1 Fan stopping sometimes and casing overheat, fan should run constant but at lower speed when no demand present.
2 Case buckled at bottom and causing air to be sucked into combustion chamber affecting pilot flame stability.
3 pilot partially blocked (may even need a purge on pilot tube with injector removed due to build up of carbon inside tube .)
4 dhw flow switch sticking.
5 pump stopping
corgi job only
Thanks Gazza I am Corgi reg.
Casing ok and fan speed cutting down ok,just I have an inkling the O/H stat may be faulty.
Pilot burning ok and pump running fine.Thanks

Ooooooooohhh replacing a part that "might" not need replacing, hope rogue traders havent got hidden cameras, just the sort of petty thing their "expert" would moan about, smacky wrists all round.
I have glowworm swift flow 80 heating side is ok but no hot water also pump very noisey could this be diverter valve problem
The swiftflow doesn't have a diverter valve.
Is the boiler pressure about 1 Bar with the radiators cold?
If the pump is noisy it may be worn out as these boilers are getting on a bit now although I find they are generally well made and I look after several.
The hot water problem may be due to the flow sensor or board connections breaking.
You may be able to get hot water temporarily by turning on the heating and turning off most of the radiators (you must leave a few on).
