Hi
sorry if this Q has been posted before - I have looked, honest
Both my CH pump and boiler emit a large buzzing sound which lasts for some time and usually occurs just after the system is turned off and the pump stops running. In the boiler the buzz comes from the sealed area which houses the pcb. The system turns on Ok and when it does the buzzing stops.
The pump is a BG Grundig and the boiler a Micron Glow Worm
Is it the pump or the boiler pcb that is at fault here and is it likely to damage the other component?
cheers
Geoff
