Customer Questions and Answers for Control Board by Whirlpool

HP, The issue with the OL to the pressure switch and the voltage to dispenser motor would be secondary to the F11. With getting power to the MCU but the motor not doing anything and the motor testing good, this would be a motor control failure. The part number for the motor control is W10756692.

Hello Doug! Yes, the motor control is also known as the electronic control, part number W10756692. Thanks.

Hello Ben, The F21 is the code for a long drain. For this code you need to check the pump area for debris and check the pump for normal operation. As per the tech sheet: If the drain time exceeds eight minutes, “F21” will be displayed, the water valves will turn off and the pump will stop running. Press PAUSE/CANCEL to drain the machine. The display will be cleared and the machine will turn off after a maximum of eight minutes. Possible Causes/Procedure - 1. Check the drain hose and make sure it is not plugged or kinked. 2. Unplug washer or disconnect power. 3. Check the electrical connections at the pump and make sure the pump is running. 4. Check the drain pump filter for foreign objects. 5. Plug in washer or reconnect power. 6. Unplug washer or disconnect power. 8. Replace the pump. The F28 is a serial communication error. The tech sheet instructs the following for this code: The communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly. Possible Causes/Procedure 1. Unplug washer or disconnect power. 2. Check wire harness connections to the MCU, the motor, and Central Control Unit (CCU). Check connections of the CCU board within the housing. Make sure all grounding switches are engaged. 3. Check the drive system for any worn or failed components. 4. Plug in washer or reconnect power. 5. Verify CCU operation by running a Diagnostic Test or any cycle. 6. Check the MCU by looking for operations of the drive motor. 7. Check the drive motor for powered rotations. 8. Check that the serial harness at the MCU is not mounted upside down. The wires should be to the left when facing the MCU connectors.

Lisa, The part number for the motor control of your unit is W10756692. To replace the bearing you would need to replace the rear outer tub W10772618 and the spider you would need the inner basket WPW10269756.

Hello John. The Motor Control Unit has internal failure. If failure occurs during high-speed spin the door unlocks after 3 minutes. This error code is only shown in Diagnostic test. Possible Causes/Procedure - Verify the shipping system including shipping bolts and spacers are removed, and power cord out of the unit. - 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. - Check all wire harness connections between the Motor & MCU, and MCU to CCU, are not broken or wires detached and connector internal pins are visible. - Make sure that all the connectors are fully seated. - Plug in washer or reconnect power cord. - Verify the unit operation by running the Diagnostic Test cycle. See page 5. - After the diagnostic test has finished, unplug washer or disconnect power cord and wait for 15 seconds.

Hello Paul, As per the tech sheet: This is a drive motor tachometer error. The control is unable to properly detect motor speed and the machine will shut down. If a failure occurs during high-speed spin, the door will be unlocked after three minutes. Possible Causes / Procedure 1. Verify the shipping system including shipping bolts, spacers and cables are removed. 2. Unplug washer or disconnect power. 3. Check wire harness connections between the drive motor and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU). 4. Plug in washer or reconnect power. 5. Check the MCU by looking for operations of the drive motor. 6. Check the drive motor for powered rotations. If you refer to page 13 of the tech sheet, the top left part of the wiring diagram, you will see the terminals labeled GND, In/Out, and Vcc. If there is a fuse on the board, you can check that with an ohm meter. If it is submerged in an epoxy type substance, the board will have to be replaced.

Michael, The F1 E2 error is a MCU Error with multiple resets. Motor Control Unit (MCU) has an internal malfunction, repeating under or over voltage, or over current conditions. Can also be caused by momentary loss of neutral feed to MCU during the spin cycle. If the error occurs during a high-speed spin, the door will remain locked for 3 minutes. TEST #3: Motor Circuit This test checks the motor, motor control unit (MCU), and wiring. IMPORTANT: A guide (W10271535) is required to assemble the rotor onto the shaft. The guide is inserted into the threaded hole, and then the rotor is slid on over the guide. NOTE: If the harness between the CCU and MCU is removed or communications are interrupted during operation, the MCU puts the motor into a braking mode, resulting in a significant drag on the drum when turned by hand. This mode can be cleared by removing power from the washer for a few seconds. 1. Check the motor and electrical connections by performing the “Quick Diagnostic Test” on page 6. The following steps assume that this step was unsuccessful. 2. Unplug washer or disconnect power. 3. Check to see if basket will turn freely. If basket turns freely, go to step 4. If basket does not turn freely, determine what is causing the mechanical friction or lockup. 4. Remove the top and rear panels to access the machine electronics and motor components. 5. Visually check that connectors MS2 and MI3 are inserted all the way into the CCU. If visual checks pass, go to step 6. If visual checks fail, reconnect MS2 and MI3, and repeat step 1. 6. Visually check that all connectors are inserted all the way into the MCU (see Figure 6, at left). If visual checks pass, go to step 7. If visual checks fail, reconnect the MCU connectors and repeat step 1. 7. Check the motor windings. Disconnect the motor harness from the MCU. With an ohmmeter, verify the resistance values as shown below: Motor Harness Winding Pin 1 & 3 8.5 - 14.0 ohms Pin 2 & 3 8.5 - 14.0 ohms Pin 1 & 2 8.5 - 14.0 ohms If the values are outside the range or open, replace stator assembly; otherwise, reconnect the motor harness and go to step 8. 8. Check the two harnesses between the CCU and MCU for continuity. If there is continuity, go to step 9. If there is no continuity, replace the main lower harness. 9. With a voltmeter set to AC, connect the leads across pins 1 and 2 of connector MS2. 10. Plug in washer or reconnect power.

Rose, With the issue that you are having with the F2 error code you will want to check the pressure hose to ensure that it is not clogged. Also check the connectors at the control board and at the drain pump for corrosion and if there is any corrosion then you would want to clean with a contact cleaner. Also check the hose that comes from the bottom of the tub to the drain pump for any debris that may be in it. Clear any out if found. If all this checks ok then the main control board WP8182695 would be the most likely issue.

Hello Dave. Yes, here is a link to our return policy. http://www.appliancepartspros.com/customerservice/returns.aspx

Hello Dave. Per the manufacturer • Check wire harness connections between the Drive Motor/Tachometer and the Motor ControlUnit (MCU), and between the MCU and the Central Control Unit (CCU) • Check the Drive Motor • Check the MCU • Check the Wire Harness If harness is good then the mcu will probably be the issue.
