Venting the drainage system

Only if the dishwasher drain hose is connected to a floor drain or to a drain pipe that is below the level of the lower baskets wheels, the drain must be vented; otherwise the water in- side of the dishwasher may siphon out during the course of a wash program.

Vent the drain:

Open the dishwasher door.

Cut off the vent cap located at the right rear of the dishwasher, behind the filters, as illustrated

Additional note.

Since all Miele dishwashers are equipped with an odor trap and non-re- turn valve, the drain hose can be con- nected directly to the drain pipe as illus- trated.

If plumbing codes require an external air gap on the discharge side of the dishwasher, the following requirements must be met:

–No part of the drain hose should be higher than 39" (1 m).

–If installed horizontally, the drain hose can be up to 12 ft. (3.5 m) long. If the drain hose is angled upwards in any way, it cannot be longer than 5 ft. (1.5 m).

–The drain connection should be made as close as possible to the dishwasher.

–The internal diameter (7/8" or 22 mm) of the drain hose should not be re- duced beyond 3/4" at any point.
