Vaillant 824E providing hot water but no heat???
Hi
I have a Vaillant Ecomax 824E Boiler which has been working fine until 2 days ago. It's supplying us with all the hot water we ask it for, however, we have no heating. Although, the thermostat and radiators are asking for it. The boiler is showing no error code at all but stops on no 6 once reset.
Please help.
