Hi, thanks again for all the info,
Turned it on today from cold the burner came on for about 10 mins then cut out, the demand light and the HW lights stay on. I had a quick look at the control panel, 240 volt to the motor when the burner stops. ( already swapped the motors around ). Does it sound like its a burner problem now to you ?
on a normal cycle when the burner switches off should the demand light go off and the pump stop. ?
The sensor in the heat store is that the one at the front to right of the expansion tank looks like its behind a heat exchanger or something ? if so that is well secured in with a hex nut.
