G1000 / G2000 Dishwashers

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.
