Boiler issues
Former Community Member
We have a Potterton Combi boiler, it was losing pressure. Engineer replaced the diverter valve and said it was corroded. It worked fine for a few days before making a loud banging noise for s few minutes which stopped when the sink taps were on. It was ok for a couple of days and then went off completely. The engineer says the circuit board needs replacing but I'm wondering what caused the issue with the circuit board & whether it will just blow again. I think the boiler is about 8 years old. Any advice welcome.
Vaillant offers 10 years full warranty on boiler installs by their approved installers (parts and labour). Sounds good, and my one about 15 years still works fine and no problems to date. Probably blow up tomorrow though!
