Working on a cxi ultracom 24, my problem is the fault f9, I have 1.8 bar showing when I reset it, when the boiler starts up again Im sure I hear the divert vavle motor back and fore, but the fan does not run for the pre heat, after about a minute I get f9, had a faulty pump onces before and the boiler was still firering then locking out on f5, any idears or ways to check, many thanks
 
Release all the pressure from the boiler, it should go to 0.0bar, if it sits at 0.3 bar then you need a new pressure switch
 
Will try that in the morning, also gonna ring Glowworm technical, bit worried because its showing 1.8 but ain pre heating
