Safety systems

Several safety systems in dishwashers guard against leaking.
Leaking water is directed into the base where it's detected by the
float switch, which stops the wash cycle, turns off the water valve
(if it's on) and turns on the drain pump.
Even when the dishwasher is off, the float switch detects water,
turning on the drain pump and generating an error code (e.g.
E:15). The dishwasher cannot be run until the leaky part is fixed,
the water is removed from the base and the control is reset.
4.6.1 Float
The float is a safety device, located next to the sump, which
activates if there's too much water in the base. If water collects in
the base, a styrofoam float rises and engages a microswitch,
stopping the wash program and starting the drain pump.
