Hey all
We have a new vallient boiler, which was installed in September. Recently when it's firing up or down it makes a series of clicking noises (sounds like it might be trying to ignite). It does this for ages. Then again when cooling down. It's only started doing this recently.
Anyone know what this might be? When I goggle it talked about limescale build up, but I can't see that being the case when it's so new.
