I was called to a routine service today on the above boiler. When I arrived the customer told me she was also having a problem with the hot water. What happens it runs for 4-5 minute then cuts of ( hot water ) the green fault light then flashes maybe 4 times per second. You then have to turn the boiler of and on to reset it then works fine again, I only scheduled 1 hour 30 minutes to this job. So I had 10 minutes to look at this problem after the service.

In the manual which I had in my laptop.The fault code ( flashing 4 times per second ) had about had about 7 possible faults it could be.

I explained to the customer I would be back to rectify this problem as I was short for time.

Have any of you guys came across this before . I just want to shorten the 7 possible faults down and go for the most likely faults first.

I have listed the faults in the manual below

FAULT FLASHES 4 TIMES PER SECOND
Code plug missing or failed.CH or DHW Sensor fault or out of position.Air pressure switch fault or condense in tubes.Fan fail or stiff.Blocked flue.Faulty harness.​
Board fault.
