What do you mean by this? The pressure switch is normally connected
via a pipe to the bottom of the sump. As the machine gradually the
fills the weight of the water compresses the air in this pipe and
eventually activates the pressure switch thus cutting the valve. This
action will work whether the door is closed or not.

I was thinking that if perhaps the overfill detection is achieved via
a two-stage pressure sensor then if your pipe were blocked/damaged
then this would prevent the sensor activating.
