Display EXPLANATION AND RECOMMENDED PROCEDURE
SUDS SUDS DETECTED
Fault is displayed when Suds prevent the basket from spinning up to speed or the pressure sensor detects
rising suds level. The main control will flush water in attempt to clear Suds. If the water flush is unable to
correct the

indicate:
Possible Causes
• Not using HE detergent or excessive detergent usage.
• Verify Bulk Dispensing setting. Make sure user has selected the right type of detergent and water hardness.
• Check/clean drain pump filter and hose of foreign objects.
• Ensure drain height does not exceed 8' (2.4 m) from washer base.
F0E1 LOAD DETECTED DURING THE WASHER CLEANING CYCLE
During the cleaning cycle, a load was detected inside the drum. Clear error code and run a Cleaning Cycle
to verif
y
p
roblem.
Possible Causes
• Load inside the washer during clean cycle.
• Mechanical friction on drive mechanism or basket. (Clothing between basket and tub.)
F1E1 CCU ERROR
A communication error between the CCU and onboard EEPROM has occurred, or one of the main relays is
not workin
g
p
ro

erl
y
.
Possible Causes
• Check the electrical outlet for damage.
• A power surge/drop may have caused this problem. Unplug or disconnect washer. Verify power at outlet
(voltage, polarity, grounding, and dedicated circuit). Reconnect power and retest.
• A relay on the CCU may be welded.
See TEST #1 (CCU/Power Check).
F1E2 MCU ERROR - MULTIPLE RESETS
Motor Control Unit (MCU) has an internal malfunction, repeating under or over voltage, or over current
conditions. Can also be caused by momentary loss of neutral feed to MCU during the spin cycle. If the
error occurs during a high-speed spin, the door will remain locked for 3 minutes.
Possible Causes
• See TEST #3 (Motor Circuit).
F2E3 UNSUPPORTED CYCLE
Cycle corruption or CCU is not compatible for this specific model of washer.
Possible Causes
• Intermittent communication between CCU and UI. Check harness for continuity.
• Rotate cycle selector knob and verify cycle information on console. CCU may be corrupted.
• CCU is not compatible with washer—replace CCU.
F3E1 PRESSURE SWITCH / PRESSURE SENSOR ERROR
The CCU detects an out of range pressure signal. The use of analog pressure sensor or digital pressure
switch is model de
p
endent, but the
p
rocedure to detect this error does not chan
g
e.
Possible Causes
• Check pressure hose connection from tub to pressure sensor. Is hose pinched, kinked, plugged, or leaking air?
• See TEST #7 (Pressure Sensor/Switch).
F3E2 TEMPERATURE SENSOR ERROR
This error is displayed if the water temperature sensor value is out of range (23°F to 217°F [–5°C to 103°C]).
To find the correct ohm reading, refer to temperature chart. This error code is available only in
service
g
nostics.
Possible Causes
• See TEST #11 (Temperature Sensor).
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).
