A friend of a friend of mine has a vaillant gas combi and it is just out of the 2yr warranty. He took out a BG service contract and the pressure keeps dropping on the gauge and he has to keep topping it up every day. He has had BG out 6 times and all they say is there is nothing wrong with it and to keep topping it up. He has put the fault codes on the internet and apparently there are loads of hits saying that the boiler thinks that there is a fault with the diverter valve even when there isnt. He is now faced with Vaillant coming out to do the job and will try to charge BG for the callout.
