7. Functions
This section describes the individual functions, explains the corresponding components and how they
are to be installed and removed.
7.1 Safety system
Should functional defects in the dishwasher control system or in the structural elements occur, resulting
in an over-filling of the machine, the valve combination will be closed by means of the safety system,
thus blocking off the water supply.
The safety system is based on an “active” system.
The electronics unit permanently monitors the safety switch in the base pan, even when the dishwasher
is switched off. If water gets into the base pan, the safety switch will be activated and the dishwasher will
switch on.
The electronics unit recognises that the dishwasher has been switched on via the safety system and im-
mediately activates the discharge pump mode. The aquastop valve is deactivated.
Error code E 15 or a flashing tap LED show the customer that there is a fault.
The dishwasher will not be able to be operated until
• the cause has been rectified and no more water is in the base pan;
• the appliance has been disconnected from the mains.
If leaking water gets into the base pan via the rinsing cavity and the flow-off channel, further overflowing
can be prevented if the discharge pump is switched on.
If the supply hose is faulty, water will get into the base pan direct through the outer hose (leak water
hose). The aqua stop valve will be deactivated.
