7.2.1 Functioning
Leaks which occur in the region of the valve or the
supply hose are led into the base pan through the
leaking water hose.
A styrofoam float triggers a microswitch to activate
the electronic safety system. The coil of the
aquastop valve is deactivated by the electronics
unit and stops water from flowing into the dish-
washer.
