"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.

    Flashing F 11, drum spins by hand.unplugged for 30 sec and plugged back in started to fill then stopped .flashed F11 again


    The F11 error can be difficult to resolve even for us technician's.

    The F11 error occurs when the central control and motor control don't talk to each other.

    If one of the controls was actually bad then I'd expect to see the error code every cycle. If it does, start by checking all the wiring connections from the panel to the CCU. Post back your results.

    Error code F11 washer stops mid-cycle


    Hi,

    The F11 code means that communication between the CCU circuit board at the top of the machine and the motor control circuit board at the bottom of the machine has been lost. The problem most often found is cold solder joints on the CCU board that make and break causing the F11 code and sometimes an FdL code. To fix this you need to remove the CCU circuit board at the top of the machine and have the larger solder points of the relays and the spade connectors resoldered. If your not to handy with soldering you could just print out this response and a good appliance repair shop should be able to help you out. Good Luck.

    Stops on spin cycle and gives a f11 error code


    F11 is a serial communication error. Communication between the main board and the motor control board is not being sent correctly. This could be a bad main board, motor control board or motor itself. The testing can get pretty involved. Try putting the machine in a self test mode and see if the error clears. Press Cancel, then by pressing the drain spin button once on the left side then move to the spin speed button the the right. Press this button until no-spin lights. Press the prewash button 4 times. C00 should appear in the display. Let it run it's tests, there will be 8 of them and end up on C08. If this doesn't work, it's best you wait for the service tech.

    Hotpoint wt741 f11 what does this mean


    Hotpoint Error Codes.



    Hotpoint washing machines are among the most common found in the Uk and like any mechanical device they will occasionally breakdown or develop a fault and need repairs.
    Being a very popular make means that most parts supplier will keep there parts in stock and because so many suppliers keep Hotpoint parts stock this also drives competition hence driving down the price of parts if you should ever need them

    One problem many people including some engineers face when faced with a faulty Hotpoint washer is knowing what the error code mean, so here are a list of error codes and there meanings for Hotpoint washing machines

    These error codes can some times have a E in front of the number and not a F as shown here, but the meaning of the code is still the same



    # F11 - This means there is No hot fill.The ambient temperature is probably below freezing perhaps due to the plumbing becoming frozen. Also verify that the taps are on or if the drain hoses are kinked.
