The integrated Waterproof System offers protection from water
damage, provided the following conditions are met:
– The dishwasher is correctly installed and plumbed in.
– The appliance is properly maintained and parts are replaced
where it can be seen that this is necessary.
– The tap has been turned off when the appliance is not used for a
longer period of time (e.g. during holidays).
The Waterproof system will work even if the appliance is switched
off. However, the appliance must remain connected to the electricity
supply.

gets damaged, switch it off at the mains immediately and call Miele.
