Recently, a problem has developed with my Ideal icos HE18 boiler. There seems to be 2 things at play:
1) The boiler switches on seemingly randomly when there is no demand for water from the programmer. When this happens the "burner" light is lit or flashing and the pump next to the hot water cylinder is on.
2) Occasionally, a reasonably loud grinding/banging sound can be heard from the boiler which lasts about 20-30 seconds.
Although these problems exist, the boiler is supplying hot water.
I have a few questions regarding this:
1) What sort of problem could this be? Are there any simple fixes? If not, how expensive is this likely to be to fix?
2) I have no knowledge of boilers/plumbing. Any ideas of how to find a good engineer to fix this (other than randomly looking through yellow pages or googling)? Asked a few friends/family but haven't had much luck.
Thanks
