Drainage

The drainage system is fitted with a non-return valve which prevents dirty water from flowing back into the ma- chine via the drain hose.

The machine should preferably be connected to a separate drainage system on site. If no separate drain- age system is available, seek profes- sional advice.

The machine is supplied with flexible drain hoses with an internal diameter of 22 mm and approx. 1.5 m long.

The drain hose must not be short- ened.

Hose clamps for connection are sup- plied.

Longer drain hoses (up to 4 m) are available if required. Contact the Miele Service Department.

The drainage system must not ex- ceed 4 metres and the drain pump has a maximum delivery head of 1 metre.

Ventilation of the wash cabinet at rear

For machines without DHK Steam con- densor, the rear ventilation of the wash cabinet should be connected to an on- site venting system.

Please refer to the Installation Instruc- tions provided.
