Good evening and hello everyone. Not posted for a while. But here we go - so the boiler fires ok heat and DHW all fine for a while then the burner goes out and red fault light blinks once a second. When pressed reset for 5 secs it blinks even faster, about 4/5 a second. Oh the pressure gauge also goes upto 2 before it stops.

Bear with me on this one, looked at the manual on line and there are a lot of possible faults of which most likely seem to be a blocked hex what do you think? Your views please

Thermisters are common fault. One on top of burner ?
