I have a 9year old Camray 5 Combi. The circulating pump is running continuously without demand from hot water or heating. How do I solve it?

Hi . the flow switch could be stuck. Do you still get hot water and heating?

Thanks, ***** ***** do I get one and is it a DIY job.

Or part number, please.

They can be bought from most plumbers merchants that handle boiler spares.or online parts centre. Yes , you could do it yourself. Do you have the manual? So that you can locate it?

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

Why not disconnect the flow switch and see if the pump stops running . if notvthgen we can take it from there . if you would like me to opt out and open your question to other experts, let me know and I will do so
