My combi boiler led goes red and needs reset.?

Question

I have a 100,000 btu sabre 29he combi boiler and it needs reset sometimes four or five times before it functions correctly. It only seems to happen with the central heating, i've bled the rads of air and made sure there is enough pressure in the system. Any ideas on what could be wrong? Sometimes it works for a couple of hours before the led goes red and needs reset, it's a real pain because i can't set the heating to come on in the morning because it needs reset all the time.

Answer 1

I see its a HE condensing boiler has it been serviced since fitting condensate trap may be blocked Is it OK. Dose it trip out before ignition how far through the start up sequence will it get . fan start up, spark, flame, Dose it ever do it when supplying hot water.?

Answer 2

i imagine your challenge might want to nicely be such as mine: overheating contained in the boiler is tripping the overheat sensor. In my case, it truly is being brought about with the aid of scale construct-up contained in the secondary warmth exchanger that resources warm water. i have purely offered a alternative warmth exchanger and am contained in the frame of mind of searching some genius with a pipe-wrench to come back and do the transplant. you do not element out what's occurring earlier to the boiler tripping. Are you utilising warm water, or purely heating the position? CD

Answer 3

You may find that there is a condensation trap on this boiler. If there is, it is under the boiler, and it is a clear plastic container. You unscrew it and empty any water that has collected in it and replace it.
