Pump staying on at night. Faulty PCB relay or HPA2 m/switch - or ?

You won’t get the answer you’re looking for as we will not give advice potentially leading to diy gas work. Please see forum rules

Not planning on any DIY. Having just spent £400+ on boiler, just wanting to know likely cost to correct the pump problem. A new PCB is a much bigger expense than a new HPA2 valve.

If just the pump is running frost stat / pipe stat more than likely

Don't have a frost stat - thanks anyway

If you’ve already spent £400 I’d look at getting shot mate

Your joking. It’s an investment now😛😛😛

Tend to agree Harvest. Another £50 for a valve (if this is the problem) versus £2.5k-£3k for a new boiler (say Worcester Bosch?) would be worth it. That's why I asked the Q in the first place. 🙂

But if it’s not just a valve then the boiler becomes uneconomical.

So they need an engineer to diagnose properly. Then they go from there.

Roger that Harvest. At least it was worth trying to get a diagnosis via the Forum. Thanks everybody for chipping in.
