hi, I have inherited my parents house, but with an ideal he30 isar boiler, fitted some 7 years ago by warmfront.
it was fine then in the last 12 months max, it has fitted a new genuine orange pcb, thermistors, heatexchanger, temp probe, ignition probe, new pump , gas regulator valve all was fine for few months, but now I cannot get it to switch to central heating, only dhw, which works fine. no fault code is displayed, just the number 5, then very quickly c then to d and there it stays, the nylon arm on the side of the cartridge moves from forward position to the rear and back to the front and stays there.
could this be the cartridge itself at fault or something else making this happen,
please help, no hair left to pull out soon.
cheers mike
