anyone help me out on this, tried 3x flow sensors and one pcb. Wiring plug looks ok and I don’t think this one has a hot water temp sensor. Doesn’t recognise demand at all
Must be the harness then. Not common but there is nothing else involved in the proccess on that one. like you say the Pro doesnt have a HW NTC only a Preheat NTC.
Have seen it once or twice where there has been a drip or leak in past got onto the 3 pin plug going onto the Aquasensor with ever so slight corrosion and thats been enough. Seen it quite a few times on the Betacom 2 that runs essentially the same system but the aquasensor is located at the back of the boiler and if there is flue water ingress this happens.
Well it’s an ecotec so it’s definitely had water leaking inside. I would have thought the connector would be clear of it but the problem only seems to have come up since the last guy replaced rhe diverter so maybe he drenched it!
