potterton suprima 100 locking out

kered · 20 Oct 2005

have just had at great expense a new pump and then 3 way valve replaced. 2 days later boiler locks out. any suggestions, apart from shooting it? I had the pcb replaced about 3-4 years ago.

It could be the boiler pcb failed again!

Why dont you get a CORGI engineer to diagnose the fault for you?

I'd put my money on new pcb needed !!!! but try electrode lead and thermistor first as they are nice and cheap

What about a bit of residual air floating around the system and finding its way to the pump etc and causing the boiler to overheat?...cheaper still just to make sure it is all bled.
