Hi I have a Glow Worm Ultracom 30 cxi that has started making a noise when running, for hot water and heating. The noise is like a ticking scraping noise similar to a fan making contact with something.
I don't think it's the fan as it's definately coming from the water pump area, but I didn't think the water pump would run when demand for hot water. The noise continues on overrun until the boiler switches off.
Is there a common problem that this could be. Just trying to diagnose problem prior to getting an engineer in incase it's something silly.
Cheers
