In need of some advice. We have got a Vaillant Turbomax 824 boiler which was installed 20 years ago before we bought the house. At the last service in December the engineer cleaned the heat exchanger (hot water was not working very well) and pumped up the expansion vessel. A couple of days later we noticed that the pressure was going up by about one digit a day. Phoned the engineer who told us just to drain the water off (we must have touched and moved the filling valve). Since then he doesn't take calls or answers texts.
Tried to get a Vaillant eng. which is anything but easy. Contacted 3 who asked for the Model No. and fault code (no fault code as the CH and hot water work well). No more contact after giving details about the problem. Last week another Vaillant installer turned up, pumped up the expansion vessel and assured us that the problem was solved. 3 days later water pressure is rising again and the eng. ignores texts and calls.
We have just sold the house and obviously the boiler has to be working properly for the new owners. We are now thinking of contacting Vaillant for a fixed price repair. Why is it so difficult to find a competent engineer or is the problem too complex? We have always paid the bills promptly. Sorry this is a very rambling post but we are at our wits end.
Thanks in advance for any advice.
