I have a Worcester Heatslave 20/25 with bentone b11c burner, The burner has started randomly locking out, it can run for 30 minutes or 10 hours before locking out, it always resets and fires straight away.
I have cleaned the oil filter and checked the photocell which are all fine.
I do a lot of boiler repairs on gas boilers but not on oil boilers.
Any advice?
