Error Codes
(Continued Next Page)
Error Code Description Action
E1 UI EEPROM
E2 Power EEPROM Internal problem with
UI or MC board • Replace board as necessary.
E4 Thermistor
Short
E5 Thermistor
Open
Water Temperature
Sensor Problem • Check integrity of wiring and connections between main
control and Thermistor Assembly.
• Using ohmmeter, measure Thermistor resistance. If outside
expected range, replace Thermistor Assembly.
IF ABOVE STEPS DO NOT CLEAR THE PROBLEM:
• Replace the main control.
E6 Pressure
Switch Water Level Sensor
Problem • Check integrity of wiring and connections between main
control and Water Level Sensor.
• Check integrity of Water Level Sensor; replace if necessary.
• Check drain system.
IF ABOVE STEPS DO NOT CLEAR THE PROBLEM:
• Replace the main control.
E7 Slow Fill Fill Problem • Ensure manual water valves are fully open.
• Check if water strainers on solenoid valve assembly are
clogged.
• Check for obstructions inside inlet water hoses.
• Ensure solenoid valves do not leak when the valves are de-
energized and the washer is powered down.
• Measure coil resistance for both valves. If outside range
(1000–1250 ohms at room temp), replace solenoid valve
assembly.
IF ABOVE STEPS DO NOT CLEAR THE PROBLEM:
• Replace solenoid valve assembly.
E8 Drain System Drain Problem • Ensure pump strainer is clean and free of debris.
• Check for obstruction inside the drain hose.
• Check pump impeller blades and bearing; if evidence of
blade damage or seized bearings are present, replace the
pump.
• Check the electrical connections at the pump motor and
harness.
• Measure pump motor resistance. If outside range (9–14
ohms at room temp), replace the pump.
E9 Dispenser
Motor Dispenser Problem • Check for obstruction in dispenser mechanism and
linkages.
• Check the electrical connections at the motor feedback
switch and in the harness.
• Check the electrical connections of water valves in the
harness.
IF ABOVE STEPS DO NOT CLEAR THE PROBLEM:
• Replace dispenser motor assembly.
Note: It’s important to note error codes should only be used to help identify components which require
testing. Never replace a part based solely on an error code. The control can generate a false error if the
right conditions exist. Use the code only as a reference and always check the component before replacing.
