DOOR UNLOCK ERROR
The door is unable to unlock after six tries.
Possible Causes
– Misaligned or broken door latch.
– Electrical connections from washer CCU
(DLS2, DL3) to door lock are damaged.
– Misaligned, broken, or overtightened door hook.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Manually unlock the door (page 16).
4. Ensure that the latch is secured to the front panel.
5. Check for misaligned, broken, cracked, or loose
door hook.
6. Check the electrical connections between CCU
(DLS2, DL3) and latch (see page 16).
If the latch fails to unlock after checking all of the
above, replace the latch.

OVERHEATING OF MOTOR
The heat sink exceeds 100°C (212°F). If this condition
is met, the washer CCU resets the MCU, then waits
for the motor to cool down before restarting the motor.
This procedure can repeat up to four times before F31
is displayed.
Possible Causes
– Improper installation of washer.
– Poor electrical connection from CCU (MS2) to MCU.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Verify the washer is not located near a source
of heat and has proper ventilation.
4. Check the electrical connections between CCU
(MS2) and MCU.
5. Verify the drive motor operation in diagnostic mode.
If, after the above tests, the motor overheats, replace
the MCU.

PUMP DISCONNECTED
The electrical connection between the pump
and the washer CCU is lost.
Possible Causes
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Check electrical connection between pump
4. Check the pump using a diagnostic mode.
If all of the above are OK and the pump still does
not run, replace the CCU.

Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Remove clothes from washer drum.
4. Verify that misalignment of the spin basket and the
If bellows adjustment does not correct the friction issue,
the spin basket will need to be replaced.

COMMUNICATION FAILURE
BETWEEN WASHER CCU AND UIC
Communication between washer Central Control Unit
(CCU) and User Interface Control (UIC) has failed.
Possible Causes
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Verify that the communication cable is connected
4. Verify continuity in the cable between the CCU
If, after these procedures, the continuity test fails,
replace the communication cable. If F70 is still
present, replace the UI control.

T bearing on the boot is not causing friction (which
is interpreted by the motor as a load in the washer).
