the target temperature. The MCP9600 board is fastened with a screw to the small ledge inside the 3D printed box. Is this typical? Chris, this is a far simpler way to add preinfusion. 40A SSR Solid state relay included My Gaggia Classic Pro Controller (PID, flow control, brew profiles, and more!) Gaggia Classic OPV spring mod kit - Standard version (just springs) $12.78 Shades of Coffee Slim drip tray complete with long vent tube for Gaggia Classic $30.67 Shades of Coffee Bottomless Portafilter with walnut wooden handle (smooth) - for Gaggia Classic / Classic Pro $42.17 Shades of Coffee Again, as above, run this cable out the back, and leave it unterminated and longer than needed. Here are some pictures of the Lego enclosure: https://www.reddit.com/r/espresso/comments/owpfe7/i_made_a_lego_enclosure_for_rex_c100_pid/. To do this, loosen the nut connecting the steam wand to the steam control assembly. When set up on my bench it tucks away nicely in behind out of sight and only needs to come out when in use. Thermocouple: J,S,K,E,Wre3 ~ Wre25 Hi Chris, I appreciate your tutorials on the PID install. I dont own a multimeter. And once you start considering adding in a power supply, you might as well go for a PID. Nikola. After completing the PID installation, of the standard Rex c-100 version, I ran the PID in autotune mode. How to install a pid on the gaggia classic pro. There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. The OLED and buttons can be secured with your favorite adhesive. Free shipping. Gaggia Classic Pro PID Installation #5 - I have power! The Arduino board is secured using a small amount of hot glue. Your wiring looks right. After autotuning, my values are: Thanks a lot for the answer. 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. There are no holes in the printed parts for the wiring between the PID and espresso machine, you'll need to decide where you want these holes and drill them yourself. If your connection is down to just a few strands, that will generate heat. Thanks in advance, this was a huge help! Hey. It seems the wiring varies even within model years, and between model regions. If so, any idea how it can be achieved? Is P=620 maybe an overkill, as I havent seen such a big value at other places? The only other thing I can think of is the relay. Recently purchased and upgraded Gaggia Classic Pro from Whole Latte Love in late November, and built/installed the Gaggiuino mod myself in February. Heres a picture of the screws I used, with screwdriver for scale: Great article and development, congrats! Only needs 2 x AAA batteries. Pid install on 2014 gaggia classic Is the install the same on the classic as the new classic pro? This would explain the constant switching on and off. 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. i heard from some that the PT100 with the M4 is more accurate. great article !!!! At a minimum, I think you would need the following: I dont see piggyback connectors on Mr Shades list, maybe those are part of the set of wires, but its not clear. Most likely they will have the same connector types as the REX-C100, but its always possible that you will need different connectors depending on what you end up ordering. Im wondering if this could somehow be the outcome of a bad SSR: Im not seeing current flow between the two AC terminals of the SSR when the PID is attempting to heat the boiler to the Set Temp. Remove the cover assembly and filler funnel by unscrewing the two small screws at the rear of the top. Hello Chris, Do not over-tighten the adapter, it only needs to be finger-tight. Have had the parts sitting around for months and no time to install! The lid of the enclosure is held by four screws. It would be great to see how the machine is behaving without the PID, to get a baseline. The C-100 that I received was set up properly, I only had to change the temperature. I am beginning to suspect that Gaggia created as many combinations of wiring configurations and colors as they made machines. Im on [emailprotected] gaggia classic pro pid installation guideAUBER PID for gaggia classic proThis is a walkthrough / guide on ins. We have an earth leakage wiring system in our house, but in many countries, these are not standard. Hi Jimmy. Did you reverse any wires to the steam switch? The Rex c-100 reads in Celsius only, would I be able to substitute this kit with: 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. The sensor has three wires: 1 x red and 2 x white. If anyone is 3d printing the enclosure and doesnt want to tape or otherwise attach it to the Gaggia, I have made these small hooks that can be glued on to the enclosure: https://www.thingiverse.com/thing:4938828. On thing I realised is that Mr Shades does not allow purchasing the parts seperately unless you already purchased the kit as a whole. You wont need the heat sink, the GCs case does that job for you. Watching the steam temp with the PID is interesting (I know it has no effect on it, but it is cool to see how it reacts now) and it is definitely best practice to steam while its on its way up in temp, once it hits the set point it comes down for a while (mine settled around 130 before it started back up).
