ERROR NUMBER

FAULT NUMBER

Fault is displayed if lid is in locked state, but lid switch is open.

• User presses START with lid open.

• The main control cannot detect the lid switch opening and closing properly.

• See TEST #8: Lid Lock, page 18.

Fault is displayed when the Inlet Thermistor is detected to be open or shorted.

• See TEST #5: Temperature Thermistor, page 17.

Fault is displayed when the Main Control detects an out of range pressure signal.

• Check pressure hose connection from tub to main control. Is hose pinched, kinked, plugged, or leaking air?

• See TEST #6: Water Level, page 17.

The User Interface identification does not match the expected value in the Main Control Board. 

• Fault occurs during Diagnostic Test Mode if a mismatch of main control and UI is identified.

• See TEST #4: Consoles and Indicators, page 16.

Explanation & Recommended Procedure

(Status LED names may vary between makes and models)

One or more keys on the User Interface were actuated for 15 consecutive seconds. 

• Fault occurs during Diagnostic Test Mode if a stuck key is detected.

• See TEST #4: Consoles and Indicators, page 16.

Status LEDs

DISPLA

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. 

• Excessive detergent usage.

• Check pressure hose connection from tub to main control. Is hose pinched, kinked, plugged, or leaking air?

• Mechanical friction on drive mechanism or basket. (Clothing between basket and tub.)

Indicates a fault of the motor control section of the main control.

• See TEST #3b: Drive System – Motor, page 14.

Indicates a main control fault.

• See TEST #1: Main Control, page 12.

Fault is displayed when an off balance condition is detected. 

• Check for weak suspension. Basket should not bounce up and down more than once when pushed.

• Clothing should be distributed evenly when loading.

Fault is displayed when washer detects water temperature 105° or higher during rinse cycle. 

• Hot water getting in. Make sure inlet hoses are connected correctly.

• See TEST #5: Temperature Thermistor, page 17.

• If hoses are installed properly, temperature thermistor may be stuck in low resistance range.

LID LOCK FAULT

e2

Fault is displayed if Lid Lock has not moved into locked position or motor cannot be powered.

• Lid is not closed completely due to interference.

• Check for lock interference with lock striker.

• Wash media buildup (detergent, lint, etc.) is preventing the lock mechanism from sliding.

• Main control detects open lid switch when attempting to lock.

• Main control cannot determine if lid lock is in a locked state.

• See TEST #8: Lid Lock, page 18.
