Need urgent advice on how to resolve my faulty Vokera Compact Combi Boiler, model number 24MTN.
When I turn on my combi boiler all seems fine for about 30 seconds or so. I get the green light flashing initally to show that the pressure is fine, currently at 1.5 so within spec (min=0.5 bar, max=1.5 bar) and then a static green light. Hot water supply present to both kitchen\bathroom taps and radiators all over the house.
Once the 30 seconds are up, the led at the front of the boiler goes from GREEN to RED and the boiler shuts down suddenly and the water becomes cold. This happens for a few seconds and the led turns green again and along with the hot water eventually.
Can anyone tell me how to resolve this issue as I have read the manual and performed the actions needed as outlined but to no avail.
If it's the PCB board by any chance, is there re-conditioned ones available for purchase?
Appreciate any responces,
