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). � If the hose is to be directly fitted to the drainage outlet on site, use the supplied hose clip. � The hose can be installed to the left or right side. � The existing drain pipe for the drain hose is designed for various hose diameters. The drain pipe must be shortened if the drain pipe extends too far into the drain hose. The drain hose could get clogged. � The drain hose must not be shortened. � Make sure the hose is installed without kinking, pressure or being pulled. 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.
