DRAIN CONNECTIONS
GE provides a 7/8” (22 mm) diameter corrugated drain hose
which is connected to the back of the unit to form a high loop.
If additional drain hose is needed, please purchase a drain
hose extension kit with a 7/8” (22mm) copper tube.
NOTE:
Do not use any fittings anywhere in the drainline that are less
than 7/8” (22 mm) ID.
The access hole for the drain line should be 1-5/8” (41 mm)- 2”
(50mm) max.
The end of the drain line is 1/2”
(12 mm), but it is adjustable
to 7/8”, 3/4”, 5/8” (22mm, 19
mm, and 16 mm). If the drain
connection is larger than 1/2” (12 mm), you can easily cut the
drain line to fit the connection.
The illustrations to the right show three ways to connect the
drain supply line.
THE HIGH LOOP
The high loop is necessary for proper draining.
Therefore, the dishwasher has the drain hose
attached to the drain pump and fastened to
the top back of the unit, as illustrated. This
gives the drain hose an automatic high loop,
which is necessary for proper draining. The drain hose is
fastened at the best high loop height.
To eliminate potential drain problems, simply leave this
hose in place.
DO NOT REMOVE THE HIGH LOOP!
IMPORTANT THINGS TO REMEMBER:
 Failure to provide the proper drain connection height
(minimum of 20” (508 mm) above the bottom of the
dishwasher base) or a 20” (508 mm) high loop will result in
improper drainage, which will damage the machine.

No part of the drain hose should be higher than 35” (889
mm) from the bottom of the dishwasher.

The drain hose can be extended to a maximum length of 10
feet (3048 mm). Joints and jointed tubes, if any, must have a
minimum 5/8” (16 mm) ID.

If the drain line is going to be connected to a waste
disposer, be sure to remove the knockout or plug from the
fitting on the disposer before connecting the drain line.

Do not use fittings smaller than 5/8” (16 mm); otherwise the
water may not drain properly.
When the installation is ready, open the supply valve and let
the pressure act for a while. Then check that all connections
are tight and there are no leaks.
THREE WAYS TO INSTALL DRAIN CONNECTIONS
A) Typical connection to sink plumbing before trap
(high loop drain).
B) Connection to air gap then to the trap.
C) Connection to waste disposer with air gap.
NOTE:
Don’t forget to remove the knockout or plug from the disposer
fitting.
