Biasi boiler making clicking noises

TAF

Hi

My Biasi boiler is making constant clicking noises and the hot water comes out hot cold hot cold.... the central heating seems to work fine, it even makes the clicking stop... but with the boiler is idle or on on water it makes the clicking noise

Anyone have any idea what this can be??

At a guess it sounds like your pilot light has gone out and it is failing to light?

Is it an automatic "spark" or one that is always on?

Either that or it could be a sticking gas solenoid or similar.

Needs someone who knows the boiler to have a look at it.
What does the destructions say in the fault finding guide?

The heating works fine... pilot light comes on so i dont think its that
