Failure
Explanation and Recommended Procedure
Fault is displayed if any of the following conditions occur:
• Lid is not closed completely due to interference.
• Check for lock interference with lid or lock bezel.
• Wash media buildup is preventing the lock bolt from extending.
• Main control detects open lid switch when attempting to lock.
• Main control cannot determine if lid lock is in a locked state.
• See TEST #8: Lid Lock, page 20.
Fault is displayed when one of the following conditions occurs:
• Excessive force on lid is preventing lock bolt from retracting.
• Wash media buildup is preventing lock bolt from retracting.
• Main control cannot determine if lid lock is in an unlocked state.
• See TEST #8: Lid Lock, page 20.
Fault is displayed when one of the following conditions occurs:
• User presses START with lid open.
• User presses START after a predetermined number of consecutive
washer cycles without opening lid.
• The main control cannot detect the lid switch opening and closing properly.
• See TEST #8: Lid Lock, page 20.
Fault is displayed when communication between the UI and the ACU
has not been detected.
• Check continuity in the UI harness.
• Complete Test #1: Main Control (ACU), page 14 and Test #4:
Keys and Encoders, page 17.
Fault is displayed when the main control detects control voltage
is too low or lost.
• Check power at outlet.
• Check circuit breakers, fuses, or junction box connections.
• Check AC power cord for continuity.
• See TEST #1: Main Control (ACU), page 14.
Fault is displayed when power is lost during spin. This fault forces
the washer to pause for 5 minutes to allow the basket to stop before
continuing the cycle.
• See F7E0 recommendations above.
Fault occurs when the main control detects a problem in the
motor drive. See TEST #3b: Drive System – Motor, page 16.
Fault is displayed when the main control determines the shifter
is not engaging the basket for spin or disengaging it for wash.
• Check shifter connectors.
• Check for clothing or another item wedged between the impeller
and the basket that could bind them together.
• Check that the shifter slider moves freely.
• See TEST #3a: Drive System – Shifter, page 15.
Fault is displayed when main control detects one or more of the motor
lines is open.
• Check motor circuit.
• See TEST #3: Drive System, page 15 or TEST #3b: Drive System –
Motor, page 16.
Fault is displayed when the main control is unable to get to the
commanded motor speed.
• Mechanical friction on drive mechanism or basket (items
between basket and tub).
• Load off balance. Items should be distributed evenly when loading.
• See TEST #3: Drive System, page 15 or TEST #3b: Drive System –
Motor, page 16.
