my boiler is showing f 13 no loose conections what is the prob and is it a comon fault

andy, July 2010

got the same problem at the present time after fitting new power interface and new pcb main board,boiler works fine but then keeps shutting down with f13 code,re starts as soon as i switch the reset switch and again runs fine until the intermitant fault re-occurs checked every wire and connection block to main board till i,m sick of doing it.Getting fed up of re-setting boiler every half hour.keep paying tech guys just to be told what i already know,theres a bad connection somewhere.

Had this problem with mine a few times.... the on/off switch contacts are burnt. Remove the front panel, lower the front of switch panel, behind the on/off knob is a crappy little slide switch. Make a note of the wiring connections, disconnect and remove the switch. With a very small screwdriver/sewing needle, carefully dismantle the switch and clean the contacts inside. reassemble, refit, and all will be ok. F1 codes started coming up too for the same reason...
