FAULT/ERROR CODES #2 — The fault codes below may be indicated
under various conditions and can be accessed through Service Diagnostics.
Display EXPLANATION AND RECOMMENDED PROCEDURE
F5E1 DOOR SWITCH ERROR
This code is generated if the door has not been open for 3 consecutive cycles, or the door switch is open
while the door is locked for more than 5 seconds. If this occurs during normal operation, the buzzer beeps
3 times. This error code is available only in service diagnostics.
Possible Causes
• User presses START without closing door.
• Door not open for 3 consecutive cycles.
• Door switch mechanism damaged or obstructed.
• See TEST #4 (Door Lock System) on page 16.
F5E2 DOOR LOCK ERROR
At the start of a cycle, the washer attempts to lock the door 6 times. If door cannot be locked, the washer
goes into pause mode and a code is generated. This code is available only in service mode.
Possible Causes
• Door not completely closed due to interference.
• Check door lock mechanism for damage, misalignment, or foreign objects.
• See TEST #4 (Door Lock System) on page 16.
F5E3 DOOR UNLOCK ERROR
At the start of a cycle, the washer attempts to unlock the door 6 times. If door cannot be unlocked, the washer
goes into pause mode and a code is generated. This code is available only in service diagnostics.
Possible Causes
• Verify door latch is secured to front panel.
• Check for misaligned, broken, or over-tightened door latch.
• See TEST #4 (Door Lock System) on page 16.
F6E1 COMMUNICATION ERROR BETWEEN CCU AND MCU
Communication between the Central Control Unit and the MCU has not been detected.
Possible Causes
• Check door switch operation. Faulty switch may interfere with power to MCU.
• Check drive system for worn or faulty components.
• Verify continuity in cable between CCU (MI3 & MS2) and MCU. See wiring diagrams on pages 23–24.
• See TEST #1 (CCU Power Check) on page 13.
• See TEST #3 (Motor Circuit) on page 15.
F6E2 COMMUNICATION ERROR UI TO CCU
F6E3 COMMUNICATION ERROR CCU TO UI
Communication between Central Control Unit (CCU) and User Interface (UI) has not been detected.
Possible Causes
• Verify continuity in cable between CCU (UI7) and UI (C2). See wiring diagrams on pages 23–24.
• Check AC and DC supplies. See TEST #1 (CCU Power Check) on page 13.
• See TEST #2 (User Interface) on page 14.
F7E1 DRIVE MOTOR SPEED SENSING ERROR / WASHER OVERLOAD
The MCU is unable to properly detect motor speed and the washer shuts down. If error occurs during
high-spin, the door remains locked for 2–3 minutes.
Possible Causes
• Washer is overloaded.
• Verify that the shipping system, including shipping bolts and spacers, is removed.
• Mechanical friction – verify that drum rotates freely.
• See TEST #3 (Motor Circuit) on page 15.
F7E2 MCU OVERHEAT AND/OR MOTOR OVERHEAT
The heat sink exceeds 212°F (100°C). If this occurs, the CCU will reset the MCU and wait for the motor
and/or the MCU to cool down before restarting. After 4 attempts, F7E2 is displayed.
Possible Causes
• Improper installation of washer. Ensure that washer is not located near a heat source and has proper ventilation.
• Check that drum is not overloaded with clothes.
• Mechanical friction – verify that drum rotates freely.
• Check drive system for worn or faulty components. See TEST #3 (Motor Circuit) on page 15.
DO NOT REMOVE OR DESTROY
