Halstead(i get all the best jobs haha) ace high - hot water is fine, no heating....

Hi Guys,

I thought I would be best off asking for this one in lieu of the wealth of advice on here.

I have a landlord with a halstead ace high combi, boiler fires and stay on all appearing to run fine, no noise, no over expansion. However when heating is switched on pump runs, fan runs, fires for 30secs then stops then about 5-10mins later fires again with no heat coming to the primaries. flow switch works. just wondered if anyone had come across this as a common fault or had any advice on what to check for?

Cheers

Pooly

Stuck diverter valve ?
Broken pump impeller?
Just a guess

Diverter seem to move ok and pump seems to be running ok.
