PCB KEEPS CLICKING

[stupot69]

Hi all.I will try to give as much info as possible.

I have a WARMWORLD HE BOILER,when the timer comes on in the morning there is a clicking noise coming from inside the airing cupboard where the hot water cylinder and control panel for the system is located.
I have been told that this is the relay switch on the pcb board,is this correct? If so,could someone please tell me what options have i got?
The clicking is driving me crazy,especially when trying to sleep after a night shift!!!

Many thanks.

It sounds more likely to be a faulty motor valve.

You options are either to dry to diagnose and repair it yourself or to call a heating engineer.
