Worcester CDi Boiler No Power

Hello,

My seven years old Worcester CDi boiler is not firing up since morning even timer is not working. Can someone please diagnose that what is the reason behind no power to the boiler?

Thanks

James

Hi James

Hello James, if you are getting no power to timer, boiler, and thermostat then check these things:

Fuse Blown: If there is a flow of power, then fuse has probably blown & this can cause the boiler to have no power. Power will never turn on successfully without a running fuse. You have to change the fuse in order to get the power.
PCB Failure: Another common reason can be a PCB boiler as it communicates with some other parts of the boiler to keep the boiler working.
RCD Tripped: You have to check the RCD. If it has tripped than your boiler will not get power. Sometimes RCD tripped in poor weather conditions and after the power cut.

After fixing the problem, reset your boiler to get the power.
