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. If the inner tube starts bursting, the water reaches
the floor pan, gets diverted to the float switch in the floor pan and enables the drainage protection.
In this case the electric valve at the water hose get voltage free and the water connection gets locked.
The drain pump additionally pumps off the dishwasher so that no damage by water could be
produced.
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 water level in the detergent dispenser transcends the overflow protection switch ”Safety level”(4), the
water passes over the overflow protection switch (5) in the floor pan and also activates the float 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.
