Customer Questions and Answers for Electronic Control Board (Central Control Unit) by Whirlpool

It could be the CCU. I would take a close look at my gearcase(transmission), clutch, belts, and bearings. If present on your machine (no model number provided). These could be likely cause for the issue as well. But first I would locate the tech sheet that is inside the washer and run a diagnostics mode and see if it will give you any codes to direct your repair process .

Mike, Check to see if there is power getting to the drain motor when it should drain. If there is power and the pump is not working then the pump is faulty and would need to be replaced. If the pump is not getting 120 Vac then the board would be faulty and need to be replaced.

Jimmy, This is what I found for your error: F9E2 - When the connection between the pump and the Central Control Unit (CCU) is lost during cycle drain. Cause/Solution - Make sure that all wire harness connections at the Drain Pump & CCU (DP2 cavity) connectors are not broken or with wires detached, and that connector internal pins are visible. - Check continuity from the Drain Pump & CCU (DP2 cavity) connectors. - If the continuity diagnosis failed, the Main Harness must be replaced. Check the resistance of the motor pump. - If the above does not correct the problem, - check the drain pump filter for foreign objects. - Disassemble the drain pump from the washer. - Check that the impeller is not detached from the motor shaft. If the impeller is detached from the shaft, is broken, or has any scratches, the drain pump must be replaced.

Hello Lynda, Start by turning off power to the washer, disconnect the water fill hoses and drain hose if needed. Access the rear of the washer and remove the 3 T-20 screws from the top cover, pull the cover rearward and release the tabs in the console from the slots in the cover, then lift off the cover. The main control board is mounted in the front on right side near the top. The control will slide to the rear once you pry the locking tab outward slightly.

Moe, The first thing to check would be the wiring between the main board and the motor control unit. Test the wiring for continuity and loose or corroded connections. If this checks ok then the issue will be a bad Main control board.

Hello Larry, The fault code you got is indicating a SERIAL COMMUNICATION ERROR. The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly. As per the tech sheet: Possible Causes/Procedure - Unplug washer or disconnect power. - Check that the power cord terminals are connected at the right position to the RFI filter (white-Neutral/ black-Line). - Make sure that the two ground switches are pressed correctly by the toe and rear panels. - Make sure that ground switches are installed correctly, are not broken, and that the green ground wires are connected correctly. - Make sure that both ground switches are not broken or scratched. - Make sure that all the ground harnesses (green wires) are connected correctly, and are not broken or with wires detached. - Make sure that all wire harness connections from the CCU (MI3 cavity), main Motor, and MCU are not broken or with wires detached, and that connector internal pins are visible. - Check for continuity from the MCU connector wires to CCU (MI3 cavity) connector. - If the continuity diagnosis failed, the Main Harness must be replaced. - Make sure that all the connectors are fully seated. - Check the drive system for any worn or failed components. - Plug in washer or reconnect power. - Verify the washer operation by running the Diagnostic Test cycle. See page 5. - After the diagnostic test has finished, unplug washer or disconnect power and wait for 15 seconds.

Georgio, With the unit not doing anything when it comes to the diagnostics, the issue will be with the CCU which is part number WPW10491312.

Don, The CCU would most likely not be the issue with the unit but the MCU would. This is the motor control unit and the error represents a internal failure of the MCU. If all of the following checks ok then the MCU would need to be replaced. Possible Causes/Procedure - Verify the shipping system, including shipping bolts and spacers, are removed, and that power cord is out of the washer. - Check if washer is on a dedicated circuit. Other devices on same circuit can create line noise and cause this issue. - Unplug washer or disconnect power. - Check the neutral feed to the MCU and CCU from the AC line filter. - Make sure all wire harness connections between the Motor & MCU, and MCU to CCU, are not broken or with wires detached, and that connector internal pins are visible. - Make sure that all the connectors are fully seated. - Plug in washer or reconnect power. - Verify the washer operation by running the Diagnostic Test cycle. - After the diagnostic test has finished, unplug washer or disconnect power and wait for 15 second

Steve, There is a thermistor in the unit which you will want to test to make sure that it is not faulty. The thermistor part number is WPW10467289 and the tech sheet will give you resistance values of this thermistors.

Hello Harlan. If the water temperature sensor (NTC) value is out of range (23°F to 217°F [-5°C to 103°C]) during the water-heating step of the WASH cycle. Possible Causes/Procedure - Unplug washer or disconnect power. - Make sure that connections to water heater & CCU (TH2 & HE2 cavities) connectors are not broken or with wires detached, and that connector internal pins are visible. - Check continuity from the water heater sensor (black wires) to CCU (TH2 cavity) connector. - If the continuity diagnosis failed, the Main Harness must be replaced. - Check the resistance of heating element. - Check the resistance of the water sensor. - Plug in washer or reconnect power. - Verify the washer operation by running the Diagnostic Test cycle. - After the diagnostic test has finished, unplug washer or disconnect power and wait for 15 seconds.
