Hi,
I have a Worcester Bosch Heatslave 18/25 oil combi. 5 years old, serviced annually. All appears fine but it sometimes goes to lockout when the heating is on.
Its the 'boiler lockout' that trips not the flue or burner one so the lockout light doesn't come on.
The burner just stops but the pump keeps running. it works fine for a day or more once reset.
Any ideas?
