The WaterProof System (WPS) consists of a number of interdependent safety
features, which provide protection against water leakage.
1.
Protection against solenoid valve leakage:
Each water intake is controlled by an inlet valve. If this valve cannot close
properly due to some defect or blockage by a foreign body, a
second inlet valve
ensures that the water supply is shut off.
2.
Protection against water intake hose leakage:
If a leakage occurs, water flows along an outer hose sleeve surrounding the
intake hose to the drip tray. Here a float switch then
acts to switch off a micro-
switch, which closes the inlet valves to cut off the water supply.
3.
Protection against dishwasher overflow:
If some defect has caused the water level in the appliance to rise so that it
overflows into the drip tray, and the water quantity sensor has
also failed, the
float switch is activated. This switches off a micro- switch, which closes the inlet
valves to cut off the water supply. At the
same time the drain pump is activated.
4.
Protection against drain pump failure or blocked drain path:
In this case the water level in the appliance rises until it overflows into the drip
tray where the float switch is activated. This switches off a micro-switch, which
closes the inlet valves to cut off the water supply.
Warning
If the WaterProof System (WPS) is replaced, always ensure the
correct flow restrictor is installed.
