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

Can you reset the LF error?

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.

 

[REDSAW]

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.

yep best to take the gasket kit with you, but its very expensive for what it is.

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.
