Glowworm Micron 40ff led's

[Backboiler]

Why, when following the fault finding guide in the M/I's of a Micron 40FF does it suggest checking 6 LED's when the board appears to only have 2 LED's? I think the lights illuminate in conjunction with the ignition sequence.

I hear what you're saying Gasman and I have to apologise for posting this question in the public section but I posted in here first. It sat here for a day with ziltch response. I had a response straight away in public. In fact I've still had no response here.

dave1---- It has an intermittent fault. It will run for hours and then according to the occupants, the reset light is solid green and the right hand light flashes quickly (I reckon this is ignition fault but why does it occur after a few hours?). They were going to leave the boiler "locked out" until I arrived the following day but apparently it worked again without re-setting after the programmer had switched the CH on. It ran perfectly for an hour and a half while I observed it. I hate intermittent faults

I'm certain the PCB on this board has no small LED's, just the two main ones

There was an update on this boiler that changed from the two lights to 6 lights showing fan, burner, flame failure etc.
Anything around 10 years and older IIRC is just the two light board.
