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. Hi Andrue. 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. The PID gives you consistency. MY GC does the same thing, the pump tone changes when the boiler is heating. have you had any issues with the k type or have heard of this? Whole Latte Love has a new video about preinfusion on the classic. Rancilio SilviaPID. the PWM needs a new wire to the where the pump wire was disconnected. Thanks so much for the awesome guide!

Also, the diagram of the controller lists SSR to connects to terminals 9 & 10. Hi Tom. P 53.1 Some people have done this by replacing the water filler funnel and 3D printing a replacement cover. You can use the same 18 gauge wire between the heating element and the SSR. 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. 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. The 12 volt wires from the SSR connect to terminals 4 and 5. Pull off the steam knob and disconnect the steam wand. The installation is completely reversible if you ever want to sell the machine or send it to service. My only concern is the diagramm I downloaded from whole latte love shows different connections then what I have seen in my unit Wear a glove when reaching in from below, otherwise bloodletting is likely. I am beginning to suspect that Gaggia created as many combinations of wiring configurations and colors as they made machines. I have read reports of measurements of up to 8 degrees C lower at the portafilter. The operation is the same as the unmodified Gaggia machine. This kit doesn't control the steam temperature nor has the pre-infusion function. Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. 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. $285.00. Users can also bypass the timer to use the switch on the machine for manually controlling the brewing process. I strongly suggest checking which switch terminal switches the mains. But that also seems fiddly. If your connection is down to just a few strands, that will generate heat. Hi Chris, I appreciate your tutorials on the PID install. My next thought was that the controller wasnt reading the correct temperature. I know what I will be trying tomorrow , Hi, For espresso, 9 bars is the generally preferred pressure. The pump is not wired in series with the Heating element so Im not sure what is causing this. This product was added to our catalog on Friday 12 August, 2011.

Display: Dual display for Fahrenheit(F) and Celsius(C) Thanks. 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. 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. I still have one question you may be able to answer. Gaggia Classic Coffee Machine Modelo 3D TurboSquid 1036412. This is the only concern left for me.
