Ferroli HE 31c F37

[logjam32]

Hi everyone, I've recently replaced the pcb on my ferroli he31c boiler and its since come up with an F37 code (system pressure switch). The thing is when I put my old pcb back in it goes through its sequences etc and although doesnt ignite no error comes up. I've been having problems with relays on the board hence me changing it. Can you tell me if its a pcb parameter setting that needs to be changed so it recognizes the switch. If so do you have any ideas which setting needs to be changed.


Many thanks in advance for your help regarding this

Hi guys, no the boiler doesnt fire up at all. It just goes straight to F37. Not gsr, am electrician and thoguht it'd be a simple enough process changing the board. Thought It'd just be a parameter needing changing for it to recognise the low flow switch. Be greatful for any guidance.

Check boiler pressure is slightly above 1.5 bar to be sure, failing that you will need a gse

Thanks southcoastboile, have checked the pressure, thats ok. Will wait till get paid and get a gsr on it. They quoted £75 call out fee.

Thanks anyway for taking the time to respond guys, much appreciated.
