My parents have a Vaillant Ecomax condensing combi-boiler.
It is at least 4 years old.
It has recently developed a fault I would like some help on.
The central heating works fine, but when hot water is called for the boiler stops working. The display shows no fault code, only the temp as usual, but is flashing. The only way to get the boiler to reset is to switch it off at the power supply for 2 or 3 minutes then it turn back on again.
Has anybody got any ideas as to what is causing this problem?
Thanks
