Help me out here. I thought I knew how a door interlock works and I
suppose the PTC thermistor could overheat and cause a fire, but I
can't see how the load of the main heating element influences it.
Does anyone know what the actual mode of faliure is?

They always have a ridiculous number of models in production. Modes for
different retailers so that they can't be beaten on price, different
countries, etc.
Can this lead to them not being sufficiently focused on quality and
reliability. Too much distraction.

I thought door locks tended to be mechanical - locked by a bimetal device
with a heating element. Could that heater get too hot if in the proximity
of a tub of hot water?
