"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.

The "F" variables (F4-F16) are for electrical problems. You should select Pause/Cancel twice then select Drain/Spin if there is excessive water in the washer. Re-select cycle and press start. According to the manual, if the problem remains, call for service.

I found that the vibration of the machine caused the relays in the motor control to malfunction causing the code to be thrown. It has happened many times to my machine and was always during or shortly after the spin cycle. I took the top cover off the machine and hung the motor control with wire zip ties so it was allowed to "float". I have done at least a hundred loads since, without a problem. I recommend someone to try this if their machine is out of warrenty before calling in a service tech.

First, attempt to unplug the washer for AT LEAST 30 minutes in an attempt to reset the Central Control Unit (CCU). In many cases, this is all that is required in order to correct momentary glitches with the unit. If the error code reappears, follow the advice provided in the link. In the majority of the cases, I've experienced, it was the CCU that caused the problem.
If you have questions, or require additional assistance, please let me know. I hope this helps you.
