INDICATION DISPLAY
EXPLANATION AND RECOMMENDED PROCEDURE
PUMP DISCONNECTED
The electrical connection between the pump and the
CCU is lost.
Possible Causes
– Poor connection between CCU (DP2) and drain
pump.
– Pump thermal overload caused by the pump
running for an extended period of time.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Check electrical connection between pump and
CCU (DP2) (see page 14).
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.
LOAD DETECTED IN WASHER
DURING WASHER CLEANOUT CYCLE
The washer detects a load inside the washer tub
at the beginning of the Washer Cleanout Cycle.
Possible Causes
– Load inside the washer during the Washer
Cleanout Cycle.
– Friction between the drum and bellows material.
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
T bearing on the boot is not causing friction (which
is interpreted by the motor as a load in the washer).
If bellows adjustment does not correct the friction issue,
the spin basket will need to be replaced.
COMMUNICATION FAILURE
BETWEEN CCU AND UIC
Communication between Central Control Unit (CCU)
and User Interface Control (UIC) has failed.
Possible Cause
– Electrical connection between CCU and UIC
is damaged.
Procedure
1. Clear error code.
2. Unplug the washer or disconnect power.
3. Verify that the communication cable is connected
in the upper connector of the UIC.
4. Verify continuity in the cable between the CCU
and the UIC.
If, after these procedures, the continuity test fails,
replace the communication cable. If F70 is still
present, replace the UIC.

EXPLANATION AND RECOMMENDED PROCEDURE
DOOR UNLOCK ERROR
The door is unable to unlock after 6 tries.
Possible Causes
– Misaligned or broken door latch.
– Electrical connections from 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 14).
4. Make sure 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 14).
If the latch fails to unlock after checking all of the
above, replace the latch.
OVERHEATING OF MOTOR
The heat sink exceeds 212°F (100°C). If this condition
is met, the CCU resets the MCU, then waits for the
motor to cool down before restarting the motor.
This procedure can repeat up to 4 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.
