Wash Cycle
Water and debris flow from the tub,
into the sump chamber (1). A metal
impeller blade pulverizes the larger
debris as it moves through the nut
grater (2) and upward (3) towards the
lower spray arm.
A portion of the water carrying debris is
diverted from the spray -arm path and
moves through the filter coupler (4),
into the fine filter (5), and through the
fine screen (6) which traps the debris.
The debris tumbles down the incline,
passes through the check ball coupler
(7) and settles at the bottom of the
collection chamber (8).

Drain Cycle
Water and debris flow from the tub
into the sump chamber (1), through the
metal impeller blade of the nut grater
(2) and upward toward the lower spray
arm.
2. The drain solenoid closes the drain
valve (3). Water is directed into the
bypass drain connector (4) and moves
into the collection chamber (5). Water
pressure pushes the filter check ball (6)
upwards, closing off the passage to the
fine filter.
3. Water and collected debris pass
through the drain hose connection (7)
and are discharged through the drain
hose.

Components
Motor-Pump Mechanism
To Remove Motor-Pump Mechanism:
1. Remove the spray arm, fine filter, sump cover,
and cap. Remove all water from sump with a
syringe.
2. Lift up on the edges of the sump boot , squeeze
inward, and push the sump through the opening
in the tub floor.
Note: Use care not to lose the check ball from the
collection chamber passage in the sump.
Spray Arm and Fine Filter Assembly
To Remove Spray Arm and Fine Filter Assembly:
1. Remove the lower rack from the dishwasher.
2. Gently pull the tab back on the base spray arm
and lift the spray arm up and out .
3. Remove the 1/4-in. hex-head screw that
connects the spray arm base to the fine filter
assembly.
4. Gently push the same tab in to lift the fine filter
assembly up and out . (See step 2.)
5. Clean fine filter screen if soil is present .
Note: Ensure that the check ball is clean and not
blocked. It should move up and down freely.
Note: When installing spray arm, make sure the
metal bushing is in the spray arm base. (See photo
below.)
Note: When installing fine filter, make sure the drain
port of the fine filter is engaged to the vertical drain
port of the sump with check ball in between. (See

3. To remove the access panel, remove two 1/4-in.
hex-head screws from the bottom of the panel.
Loosen the 2 Phillips-head screws at the top,
slide the panel to the left , and pull toward y ou.
4. From below the tub, loosen the 1/4 -in. hex-
head clamp from the top spray arm hose (if
applicable). Remove the electrical connections
and remove the 5/16-in. hex-head screw from
the hanger that holds the motor to the tub
frame.
5. Loosen the 5/ 16-in. hex-head clamp from the
bottom spray arm hose. The motor-pump
mechanism can now be removed from under
the dishwasher.
(Continued next page)
Note: If the collection chamber is removed from the
sump, the check ball will fall out .
To assemble the collection chamber and sump, align
the collection chamber tab with the slot in the sump.
This will assure that the check ball will seat properly
when the drain cycle is performed. If the collection
chamber is not alligned properly, the check ball will
not seat and the dishwasher will not drain.
Note: After installing the collection chamber, drop
the check ball into the sump tube from inside the
tub before installing the fine filter.
WARNING: Sharp objects may be in the sump - use
proper safety precautions.
A foreign object trapped between the food grater
and the grater nut will cause noise to occur. Remove
the spray arm and fine filter (see Spray Arm and Fine
Filter Assembly) to access the sump.

High Drain Loop/ Air Gap
A high drain loop/ air gap is necessary with the new
water distribution system. Without a high drain loop
/air gap, the dishwasher will drain during the wash
cycle due to a small amount of pump pressure in
the extra fine filter.
Main Motor
The pump motor on models with the new water
distribution system starts and stops during the
wash cycle. The pump motor stops to allow the
drain valve to fully open at the end of a drain cycle.

Washability Complaints
Hot Water – Ample supply of water at 120°F
minimum temperature is necessary. Do not use
dishwasher soon after using clothes washer, or
filling bathtub.
Loading – Consult Owner’s Manual on loading
procedures.
Amount of Water - Make certain dishwasher is
level. Allow dishwasher to fill normally for the first fill
and drain completely . Allow dishwasher to complete
the second fill and check water level. Water should
cover the bottom of the flood float cover. If water
level is low, check for clogged screen in water valve,
and check float switch.
Detergent Cup Leakage – Some moisture in cup is
normal. It must not be soaking wet and oozing out
and down the inner door panel. Refer to section on
detergent cup if leaking.
Proper Amount of Detergent – Use full detergent
cup of fresh detergent in hard water. Use only
enough detergent to get good wash performance in
soft water.
Rinse Agent – Use rinse agent if spotting is a
problem.
Water Valve – Check valve for intermittent
operation. Valve coil can be tested directly.
Spray Arm – Check to be sure spray arm spins
freely and jets are not clogged.
Filter and Drain System
Will Not Pump Out
1. Check routing of hose system. It must be free
from kinks.
2. Check for blocked or partially blocked drain line
and air gap.
3. Check operation of check ball. Check ball should
be up in drain and down in circulation.
Note: If the collection chamber is not alligned
properly, the check ball will not seat and the
dishwasher will not drain.
MOTOR-PUMP MECHANISM
Motor Stalled-Hums
1. Disconnect Power. Try to turn motor shaft
clockwise to determine if seal is stuck and
can be broken loose. If motor shaft cannot be
turned, cutter blade may be bound up. Proceed
to step 2.
2. On inside of dishwasher, remove sump cover.
Remove the cap in sump and reach down
into the sump. Check for blockages, such as
bone, wire ties, etc. If it contains debris, clean
thoroughly . If motor shaft cannot be turned,
remove mechanism.
