Hi looking for advice please
Have Vaillant Turbo Max 837E boiler, the dial temperature set at 42 degree (on 10 clock where as used to be 2oclock if you know what I mean), however when water comes out the tap it continues to go warm, hot, boiling hot, cold, within 10 seconds it can go from 28 degree to 51 degree, then back up to hot and down again, it is the same in our Aqualisa "off the wall" electro thermostatic shower, in the shower the water is hot, really hot then really cold with no warning (not great for the kids)
Been fobbed off for years its the heat exchanger as also have problems with central heating side, have had it changed and no difference
Is this the thermostat (PCB) ?
I pay British Gas homecare nearly £40 a month and not getting anywhere
Can anyone give any suggestions ? Many thanks Andy
