Oil boiler lockout - tried everything or have I ?

Not open for further replies.


We have a Worcester Bosch Danesmoor 20/25 oil boiler that's quite old but has been OK for the 6 years we have lived here. It has on occasion gone into idle mode which I have sorted by pressing the solenoid. However when I tried to turn on the heating a few weeks ago it just locked out after a few

minutes andwhen I attempted to reset it the same thing happened continually. Sincethen I have:

- replaced thesolenoid, photocell, transformer, burner nozzle and bled the oilpipe, cleaned the filters and the combustion chamber

and all to no availas exactly the same thing is happening, the boiler fires up and thenlocks out after a few minutes.

I could really dowith some help as I don't know what else it could be.

It's getting colderup here in Yorkshire and the missus is becoming somewhat impatient!


It would have been cheaper after the first couple of items to seek a Professional solution.
It could be a simple (low priced) fix for a Professional now.

There's still a few things it could be.

Get a pro in mate they'll be able to set it up so it's burning propeely


Oil boilers can kill you as stone dead as a gas appliance can.

They aren't for diy repairs
