"F11" is a Serial Communications error between the Central Control Unit (CCU) and Motor Control Unit (MCU). The CCU is the main computer for the washer and is located directly behind the wash tub. The MCU is the Drive Motor Control board and is located in the rear of the washer adjacent to the Drive Motor on the left-hand side (facing from the rear with the back panel removed). The wiring harness can also cause the error, but it is not as common a problem.

Whirlpool is the manufacturer of both model washers and recommends the following troubleshooting advice. Remove the top panel of the washer by removing the three screws holding it in place in the rear. Once the screws are removed, the panel slides back, then off. Remove the rear panel of the washer for access to the drive motor and MCU. Now check the following:

- Check the wire harness connections between the CCU, the MCU and Drive Motor. Make sure all connections are attached and making good contact. Check for any broken wires or connector pins.
- Check the Drive Motor to see if it free spins and that the belt is still attached and not slipping. If the motor is seized, replace it. If the belt is broken or worn, replace it as well.
- Check the MCU. Connector 1 is the Serial Communications Link between the MCU and CCU. Connector 2 is the connector to the drive motor. Resistance checks across pins 1, 2, & 3 are the motor windings. Connector 3 is the power supply - 120VAC should be read across pins 1 and 2 with the door in the locked position. NOTE: The connectors are read 1, 2, and 3 from the bottom to the top with the MCU installed.
- Check the CCU. Verify connectors 7 and 11 are properly installed. Facing from the front of the washer, connector 7 is the 4th connector from the RIGHT along the front. This is MCU Power. Connector 11 is the Serial Communications link from the CCU to the MCU and is located along the left hand side of the CCU (the connectors are numbered 11 through 14 back to front).
- Check the Drive Motor. Remove the connector and perform resistance checks on the motor connector pins. Readings across pins 1 to 2, 2 to 3 and 1 to 3 should read 6 ohms.

In most cases this is an indication of a failed CCU. This is an easy repair that the average do-it-yourselfer can accomplish on their own. If the washer is still under a warranty, parts and labor would be covered. With no warranty, a replacement parts will vary in price depending on where you get them. There are several good websites available that you can order parts on line and have shipped directly to you.


NOTE: Remove all the connectors from the CCU ONE AT A TIME and reconnect to see if the error code goes away BEFORE you decide to purchase a new one. It is not common, but sometimes a flaky connection can generate error codes.

F11 flashing?


F11 is:
Serial Communication Error
Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.

Check for:
Check Wire Harness connectors to the MCU, the motor, and Central Control Unit (CCU)
Check the Drive system for any worn or failed components
Check MCU
Check CCU
Check Motor
Check Wire Harness

If all the connections look fine , then its possible the CCU is reading wrong and will need to be changed.

When trying to use the front load washer it flashes F11 and beeps an will not turn the washer on.


"F11" is a serial communications error between the Central Control Unit (CCU), the Motor Control Unit (MCU) and/or interconnecting wiring. The following link explains:

http://www.fixya.com/support/r666194-f11_error_whirpool_duet_kenmore_elite

The first step in troubleshooting this problem is to UNPLUG the washer for at least 30 minutes to reset the CCU. This is the main "brain" of your washer. Sometimes these error codes are erroneous and can be corrected by resetting the main computer. If the error code reappears following a CCU reset, then you have a legitimate problem. Read through the link and let me know if you have any questions. I hope this helps you.

Code F11 and the washer does not continue


"F11" is called a Serial Communications error. This commonly occurs when the Central Control Unit (CCU), which is the main computer, does not receive proper signals from the Motor Control Unit (MCU) for whatever reason. Before assuming you have a failed part, however, the manufacturer recommends unplugging the appliance for at least 30 miuntes to reset the CCU. Sometimes this is all that is required to correct momentary glitches. If the problem returns, review the following link for more information:

http://www.fixya.com/support/r666194-f11_error_whirpool_duet_kenmore_elite

In many cases this problem cures itself by resetting the computer. However, more commonly, when it appaears as a reoccuring problem, the CCU fails. Read through the link thoroughly, however, and follow the recommended advice just to be sure. Hopefully, this will not require any replacement parts. I hope this helps you. Let me know if you require further assistance.
