When starting hot water or CH it appears to operate correctly but as the temp leds are rising the last one or 80deg lights on its own and the ignition switches off. accompanied by all the led's blinking for a short time
This is an intermittant fault
Dont know if this is a coincidence but if i twiddle the thermostat controls and turn them up slightly it seems to clear the fault and work ok
have i a faulty pcb or one of the sensors ?
