CRM3605 is using PID stock. No mod needed on the temperature sensor unlike some other machine which is using analog thermostat. You just need to pre heat the water tank to around 50 degree celcius so that the thermoblock have more headroom to stabilize the temperature during brewing. Another advantage is more powerful steam when steaming milk.
The only mod you need to do is the pump. If you unscrew the bottom, you will see the connection for the pump. You just need to unplug the wire from the circuit board to the pump, tap the pump to the 500w dimmer switch or solid state regulator. I'm using solid state regulator with 100k ohm potentiometer. When brewing, turn the knob almost to the minimum. As I'm using bottomless portafilter, the pre-infusion take around 10 seconds and will saturate the puck. Turn the knob to increase the flow while watching the pressure gauge. Once it reach 9 bar, stop there and continue to extract. You can play around with the pressure during brewing process. One of my favourite method is to slowly ramp down the pressure to around 6 bar before reaching my desire extraction weight.
PS: Ignore the red switch. Previously use the red switch to manually switch on the heater for old Poemia espresso machine. Not use in Gemilai. The potentiometer come with the solid state regulator resistance is too high and at minimum will stall the pump.

Would you be able to share with me the wiring diagram of this SSR? I see you shorted the SSR.
Thanks
