5.1 All-Around Water Protection
Aqua-Control Inlet Hose
The inlet hose has a double-wall construction. The inner hose is equipped with a flow restrictor built
into the tap connection, and has a flow rate of 4 litres per minute. The inlet valve (1) is located in the
base of the dishwasher. The safety outer hose (12) is connected to the regeneration chamber. If the
inner hose should burst, the water passes into the tub. The safety pressure switch activates the drain
pump and decreases the waterlevel down to normal level. An additional overflow protection is a
defined overflow through the regeneration chamber. The water flows into the bottom tray and
activates the float switch, which energises the drain pump. This drains the dishwasher preventing
water damage.
Safety level
If the safety level is reached by over-fillling, the safety pressure switch starts the drain pump. The water
is only drained until it has reached the normal level because the reset point of the safety pressure
switch is above the switchpoint of the normal pressure switch.
Leakage Protection
The anti-flood switch in the base tray will activate the drain pump and drain the water from the tub in
the event of an internal leakage. If the float switch is activated, all electric components are switched
off except the electronic and the drain pump.
