FAULT/ERROR CODES #1 — The fault codes below may be indicated
under various conditions and can be accessed through Service Diagnostics.
Display EXPLANATION AND RECOMMENDED PROCEDURE
Sud 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 problem, this may indicate:
Possible Causes
• Not using HE detergent or excessive detergent usage.
• Check/clean drain pump filter and hose of foreign objects.
• Ensure drain height does not exceed 8' (2.4 m) from washer base.
F0E1 (rl) LOAD DETECTED DURING THE WASHER CLEANING CYCLE (rl = remove load)
During the cleaning cycle, a load was detected inside the drum. Clear error code and run a Cleaning Cycle
to verify problem.
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 corrupted onboard EEPROM or communication error between the CCU and onboard EEPROM has
occurred. One of the main relays is not working properly.
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) on page 13.
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) on page 15.
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 dependent, but the procedure to detect this error does not change.
Possible Causes
• Check connections from tub to air trap, air trap to pressure hose, and pressure hose to pressure sensor.
Is pressure hose pinched, kinked, plugged, or leaking air?
• See TEST #7 (Pressure Sensor/Switch) on page 17.
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 on page 21.
Possible Causes
• See TEST #11 (Temperature Sensor) on page 21.
F4E0 HEATER IS NOT DETECTED
This error is generated when the CCU cannot detect the temperature rising during step C01 of the
Quick Diagnostic Test. This error code is available only in service diagnostics.
Possible Causes
• Heater element unplugged or open.
• See TEST #10 (Heating Element), page 20.
• See TEST #11 (Temperature Sensor), page 21.
