My theory at the moment would be that due to the PID control the heater is sometimes on at higher temperatures. Autotuning had resulted in shot instability up to 10 degrees during a shot probably because conditions during standby and during brewing are very different than each other. In this video I'll install a PID unit on my Gaggia Classic Pro. Make sure that all the new and repositioned wires are cleanly routed away from the boiler and pump and any uninsulated connectors. Hi Chris, Ive followed these instructions exactly (thank you for your thoroughness) except for how the mains were tapped: I moved the two wires terminating on the bottom of the power switch to the top, and tapped them (as per another guide). https://www.vertex-qis.co.uk/Manuals/PT100_con.pdf. The LED on the SSR is functioning but no current can be seen. A couple of zip ties come in handy here. The sensor has three wires: 1 x red and 2 x white. I have an old Gaggia Carezza (uses the Gaggia / SaecoEF0030/A Boiler). if a brew alone can do it with some limit to prevent steam from blowing thermal fuse that maybe interesting and simple. 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. Remove the thermostat. My only concern is the diagramm I downloaded from whole latte love shows different connections then what I have seen in my unit This gives the machine a whole new level of consistency, and gives you fine control over brew temperature. That controller is an interesting find. I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. Cup rest Gaggia Classic/Pro portafilter from stainless steel. Gaggia Classic Mods PID kits, OPV kits, and other mod kits designed for various Gaggia espresso machines - drill down into kits relevant to your model of machine. Please I have read reports of measurements of up to 8 degrees C lower at the portafilter. Keep the thermostat, in case you want to return the Classic back to factory condition. 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? gaggia classic pro pid installation guideAUBER PID for gaggia classic proThis is a walkthrough / guide on installing an Auber pid on the gaggia classic pro. I hope you enjoy your upgraded GC as much as I do mine! The lid of the enclosure is held by four screws. i ordered K type and PT100 both for M4. I managed to succeed on brewing side with DA SSR however I could not find an appropriate diagramm for adding my AA SSR for steaming alarm function. I would like to use it for steaming ONLY. Hi Murat, best part it is inexpensive and as easy as OPV mod, here are the links: 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. Hello Chris, Once you are able use the PID temperature readout to determine exactly what the steam cycle is, you know when to start steaming for more or less endless steam. 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). K type thermocouple, 0-500, 2m cable (6 feet). Please be sensible and install a grommet anyway! The Rex c-100 reads in Celsius only, would I be able to substitute this kit with: 1 / 9. 295.00 . When I turn off, it goes back to zero. 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. As seen on https://www.reddit.com/r/gaggiaclassic/comments/kmm09a/diy_pid_for_my_gaggia_classic/. Sure enough, it powered up. This guide should generally also apply to the 2013 GC, but you must assume that any of the switch wiring that I describe will be different for your model year. There is definitely a falloff from the temperature reported by the thermocouple at the boiler and what you will measure at the group head. You can use the same 18 gauge wire between the heating element and the SSR. Only needs 2 x AAA batteries. On top of the original price tag, international shipping, taxes, duties and currency exchanges can make obtaining these kits time consuming and even more expensive. Is there a way to calibrate the read out close to the water out temperature. The default target temperature on the PID will almost certainly not be correct. Even if that is the case, i dont have a clue as to why i would be in steam mode, since i didnt touch the steam mode button or its wires, i have already reverted my swap of the power switches wires (just from up to down on the same switch so that shouldnt have impacted anything) and ive validated that the rollback was correct with a multimeter. Please make sure you've downloaded them prior to uploading the code to your Arduino of choice. If you have never done this before, know that you are working with live household current, and this can kill you. Also, the PID generates almost no heat, because the work is done by the SSR, and this is heat-sinked to the Gaggia. Marca: Gaggia: Capacidad: 72 Onzas: Color: Acero inoxidable cepillado: Dimensiones del producto: Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. This is the only concern left for me. Brass is soft and easy to drill, and all the adapter needs to do is provide a connection between the thermocouple and the boiler, so there would be no hard in doing this. Since I cant control that, if you want to use it, you will have to parse the data: each line, after the headings, should start with the PID parameter (P, I, D) followed by the reaction of the controller. Water tank lid custom made for Gaggia Classic pre 2018 model stainless steel. Chris, i read some comments here about steam. The connector is on the back of the machine, where mains power is tapped with a piggyback connector and goes to the PID. An important part is that no internal cables/connectors were modified; all the connections were made by creating splitters using the purchased spade connectors. Curtis LMWDP #551 "Taste every shot before adding milk!" Henry_k #5 : by Henry_k February 10th, 2021, 12:35 pm I see no advantage of controling steam temp by PID - if it is 145C or 140C - not a big deal. I strongly suggest checking which switch terminal switches the mains. New - Gaggia Classic Pro/2019 PID kit - 1/32DIN single display $139.33 excluding VAT View Product Information Select Your Mounting option Silver case Black case TopBox with logo TopBox with gauge hole Stock situation: Silver case : Less than ten left Black case : Last one or two!!! Gaggia RI9380/46 Classic Pro - Mquina de expreso, slida, acero inoxidable cepillado . The best way to find is: 1-Connect one cable to the mains connector at the back where it is showing N sign meaning Neutral. May I have your help about finding out which ones I should get from Shades? Hi Kez. Hello. How do I ensure that Im tapping the neutral mains? r . Then the PID will only switch on when the boiler temperature drops below the target temperature. Tags Gaggia Classic Pro Tool Holster. Is 103 degree Celsius the best target temperature fit the PID? Hi Chris, 102 is even 3 degrees below my brew temperature. I still have one question you may be able to answer. I had no issues with the K type thermocouple. Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything. Pull the steam wand up and out of the Classic, and set it aside. 342. Hey Chris, The Gaggia Classic is a very capable espresso machine that gets even better with a couple of improvements. Do you think this makes a difference? 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. Glad this writeup helped. Trim, terminate and connect the wires you routed out the back of the Classic to the PID. Measured everything with multimeter, then realized that C100 doesnt get main while machine is on based on the lights. You are right, its an M4 thread, not M3. Apart from that, when I turn on steam mode, the thermostat takes temperature in the machine around 151c-152c, it doesnt turn on again after it goes down to 102C, then turns on and repeats the cycle. To do that I turned the machine upside-down. link to the pid I purchasedhttps://www.auberins.com/index.php?main_page=product_info\u0026products_id=232#espresso #coffee #latteart #lattemy current espresso bar setupLelit BiancaIMS nano coated filter basket https://amzn.to/3dyQgZyLibra coffee scale https://amzn.to/3ps114i Tamper distributor https://amzn.to/2Q0rk52Under Cabinet stick on smart light strip https://amzn.to/2SK6cBTSmart plug (homekit, google home, Alexa) https://amzn.to/2TTwUb4Fellow Espresso Cups https://amzn.to/3zN6Izmcappuccino cups https://amzn.to/3zMU1VxGaggia classic pro setupV V V V V V V V Gaggia Classic Pro https://amzn.to/39B5coTIMS nano coated filter basket https://amzn.to/3dyQgZyTamper distributor https://amzn.to/2Q0rk52Libra coffee scale https://amzn.to/3ps114iBarista Express setupv v v v v v v v v v v v v v Breville Barista Express https://amzn.to/2FQS9E4Libra coffee scale https://amzn.to/3ps114iTamper / distributer https://amzn.to/2HmhshGBottomless portafilter https://amzn.to/3jd52prThe bottomless portafilter says 3month delivery I got mine in two weeksDosing funnel https://amzn.to/35fcqM1Knock box https://amzn.to/2KFfESEitems not to buy based on my reviews:Delonghi La Specialista Dark Horse Coffee dark roastKeurigChapters:00:00 intro00:30 opening the machine01:05 removing the boiler (optional)02:13 removing/replacing the thermostat04:39 mounting the ss relay06:48 wiring the relay10:37 wiring the pid controller 14:16 mounting the pid controller14:49 mounting the boiler back on15:11 closing the machineAFFILIATE DISCLOSURE:Some of the links used in the description will direct you to Amazon, as an Amazon Associate I earn from qualifying purchases at no additional cost to you. Thanks again for the write up, Ill be playing around with temperature for the next week! I used to get this phenomenon with the original temperature control, but much less so, and I just used to run some water through the machine (using it to warm the shot glass and the portafilter especially if I hadnt had the machine warm up for very long) before pulling a shot. Nevertheless, I will take a look and see what values my controller is set to. PID, Auto Shot Timer Add to Watch list. and our These set the parameters and algorithms that monitor and control. Is it possible to do this with the GC factory temp sensor? My P value is quite a lot different than yours. Because the PID runs on mains voltages, an enclosure is required. Hello, there is another model without SSR built in with name 7100 instead of 7200. Depending on the draw of the display (I saw 50mA somewhere), you could also try running it off a battery. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. Heres a picture of the screws I used, with screwdriver for scale: Great article and development, congrats! Possibly not the optimal position but was really easy to install and I knew Id only be getting a relative indicative temperature anyway. About 60cm of FLRY 1.5mm2 cable to connect the SSR to the Gaggia4. Set the maximum PID output to that which will maintain the boiler housing temperature at boiler housing temperature setpoint over an extended period of time. I had no problem with my mod other than the stickers on the back of the PID were reversed, so the terminal markings were not correct. Cross referencing with the with the manual confirmed that the stickers had been reversed. Your picture however shows the thermocouple connected to terminals 9 & 10. add to list. I know what I will be trying tomorrow , Hi, Unfortunately, I didnt measure any temperatures for the un-modified machine. Coffee Sensor Gaggia Classic or Pro Tray and grids. The SSR is only rated for 5 amps. Specifications : Ring crimp connectors that fit the SSR need to be for M3 bolt, here's an example: https://amzn.to/3xcWBCq5. i heard from some that the PT100 with the M4 is more accurate. Realized with your last comment you dont have the offset in place, my bad. I double checked all the wiring (inside and outside of the chassis) and eventually came to the conclusion that I had a faulty PID. Hard to say how long it took because I was doing other things as well (dimmer switch, boiler pressure gauge, boiler rebuild, etc.) $15.59. I do not want to risk damaging my machine because of this. However I now need to connect steaming and brewing circuits in parallel rather than serial because steaming circuit will not be closed unless I turn on steaming switch and supply power to steaming SSR.
