Problem with Ideal W2000 RS40 Boiler

[David Evans]

I have an old boiler which had been working fine. But Over past few days I’ve noticed the radiators are not heating up, the boiler will switch off after 5-10 mins. I am getting a blue flame in the boiler. I am getting hot water in the hot water tank, in fact it’s very hot. Just wondering if anyone can give advise what problem may be. The pump next to the hot water cylinder feels very hot as well.

Thanks for reply.

Where would I usually find that?

It would depend on the system config but if pump is in airing cupboard, then m/v would normally be there too.

I had a look in airing cupboard where the pump is but couldn’t see a MV there. Photo attached of pump area
