5.2.32 Drain Pump - Removal

The drain pump is a self contained motor and pump assembly
mounted directly into the sump by the induction or inlet nozzle
equipped with a neoprene multi-lipped cylindrical seal to
prevent water leakage. A single Phillips head screw holds the
complete motor and pump to the sump. Removal of the drain
pump is accomplished by the following procedure:
CAUTION. Switch off electrical power supply
and turn off water supply at main or
dishwasher shutoff.
5.2.32.1 Refer to section 5.1 to gain access to the drain
pump.
5.2.32.2 Disconnect the two Quick Connect terminals and
wires from the 1/4" terminals marked "L&N" on the drain
pump motor. The terminal marked "L" should be connected
to the wiring harness wire marked "G2-D" (drain), which is
connected directly to the overfill switch. The neutral of the
drain pump marked "XN-D" should be connected directly to
the "N" of the main terminal block. For rotary models, the
neutral wire is marked "W2-D" and connects to "N" of the
main terminal block through the wash pump motor plug.
5.2.32.3 Remove the drain hose double coil hose clamp with
a pair of hose clamp pliers from the pump outlet nozzle as
shown below. Remove the molded drain hose elbow from
the pump outlet. The molded elbow of the drain hose has
two offset slots in the end face of the elbow, which engage
with the offset lugs on the pump cover/outlet. This feature is
to index the drain elbow/hose into the correct angle and
position it in relation to other internal components.
