PROBLEM
Will not fill or water level
low. The Check Drain LED
is flashing.
Wash pump will not pump.
POSSIBLE CAUSE
1. No water to dishwasher.
2. Loose connection to dish-
washer fill valve or in the valve
circuit.
3. Pressure switch stuck in "over-
fill" position.
4. Open coil on fill valve solenoid.
5. Drain stopper not in place or
not secured properly.
6. Inlet screen on fill valve
plugged.
7. Faulty fill valve drive circuit on
the control.
8. Customer perception of proper
water level incorrect.
9. Drain stopper not sealing.
1. Pump motor seized up (will not
turn).
2. Loose harness connection in
pump motor circuit.
3. Damaged wash pump motor
capacitor.
4. Pump motor winding opened.
5. Faulty wash pump drive circuit
on the control.

SOLUTION
1. Verify the water is turned On and the
supply line adequate. Correct installation
as necessary.
2. Check resistances of all harness con-
nections between the fill valve and the
control.
3. Verify that pressure switch contact 21 &
22 are "closed." Disconnect the harness
leads from the pressure switch. If there
is an open circuit across 21 & 22, re-
place pressure switch.
4. Disconnect the harness leads from the
water inlet valve and measure the resis-
tance of the valve coil.
5. Instruct the customer on the drain stop-
per installation, refer to Use and Care
Guide.
6. Disconnect the water line to fill valve and
inspect the inlet for obstructions.
7. Check operation of the fill valve by the
control during Diagnostics.
8. Customer Instruct - normal water level is
just above bottom of tub.
9. Engage drain stopper. Run water into
the dishwasher. If water drains out of the
dishwasher, replace the stopper.
1. Remove the pump motor housing. Verify
the rotation of the motor shaft by rotating
the impeller. Rotation should only require
a moderate force. If the rotation is diffi-
cult or not possible, replace the pump &
motor assembly.
2. Check the resistances of all connections
between the pump motor and the con-
trol, particularly the pump motor to its
capacitor.
3. Disconnect the capacitor leads and con-
firm that the capacitance is as labeled on
part. Also check the resistance for an
open circuit across the terminals. Re-
place if open.
4. Disconnect all leads and check the resis-
tance of the windings.
5. Check the operation of the wash pump
motor by the control during Diagnostics.
