Tony, Although i'm an electronic engineer this is the first time I have tackled a boiler and the manual provides limited information. Experience is a great thing - I doubt you could tackle an aircraft avionics system as I would. John

Thanks Bazdaman, I had shorted out the CH (harness side) and turned tap on. I had thought the DHW side must have been ok because pump seemed to be running but the DHW side was open circuit - so it was the flow switch on this side. On top of this the thermistor on the...

Am I right in thinking both must work (short) in order for the DHW to work, but only CH for to get the CH to work John

Thanks for the replies. Does anyone know if the pump has a separate flow switch or is it just the 2 flow switches on CH and DHW. John

Yes I double checked the switches on the control board - there are 2 either side of ribbon cable. All links are the same. Off the top of my head there is only one link on the power board - but it is the same also.

"With a demand for CH you can see the continuity on the pump proving ( flow ) switch if the pump is running" - not sure which switch you mean here John

Thanks Tony for the reply. When you say pump proving switch is this the CH flow switch that Bazdaman mentioned or is there another switch I have missed. I pulled the connector off the CH flow switch and shorted the connector (CH did nothing at this stage), turned the tap on and the fan and pump...

Thanks bazdaman I will try that. Tried that did not work. I notice fan not running on CH but running on DHW but still no spark. The pump runs on both

Hi, I don't think there is a pump flow switch - there are separate ones on the CH and DHW - but it does not work on either so I don't think it is that. As far as the "engineer" is concerned I called Baxi and got some numbers close to me but they were all too busy to attend due to Xmas and...

Hi, I have a Baxi Genesis 80. It has stopped working - it will not fire on either CH or DHW. The green power light is on, the pump runs and the fan runs (on hot water - haven't checked the fan on CH). An engineer attended and said the pressure switch needed changed - he changed it and no...
