Drainage

The machine comes equipped with a built-in non-return valve on the discharge side to prevent waste water from flowing back into the dishwasher.

The dishwasher is equipped with a

5 ft (1.5 m) flexible drain hose with an internal diameter of 7/8" (22 mm).

Drain hose extensions and adapters can be ordered from Miele.

The maximum drain hose length is 13 ft. (4 m), max. drain height: 39" (1 m).

Use the clamp provided to attach the hose to the dishwashers P trap or disposal connection (see the "Installation Diagram").

The hose must always be attached on the sink side of the P trap.

When attaching the hose to a garbage disposal fitting, make sure the plug which is normally blocking the fitting is knocked out or removed.

The hose can be angled to the left or right side at the rear of the machine.

The existing nipple that the drain hose is connected to may be designed for various hose diameters. If the nipple diameter is to large or to small it should be replaced or an adapter may be used. If the nipple extends more than 2" (50 mm) into the drain hose it should be shortened, or the hose could clog.

The drain hose must not be shortened.

￿Make sure the hose is not kinked or cut when pushing the machine under the countertop.

Venting the drainage system

If the dishwasher drain hose is connected to a floor drain or to a drain pipe that is less than 8" (20 cm) above the floor, the drain must be vented. Otherwise the water inside the dishwasher may siphon out during the wash program.

￿Open the dishwasher door and remove the lower basket.

￿Pull the lower spray arm firmly upwards to remove.

￿Cut off the vent cap located at the right rear of the triple filter system, as illustrated.
