Hello forum,
I Have a Vaillant Ecomax 828 2e which has decided to play up over the holiday period. At present the DHW is luke warm at best. It takes ages for it to reach luke warm. The rads dont appears to warm up when DHW is on. The HEX gets hot very quickly but hot water takes it time to warm up. I have read through the other posts and checked the NTC thermistors and they are all within tolerance.
Readings taken from Diagnostic menu are as follows:
D35 1
D40 71
D41 56
D60 52
I believe that the HEX needs replacing. I have another question regarding the diverter valve stepa motor is very noisy. The noise is transferred into the pipework and can be heard through out the house. Any advise help would be greatly appreciated. Thanks in advance.
