LF code showing up

cleaned condense trap and checked to make all clear and is fine, and spark electrode had to be re-positioned as slighty bent so was not sparking, it ran for 10-15 mins then LF showed up

I was thinking maybe flame sensing probe duff

Any advice would be much appreciated
 
dunno, but let me know too cause i have the same one to go to on friday on an unvented🙂.lol
 
Check gap on electrode with a pound coin, check insulation has not fallen over in burner and is covering probes. Check all fixings to top of burner are actually tight as I've been to a few where they had come loose and the heat had warped the boiler casing/structure so badly I had to ID it.

Failing that, large hammer or a gallon of fuel and a match, depending on personal preference.
 
you need a gasket kit for this dont you?.
can you actually bend the electrode?. i realise they are a bad design and the last one i had i actually snapped it of because it was so far bent.

mine is showing 3/4 bar also.
 
You need to replace the ignition electrodes, the flame sensing electrode, the 2 earth pins in the front and rear of the heat ex and then check all the earth wires everywhere.
