Myson Apollo 30Si Not Lighting

Had to look at a Myson Apollo 30Si that was not always lighting. Another engineer had looked at the boiler and replaced the PCB and sleeving to the spark electrode lead but this had not solved the problem.

The boiler was lighting intermittently. Sometimes it was lighting within a few sparks other times it would spark for ages before lighting if it lit at all. When the pilot flame lit it looked adequate but maybe a little on the small side. I stripped the pilot assembly down and cleaned the pilot injector out as thoroughly as possible as I could not remove the injector from the pilot assembly.

I re-assembled the boiler and the pilot flame was larger and lighting quicker which looks like it solved the problem.
