Hi . the flow switch could be stuck. Do you still get hot water and heating?
Yes. Boiler is working perfectly except for the constantly running pump..
How do I solve the problem?
Thanks, ***** ***** do I get one and is it a DIY job.
Or part number, please.
I give you a poor rating.
The flow switch has a totally different function. It recognises hot water flow.
It does , but if its stuck the pump will continuously run . its either the flow switch or the PCB . I gave you bthge cheapest option first. The board is expensive and the flow switch is the component to check first. This boiler doesn't operate like a normal Combi . it operates like a primary store.all the best
End of conversation as pump is now silent.
