Glow worm compact 75e combination boiler.
problem:
the water is only just getting warm at every hot tap and shower unit, too cold to get a shower. flow rate reduced and hot water gets hot.
burner pressure checked, 8mb
burner pressure should be 14.7mb
Solution:
increase burner pressure, but found that it was set to maximum, no extra adjustment would take it above 8mb
Replaced gas valve for new one, fault was worse with no burner pressure but think we have a faulty new gas valve.
We suspect that the problem is either gas valve or PCB, has anybody had similar problems?
We have also recently replaced DHW NTC (Thermister)
Regards.
