Hi,

Help please!! What does this mean? How can I get my boiler re-started. Thanks.

PS Status code is S.0 which means no heat demand...

Thanks!!

New pcb needed

Is the heating or hot water calling for heat?

Might be mainboard failure.

Presumably you disconnected the mains power for a few minutes and then repowered ?

It very occasionally works on some microprocessor devices.

Does anyone know what the actual PCB fault is that causes this?

It is a communication fault between the main pcb and the user interface.
It is usually caused by a low voltage short circuit, causing an incorrect potential difference in VDC to the UI

But I gather its a main PCB fault. Do you know exactly what is the cause on the main board?
