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.
