Technical description

Control panel button fault

What causes this fault?

This fault occurs when the boiler's control board detects that a button on the front interface is being pressed continuously for more than 30 seconds. The most common reason is a button physically sticking in the door housing or an internal electronic failure within the interface panel. In some cases, moisture or dust ingress behind the panel can cause the contacts to short-circuit, leading the boiler to think a button is held down.
