Customer Questions and Answers for Electronic Control Board (Cntrl-Elec) by Whirlpool

Dave, " Manually Unlocking the Door Lock System 1. Unplug washer or disconnect power. 2. Remove the lower kick panel. 3. Reach up along the inside of the front and locate the bottom of the door switch/lock unit. 4. Located on the bottom of the door switch/lock unit is a tear-drop shaped tab. 5. Gently pull the tab down about a ¼" or until a click is heard. 6. The door may be opened." The F28 error cod indicates a communication failure between the CCU(main control board) and the MCU(motor control board) in the bottom of the cabinet. You'll need to remove the top panel and check the connections at the CCU and check the wire harness and connections between the CCU and the MCU. While you have the lower access panel off, if the tech data sheet is there, you can run the diagnostics test and error codes, it may assist you in the repair and diagnostics and give you an idea of what or where the problem is.
