Customer Questions and Answers for Electronic Control Board by Whirlpool

Ken,

The F29 error will indicate a door unlock error. This issue will most likely be a door lock mechanism that is broken.

Michael,

For this issue, with the door lock having already been replaced then this will be a control board issue and will be part number WP8183258.

Hello Juan. When the dispenser motor cannot be driven to its proper
position. 1. Unplug washer or disconnect power.
2. Check mechanical linkage from dispenser motor to the top
of the dispenser.
3. Check wire harness connections to the dispenser motor
and Central Control Unit (CCU).
4. Check dispenser motor for powered rotations.

Eric, The F71 error code indicates a communication error between the User Interface (U/I and the Central Control Unit (CCU). " If a Central Control Unit Heartbeat Failure is displayed, no communication is detected from the User Interface to the Central Control Unit. Possible Causes/Procedure Check for continuity of the User Interface harness.
Check wire harness connections to the User Interface and the Central Control Unit. Replace User Interface if drum is rotating. Replace Central Control Unit if drum is not moving."
You may want to remove power to the washer, remove the top panel and access the harness(s) at the CCU and user interface, disconnect the connectors and clean the contacts with rubbing alcohol or electrical contact cleaner. Reconnect the connectors and check to make sure they fit tight. And go from there.

Hello Debbie,
This can be the filter WPW10367632, the door latch switch assembly WP8183270, the pressure switch WPW10514214, or the control WP8183258. You will need to test for where the power stops with a test meter to determine the failed component.

Hello Jim. See if the clicking sound is coming from the door lock assembly. If so, you will need to replace the door lock assembly from the unit. If not, then it could be the main board on the unit failing. By unplugging the unit, you are resetting the board so it will run through the cycle.

Hello Susan. The Motor Control Unit has internal failure; repeating under or
over voltage, or over current conditions. If failure occurs during
high-speed spin the door unlocks after 3 minutes. Possible Causes/Procedure
1. Unplug washer or disconnect power.
2. Check wire harness connections between the drive motor and the
Motor Control Unit (MCU), and between the MCU and the Central
Control Unit (CCU). Check the motor and do a continuity test.
3. Plug in washer or reconnect power.
4. Check the MCU by looking for operations of the drive motor.
5. Check the drive motor for powered rotations.
6. Replace MCU board.

John,

You will want to make sure that you have power going to the CCU. There should be 120 vac on connector IF2 between pins one and 2. If there is power there then most likely you will need to have a new CCU. If there is no power then the Line filter is bad and would need to be replaced.

Lloyd, Since you have the tech sheet, you know the F28 error code indicates a communication error between the CCU and the MCU. Check and make sure there are no loose connections at the MCU and motor. For the diagnostics program, Unplug the power cord, and press each button individually, make sure there is not a stuck or weak button tab. Then re plug the power cord into the outlet and follow the programming instructions closely ( press and hold four seconds means four seconds).

Hello Steve,

Based on the information provided it sounds like it is the CCU WP8183258 that needs to be replaced.
