Was at one other week, was getting LF intermittently.

I gave it a full strip down, changed electrodes an replaced leaking condense trap.

Had a text an hour or so ago, it won't reset from LF.

I pointed out that the leads from flame detection had seen better days, insulation had come away in a couple of places. Put some tape around them, advised on swapping.

I'm hoping this fault is down to this, checked inlet pressure etc last week an all OK.

One other thing he has mentioned, the pressure has dropped to 0.5 but hasn't dropped any lower.

To think I didn't mind working on these a couple of weeks ago 🙁
 
At least if it doesn't reset you can see what stage along the ignition sequence it fails
