The pump consists of a 120 VAC, 60 Hz motor,
impeller, impeller housing, and a removable filter
that helps prevent foreign objects from entering
the pump impeller and drain outlet.
• The pump runs whenever the washer is in the
spin function of a cycle.
• The pump runs if the water level sensor
detects frequency under 36k Hz (overflow
level), and the washer is plugged in. (See
Water Level Pressure Sensor
in the
Fill
System
section of this service guide
.)
• The pump is capable of eliminating 10 gallons
per minute.
• Recommended minimum standpipe diameter
is 1 1/4-inches.
• Standpipe minimum height is 24-inches,
measured from the floor at the washer
location.
• Standpipe maximum height is 96-inches,
measured from the floor at the washer
location.
• The pump motor has an approximate
resistance value of 19.5
W
(ohms)
.
The resistance can be checked from the main
board, connector J512
brown
wire pin 2 to
black
wire pin 3.
Operation of the drain pump can be checked by
using Service Mode test 12 (see the
Service
