Can someone please shine a bit of light on a problem i'm having with this turd boiler. When hot water is called for, it lights for about 30 secs before going out briefly then relighting itself then doing the same thing over and over so the water runs hot, cold, hot, cold. I've only been a gas engineer for 2 years and i've come across this problem many, many times with other boilers but i'm a bit stumped on this one because i have done the obvious things like cleaned the plate heat exchanger, changed the dhw thermistor, checked the condensate isn't froze, removed the wires from the condensate trap to see if it does the same thing (which it does), checked the wires and leads for continuity and changed the flame sensing electrode but it's still giving me grief. I don't want to start throwing parts at it so any help will be much appreciated.

I would say blocked plate, have you taken it off to clean it. what is the flow at the hot tap.
Typical symptoms of blocked plate heat exchanger.
yeah, i cleaned the plate h-e good and proper. The flow rate is 8 l p/m.
Could be the burner isn't modulating.
So you are just getting full burner. At 8 litres/minute the boiler
will soon get too hot and shut off the burner.

I adjusted the burner already cos it was a bit high originally but still it was doing it.
So if you are a "gas engineer" and thus Gas Safe registered all you need to do is register for the CC.
