Glowworm compact e not firing

[Stu777123]

Hi all,

Unfortunately my boiler packed up this morning so looking for ideas of what it might be.

Before it packed up it was I had CH on and kept continuously.firing up for 5 -10 seconds

both DHW and CH are not working and DHW doesn't work if I switch to DHW only

the demand light comes on for CH and DHW but it doesn't fire. There is no red light showing and I think the pump starts working

I change the PCB earlier and still the same problem

I realise it's an old boiler and probably needs relplacing but want to keep it till renovations take place

Be grateful for any advice or knowledge of common faults of this nature

Could be the diverter valve, could be the flow switch for dhw and the microswitch for the heating. No idea why you changed the pcb, desperation perhaps?

I had a spare PCB sitting around and read someone else adviced it to someone with a similar problems
