I have the above system boiler and have recently noticed a rapid, quiet "ticking" noise which seems to be coming from the PCB / user control panel area.
It's only noticeable when the utility room is otherwise silent and continues whether there's a call for heat or not. It stops immediately on disconnecting the power.
Otherwise the boiler performs exactly as it should.
Can anybody help me identify / address this noise?
