    the above chb keeps locking out on code 03 fan/flue fault.gas man has checked pressure switch,fan & cleaned venturi.s but still locked out.i must stress that after cleaning venturi,s it resets itself now so don,t actually have to reset knob like before.he says could now be the pcb but wondered if anyone had experience of this fault.

    many thanks lj

    Problem would be easier to diagnose with a bit more info, however you are unlikely to get much help here as the problem is quite likely to be in RGI zone.
    Call an engineer (Vokera may tell you a local approved chap). Try to get a no-fix-no-fee deal.

    did he actually remove the venturi? often they just get something poked through the front, that doesnt clean the negative venturi properly.

    he removed flue hood & cleaned/washed/dried out the venturi,s but still randomly locks out & resets itself.he rang vokera but they didn.t offer much help apart from suggesting pcb but he didn,t want to fit it without being sure.

    its a single coil fan so if it is spinning at different speeds it could cause intermittent lockout. either bearings are tight again or its not getting the right voltage.

    it would be an uncommon fault if it was either fan or pcb.

    what length of flue run is there, ie, does it immediately bend and go outside or has an extension kit been used

    vertical terminal could be rotten. FGA usually shows this up if its bad enough to cause lockout.

    spoke again to gas man & asked him about fga reading.He says it was low & he did a visual check of the flue/terminal.Does this leave possibly the pcb as the likely problem if all fan/flue problems have been checked.

    Many thanks lj
