Would appreciate any advice on a Halstead combi that simply fails to shut off when the desired temperature is reached.
Demand for HOT WATER- Works perfectly! Demand for CH - sometimes refuses to fire up but doesn't go to 'lock out' eventually starts but won't shut off. Thermostat on side of boiler but not in living room.
As a new PCB is £142 i'm worried I could swap it and be no further forward.
Sincerely appreciate any experiences you've had with this boiler (or any other) that I can learn from.
Many thanks
