sounds more like dodgy pcb to me part number is 407677
part number is 407677thanks for reply noticed with it just on hot water its heating the rads aswell is that the same fault
Potty only work 8-5, we work round the clock! Its 0122 now.
Your boiler is a simple little thing that just provides heated water.
Your control system uses that water to heat the rads, heat the water cylinder or both.
It sounds as if its a problem with your control system and the boiler itself is OK!
