Circulation System - GE Profile PDW8200 Series Technical Service Manual

Circulation System

The circulation system consists of the following
components:
• Inlet cover
• Fine filter and sump filter
• Sump
• Circulation pump and motor
• Hub
• Wash arm assemblies
The inlet cover prevents large particles from
entering the sump. The fine filter (metal) and
sump filter (plastic) prevent fine particles from
entering the circulation-pump part of the sump
(water entering the drain pump is not filtered by the
fine filter or by the sump filter). The circulation
pump is controlled by the control module and can
be activated using service mode (see Service
Mode). The pump pushes water up through the
hub to the lower spray arm and to the main con-
duit. The main conduit supplies water to the
middle and upper spray arms.
Inlet Cover
Caution: Use care to avoid breaking the clip on
the hub when removing the main conduit from hub.
Remove the lower wash arm and main conduit to
gain access to the inlet cover and sump.
Circulation Pump
Note: It is extremely important that the self-tapping
ground-wire screw on the circulation pump is
tightened securely.
The dishwasher must be removed from its instal-
lation to gain access to the circulation pump. The
circulation pump can be activated using service
mode (see Service Mode). Refer to schematic or
strip circuit for motor resistance value.
To Remove Circulation Pump:
1. Remove cover inlet. With syringe, remove all
water from sump.
2. Loosen main pump clamp and pump connec-
tor clamp.
3. Remove hanger that holds motor to tub frame.
4. The Circulation Pump can now be removed
from under dishwasher.
