Glowworm Boiler Ultimate 80 - not getting hot

[pioneer2222]

Hello, Glowworm ultimate boilder suddenly decided to stop getting hot, it's lighting up fine but its stone cold, therefore nothing else is warming up.

Any suggestions?

Could you be more specific? Glow worm have made more than your boiler, which we don’t know which it is.

So it should a non-combi boiler, this will likely be a motorised valve fault. Do you know if you have an S plan or Y Plan? If unsure post a photo. You say it’s suddenly stopped getting hot, for hot water, heating or both?

It's S Plan, and both.

The actual gas boiler downstairs is igniting but it isn't getting warm, I think the MVF's are fine I can feel the flow.

If it’s firing up, but cold, could be the pump.

Bringing the cold water into the boiler you mean?

No, as in not circulating

It's circulating cold water because the boiler isn't warming the water. As I said the boiler is firing up but the boiler itself isn't warming up. Normally it feels warm.

It's circulating cold water

Are you sure it's definitely circulating?

I used to have the same boiler, by the way! Do you hear the fan, then a click click, and it ignites the pilot? Then what happens?

Then not much, I can see the orange thing, and it sounds like it normally does. Normally it would gradually feel warm but nothing in this case.

There's a little drip drip in the cold water feed in the attic, could that be the problem?

Doesn't sound like your boiler is firing up at all. If it was ,the heat created would be going somewhere,if only a short way through the flow pipework.

Fault finder says if pilot comes on, but not the main burner, it could be a solenoid.
