Hello
Hoping for some advice on a problem I have
I can't get the hot water to work - if I select HW mode on the programmer, the motorised valve can be heard and the boiler fires up but then about five seconds later it goes off again . The central heating side works fine so I don't think it's a problem with the boiler itself.
I had an engineer come out Friday afternoon who thought it was the motorised valve that had gone wrong so he replaced that but the problem remained. After much fiddling he now thinks it must be the programmer and is coming back tomorrow with a new one.
One thing I will say is that , before the HW stopped working, we hadn't been able to run the HW and CH at the same time - it was a case of one or the other (I assumed something had gone wrong with the motorised valve but it didn't really bother me because we just worked around heating the water up and having the heating on)
My boiler is about 5 years old and is a Vaillant ecotec plus 618 and the programmer is a Honeywell ST9400C.
If anyone has any suggestions as to what the problem might be I would really appreciate your thoughts. To be honest, the engineer hasn't exactly inspired me with confidence that replacing the programmer will fix the problem...
