Hi, it seems quite a few of these Protherm boilers have a similar fault to mine so I hope someone can help me.
Boiler will run DHW and for no apparent reason cut out, particularly annoying half way through a shower. Also sometimes I'll turn it on and it just doesn't fire up at all.
Will show F1 error code but not always.
Have to turn it on and off again at the mains switch to get it to work, leaving it anywhere between 10 seconds and 10 mins or so.
Similar with the CH although this seems to give more F1 fault codes
than DHW.
Had it serviced regularly and spent a few quid trying to narrow down this problem so far with no joy. Had overheat thermistor replaced but still the same - I didn't want to rush straight in to a new PCB as I'd imagine these are expensive.
would be grateful of some advice
many thanks in advance

P.S. Boiler is 6 yrs old
