I wonder if anyone has come across this fault and could guide me.
When drawing hot water, the boiler fires up as normal and the hot water runs for a couple of minutes, then cuts out for 15 seconds or so then comes on for a few seconds then off again. If the CH thermostat is turned right down below ambient temperature, the water runs hot without stopping.
It's not the flow switch and I swapped in the main driver board, without success.
If anyone has come across this fault, could they give me a helpful suggestion.
Thanks in anticipation.
