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.
