Any ideas? Bentone electro oil Inter10 pl10/4 pump/burner assembly This symptom doesn't seem to be listed anywhere. (commonly seems to be cutting out within 30 secs or so). The tank filter has not been changed in 18 years(!!) but when fitting a new plastic tank 5 years back paper filter looked perfectly clean and no sediment in botttom of glass bowl so I left as was.( probably rinsed it in fuel) Photocell is clean, fuel is flowing ( not sure if fast enough, firing rate stated as 40ml/minute and would certainly seem to easily match that) . Some sediment appeared in the first jamjar of oil after disconnecting flexihose at boiler. 2nd jamjar seems to be clear. I assume this may have been debris from the hose perhaps although it was a browny colour and looked like tiny bits of chipboard !! No evidence of water or air in these samples. My user notes for the boiler state that there is an internal filter for the pump but I have no idea where this might be. I guess I should just change the tank paper filter but access is very difficult in the new tanks position so if anyone can help in the pump filters location and what to undo to look at the oil pump itself I'd be very grateful, thanks PS The nozzle is original I think and would like to replace. How do I establish which danfoss series ( ie H,EH, S,ES orB) nozzle I need, I found the size specification somewhere but not to hand at the moment.
