FOR SERVICE TECHNICIAN'S USE ONLY
FAULT/ERROR CODES #1 — The fault codes below may be indicated under various
conditions and can be accessed through Service Diagnostics.
Code 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:
• Not using HE detergent or excessive detergent usage.
• Verify 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.
F0E1 LOAD DETECTED DURING THE WASHER CLEANING CYCLE (remove load)
During the cleaning cycle, a load was detected inside the drum. Clear error code and run a Cleaning
Cycle to verify problem.
• Load inside the washer during clean cycle.
• Mechanical friction on drive mechanism or basket. (Clothing between basket and tub.)
F1E1 CENTRAL CONTROL UNIT (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.
• 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 MOTOR CONTROL UNIT (MCU) ERROR - MULTIPLE RESETS
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.
• See TEST #3 (Motor Circuit) on page 15.
F2E2 USER INTERFACE (UI) SOFTWARE ERROR 1
Appears if UI software is corrupt.
• Check harness and connections between the CCU and UI. Recycle power and retest.
• If harness and connections between the CCU and UI are good, replace UI.
F2E3 UNSUPPORTED CYCLE
Cycle corruption or CCU is not compatible for this specific model of washer.
• Intermittent communication between CCU and UI. Check harness for continuity.
• Rotate cycle selector knob and verify cycle information on LCD screen. CCU may be corrupted.
• CCU is not compatible with washer—replace CCU.
F3E1 PRESSURE SENSOR ERROR
The CCU detects an out of range pressure signal.
• 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) 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 20.
• See TEST #11 (Temperature Sensor) on page 19.
F3E4 LEVEL OR PRESENCE SENSOR ERROR
The level/presence sensor is not able to detect presence of the cartridge or level of the detergent.
This error code does not stop the washer from functioning and is available only in service diagnostics.
• See TEST #15 (Level/Presence Sensor Module) on page 22.
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.
• Heater element unplugged or open.
• See TEST #10 (Heating Element), page 19.
• See TEST #11 (Temperature Sensor), page 19.
