Thank you LeeC Your right, I haven't got a clue, that's why I'm asking so please don't be sarcastic Dan Robinson, I don't suppose you know anything about my job. I'll phone a nice plumber, don't worry.
Hi, my Vaillant combi boiler sometimes (not always) doesn't fire up and produce hot water but, if I turn it off and on again it works. do I need a part or new boiler please ?
I'm glad I'm not the only one !! it's my first question and it's asking me for up to 5 participants :( how do I know who to put?? not sure I've done it right.
