oh I absolutely agree with you, I don't think they have diagnosed this right, but they have replaced everything that a D1 code could throw up except the PCB board. I am writing all this down, and before they send the engineer out for the 7th time this year, I will ring his manager and ask. The manager of this firm has been liaising with Vokera and even they are stumped. The firm my insurance use is Heatserve based in Wolverhampton.
The boiler itself is working at the moment, ive got it running at a high temp setting, it seems to cut out when the boiler starts up on a low temp setting for some reason. but as I say, this boiler has been a bad one from the start.
Do you have a direct number for the Service manager south for him to ring him please? Many thanks for your help.
