I have a Vaillant ecoTec 832 which was installed on 15th November 2016 and has been nothing but trouble.
Under warranty vaillant have been out 3 times to replace the diverter valve, the pump and today the circuit board.
There is a grinding noise still coming when you use hot water. The engineer said it was because there was too much inhibitor in the system. Is this possible? My installer seems to think it nonsense and just wanted another opinion.
For the record the system was power flushed 3 weeks before install and has a magna clean magnetic filter installed at the same time as the boiler install.
