Posting again because I am close to wits end with this. I have multiple visits from heating engineers and nobody can diagnose the issue let alone fix my Worcester boiler.
I am getting closer but since I have already spent over a grand I want to try to do a bit of detective work on my own before it costs me more money.
The last three times the burner has run for 24 hours before locking out, and on each of the last three times there has been a sort of slimy film on the nozzle filter. Last time the guy was here he said - and I agreed - that there was no point putting the new nozzle on because it would likely do the same again. He reckons it is the fuel supply.
I have had a paste test done and there is no water in the storage tank.
The oil in the tank (which is new) is clear.
HOWEVER
When left in the collection jar I have been using it goes cloudy.
I am now running tests with the oil to see if oil stored inside the house goes cloudy the same as the oil left outside.
I thought it might be temperature related.
I spoke to someone today who said the temperature drop might be illuminating the problem but was unlikely to be the cause.
So far the oil stored inside the house has not gone cloudy like the oil left out overnight.
I understand the difference between normal water content and emulsified water content, but the person I spoke to today did not think a bit of water content would repeatedly foul the burner nozzle.
So, can anyone shed any light? So far I have been unable to find anyone who can nail the issue.
