The waterproof system has been activated. One of the


Too much water has accumulated in the steam condenser.
Wash water may have been diverted behind the protective
panel of the steam condenser on the back wall of the wash
cabinet because of angled load items or injector nozzles.
When installing angled injector nozzles and sorting load

items, ensure that the wash water outlets point towards
the centre of the wash cabinet.
Restart the cleaning machine. Excess water is pumped

out automatically.

Ethernet interface, but only a serial interface (RS232) is
activated in the controls.
Deactivate the RS232 interface:


XKM RS232 10 Med module to set up a serial interface.
The peak load cut-out has lasted longer than 3 hours.
