Circulation Motor and Pump Assembly

The circulation motor is a DC Brushed Motor; it
has onboard AC to DC rectification. Resistance
cannot be properly checked on this motor
because of the rectifier and diodes inside the
motor shield.
Circulation Pump Motor Assembly Removal
1. Disconnect power to the dishwasher.
Remove the toe kick panel, door, and sump
(see Door Removal under the Door section
of this service guide, and Sump Module
Removal under Sump Module, in the Tub
section of this guide).
2. Loosen the outlet wash motor (diverter) clamp.
Clamp Removal Tip: Use a small screw-driver
inserted into the ear of the clamp and move the
handle back and forth to loosen the clamp. The
clamp can be removed and discarded when the
component is removed. The clamp kit (Part #:
WD02X25470) contains a single clamp for the
diverter connection.
3. Use a large flat-blade screw-driver to slide the
circulation motor out of the floating seal. As
the pump assembly is removed from the seal,
slide the wash motor off of the hanger (use
care to not lose the hanger grommet), and
remove and discard the one time use clamp.
WARNING: GEA Factory Service Technicians
are REQUIRED to follow Lockout / Tagout
(LOTO) 6 Step Process prior to beginning
repair.
Use the flat-blade screw-driver to remove the
floating seal from the sump, using care not to
damage the inside sealing surface.
