Hi,
Wonder if anyone can help.
I've had a job that I went too where the PCB was burn't out on a ARISTON MICROCOMBI 23 MFFI and not working. It was burn't underneath at the capacitor.
I've fitted a new pcb board (part number: 65100248) but now after fitting it the power light on boiler will not come on until I disconnect the terminal CN202 on the pcb board,
Now i've done some investigating and when you disconnect the domestic HW flow switch it the boiler then works.
It looks like the domestic HW flow switch has 3 wiring connections so question is is it just that, that is FAULTY or is it another component that is causing the pcb mains-on light not to light.
Question is is this also what caused the pcb to burn in the first place?
Anyone familiar with ariston boilers??
