Hi, welcome to Just answer
How old is it ?
hi mate, 8yrs
Thanks Malc, can you please elaborate the problem
yes, was being intermittent previously
fault reset ok, then suddenly went off and fault leds permanently on
24 is safety thermostat and 26 is due to low pressure or bad pump
when was this unit last serviced ?
about 4yrs ago im afraid!
long time...these should be serviced at least once every year
ps. pump runs ok
fault lite says fan/flue
and flame fail, blocked cond drain
these all seem ok
wondered if it could be pcb?
what about the pressure? Is it fine ?
yes no problem
the pump is running so is the fan and flame fail, flow switch etc are all fine so it is the PCB..however, I will check the wire connectors to the PCB before replacing it
yes wondered how i cud check pcb as fan goes blip for a mo after reset but then stops
Check this image this is how a good one should look like
yes, so just check all conections you mean; wanted to try and prove it if poss
This is not the kind of fault that is suitable for DIY, best to get a breakdown specialist out for it....however, if you still want to DIY then follow these instructions
1. Note the settings of the temperature controlknobs. Rotate the knobs fully anticlockwise andcarefully pull them off the drive pins.2. Remove the screws securing the control boxcover and release the cover retaining barbs fromtheir slots. Disengage the rear of the cover fromthe control box hinge pin3. Note the position of all plugs and wires on theP.C.B. and disconnect them.4. Undo the securing screws and remove theP.C.B. Transfer the control knob drive pins to thenew P.C.B. and turn them fully anticlockwise. 5. Reassemble in reverse order, ensuring that thetemperature controllers are reset to their previouspositions.
