Drain Pump Assembly
The drain pump assembly is located under the tub
at the right rear corner. The drain pump operates
on 120 VAC and is energized 90 seconds after the
wash pump shuts down to remove any water in the
dishwasher sump. The drain pump forces the water
out the drain line. A check valve fl apper on the drain
pump prevents the dirty water from reentering the
sump.
The drain pump has an approximate resistance
value of 27
Ω
.
Operation of the drain pump assembly can be
checked by using the service test mode. (See
Service
Test Mode
.)
To remove the drain pump:
Disconnect power.
Open the dishwasher door and remove the
bottom rack.
Remove the dishwasher from its installation.
Lay the dishwasher on its back.
Cut off the plastic tie and disconnect the 2 wires
from the drain pump.
