Baxi duo-tec 2 combi 24 ga no hot water no fault code

[johnnyboyoy]

Hi there, went to look at the above last night. Heating fine. Hot water, led flashes on Hall effect sensor. Boiler display never shows demand for hot water. Checked between red and blue from HES on pcb for approx 5vdc, flicked between 1.25v to 2.5v. Flow chart says that if I have approx 5v change HES and if not change PCB. When reading the introduction to DHW in this boilers manual and in the flow chart for the main combi elite (which I'd thought would work in a similar way) it seems to suggest that the diverter has to move in order to start firing sequence. Guess I need to call baxi tomorrow but wondering if anyone has any experience of this? Thanks

Pm a copy of your gsr card to gas man.

he'll give you access to the private forum.

When you're in there I'll reopen and move this thread for you.
