Miele G 4220 Dishwasher User Manual


 
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.
