PROBLEM POSSIBLE CAUSE /TEST
NOTE: Possible Causes/Tests must be performed in the sequence show for each problem.
GARMENT IS WET 1. Disconnect the fan motor and verify that there is voltage of 120V at the fan motor connector on the
harness during the running/drying mode. If there is voltage, go to step 5.
2 If there is no voltage at the fan motor connector on the harness, check the continuity between fan
motor connector terminal 1 and CON1-P11 and also between fan motor connector terminal 2 and
CON1-P9.
3. Replace the harness if there is no continuity in any line.
4. Replace the ACU if the harness is OK and if voltage was not found at the fan motor connector on the
harness in step 1.
5. If there is voltage at the fan motor connector on the harness, replace the fan motor.
THERE IS A PUDDLE OF
WATER BENEATH THE
SWASH™ SYSTEM
1. Empty the reservoir tray.
2. Disconnect the reservoir sensor switch.
3. Check the continuity (J3-3 to J3-4) in the reservoir sensor switch connector to the SWASH™system
when the reservoir tray is inserted. If there is continuity, go to step 5.
4. If there is no continuity, replace the reservoir sensor switch.
5. Check the continuity in the harness between reservoir sensor switch connector terminal 1 and
CON3-P4 and also between sensor switch connector terminal 2 and CON3-P3.
6. Replace the harness if there is no continuity in any line.
7. If none of these steps indicate an electrical problem, the problem is mechanical and the reservoir tray
must be replaced.
CUP IS NOT COMPLETELY
EMPTY
1. Verify that the piercing mechanism is properly piercing the cup.
2. Remove the needle and make sure that liquid can pass through it.
3. Inspect the hoses to verify that they are not kinked.
4. Replace the pump.
SWASH™ SYSTEM STARTS
BY ITSELF
1. Check for an error code on the SWASH™ system display.
2. Verify that there is voltage of 5V DC between pin 2 and pin 3 at connector P19 on the ACU.
3. If there is no voltage between pin 2 and pin 3 at connector P19 on the ACU, replace the ACU.
4. If there is voltage between pin 2 and pin 3 at connector P19 on the ACU, replace the UI.
SWASH™ SYSTEM VIBRATES
OR IS NOISY
1. Verify that the pump is properly attached.
2. Make sure that the impeller is not touching the lower blower.
3. Verify that the motor is properly attached.
4. Verify that the motor shaft is not damaged.
