Baxi main calling for heat fault

if it has three terminals it will work , you just need to work out which coloured wire goes to which terminal, if it is an approved part it will come with a wiring diagram

Checked with the seller the part does indicate which wire goes where will also replace the diaphragm as the boiler is getting on a bit

Will let you know how i get on

Thanks

make sure that you cover the PCB housing with cling film or a poly bag and a towel, as any water leaking when changing the diaphragm will go straight in there and fry the PCB

Sure will do, is there likely to be a lot of water? Or a trickle?

isolate the cold inlet and open the lowest hot tap and you should be fine, there will always be some that comes out every system is different, nothing to worry about just protect the electronics they dont like water

All sorted! The button on the microswitch looks like it had failed.

Replaced the diverter valve as good practice, although the original one looked fine.

Many thanks for your guidance!

Got a problem, there is a slight leak coming from the rear of the diverter valve, the bottom screw is tight but it appears to be coming from the hole in the middle, I thought maybe a screw got loose, but it doesn't look threaded

Any ideas?

Found this, i didnt remove the complete assembly fitted the new diaphragm in situ. So it looks like i need to remove the complete unit, fit the smal O ring at the rear of the brass body and refit?

Is that correct?

Removed the complete brass diverter assembly, fitted the small O ring at the back of the rear spindle, although there wasn't one fiited, all seems well now...
