FAULT/ERROR CODES (continued) — See page to access Fault Code Display Mode
DESCRIPTION
Explanation & Recommended Procedure
LID UNLOCK FAULT
Fault is displayed if Lid Lock has not moved into unlocked position or motor cannot be powered.
• Check for lock interference with lock striker.
• Main control cannot determine if lid lock is in an unlocked state.
• See TEST #8: Lid Lock.
LID NOT OPENED BETWEEN CYCLES
Fault is displayed if the following conditions occur:
• User presses START after several consecutive washer cycles without opening lid.
• See TEST #8: Lid Lock.
BASKET SPEED SENSOR FAULT
Fault is displayed when the main control cannot determine speed of basket.
• Locked rotor—check that basket, impeller, and motor can rotate freely.
• Check harness connections from main control to motor and shifter.
• See TEST #3a: Drive System–Shifter.
SHIFTER FAULT
Fault is displayed when the main control cannot determine position of shifter.
• Check harness connections from main control to motor and shifter.
• Observe shifter operation.
• See TEST #3a: Drive System–Shifter.
MOTOR FAULT
Indicates an open clockwise or counterclockwise circuit of the motor.
• See TEST #3b: Drive System–Motor.
MOTOR UNABLE TO REACH TARGET RPM
Fault is displayed when basket speed sensor detects that target RPM was not reached.
• Mechanical friction on drive mechanism or basket (clothing between basket and tub).
• Weak motor or run capacitor.
• Load off balance. Clothing should be distributed evenly when loading.
• See TEST #3b: Drive System–Motor.
NO FILL, LONG FILL
Fault is displayed when the water level does not change for a period of time OR water is present but main control
does not detect the water level changing.
• Is water supply connected and turned on?
• Low water pressure; fill times longer than six minutes. Are hose screens plugged?
• Check for proper drain hose installation. Is water siphoning out of the drain hose?
• Drain hose must not be more then 4.5" (113mm) into the drain pipe.
• Check pressure hose connection from tub to main control. Is hose pinched, kinked, plugged, or leaking air?
• See TEST #2: Valves.
OVERFLOW CONDITION
Fault is displayed when main control senses water level that exceeds the washer's capacity.
• May signify problem with inlet water valves.
• Check pressure hose connection from tub to main control. Is hose pinched, kinked, plugged, or leaking air?
• Pressure transducer fault on main control.
• See TEST #2: Valves and
HOT, COLD REVERSED
Fault is displayed when the hot and cold inlet hoses are reversed.
• Make sure inlet hoses are connected correctly.
• If hoses are installed properly, temperature thermistor may be stuck in low resistance range.
• See TEST #2: Valves and
LONG DRAIN
Fault is displayed when the water level does not change after the drain pump is on for 10 minutes.
• Is the drain hose or the drain pump clogged? Check tub sump under impeller for obstructions.
• Is the drain hose height greater than 96"?
• Check pressure hose connection from tub to main control. Is hose pinched, kinked, plugged, or leaking air?
• Is the pump running? If not, see TEST #7: Drain Pump.
* If the Sensing LED is ON, the fault code number is represented; if OFF, the error code number is represented.
