This might save someone a little time....
Installed two years ago and has not been serviced since then.
Started to need the reset button to be used more and more frequently, some ignition sequences resulted in a thump as it ignited, then it finally started to show an LF fault several times.
Cleaned the condensate trap out, which was quite mucky, but not choked -then moved onto the ignition and flame detection. The electrode gap was 12mm (should be 3.5mm) due to the none earthed electrode having drooped down due to heat. The drooping electrode made it very difficult to get the ignitor out through the hole and there was some dark deposites on the outer insulator probably from it arcing down the outside to ground.
As a temporary bodge - attempted to straighten the electrode in the vice and the metal started to fracture, so arc welded across the fracture until a replacement can be sourced.
Boiler back in working order, no faults indicated.
