Hello, my name is***** be patient whilst awaiting any responses as I'm not constantly available.Most electrical problems can be serviced, but the cost is normally the prohibitive factor.. The irreversible electronic system malfunction is usually that the main PCB has been damaged... PCBs are usually a costly part and together with the labour charge the cost usually exceeds £300.. The question is really, do you wish to spend that amount on a boiler of that age, and are the parts still available
Do you know the exact model of the boiler as both boilers have different parts?
I couldn't see where the exact model number was on the boiler so I was just going from the instruction manual. I have now found phone number of the person who fitted it so he will come and look at it tomorrow so I will see what he thinks is best as to whether it is worth repairing. Thanks
