My GW 30 CXI has suddenly become much noisier. It is a mechanical noise present whenever the boiler is running. Sounds like the pump or fan worn.
My questions are;
1) How can I pinpoint whether it is the fan or pump?
2) Presumably if it's the pump, it's DIYable, but if it's the fan am I allowed to touch this?
Many thanks.
