Okay...the following link explains the "F11" error code along with troubleshooting advice.

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

First and foremost, UNPLUG the washer for at least 30 minutes BEFORE assuming you have a failed component. The 30 minute interval is recommended by the manufacturer to reset the computer. In many cases you could have a momentary glitch that just needs reset.

If resetting the computer does not work, the easiest way to determine a CCU failure is to eliminate all the other possible related problems, first. Check all the wiring, check the motor windings, and check the motor control unit. If everything else checks good, more than likely you have a failed CCU. Unfortunately, the CCU is non-serviceable and will require replacement. There is a tech sheet inside your washer behind the lower panel under the door that explains all the error codes and gives drawings showing the connector placement on the CCU. It is usually affixed to the back of the lower panel, or along one of the interior cabinet walls.

If you need to purchase a new one searspartdirect.com carries the part. Just type in your complete model number and a replacement CCU can be located under the "Control Panel Parts" heading as item number 15 (part #8182695R).

To replace the CCU, follow these steps:

1. Leave the washer UNPLUGGED & remove the top panel of the washer, by removing the three screws that hold the panel in place in the rear of the washer. With the screws removed, the panel will slide back, then lift off. The CCU is located in the middle, directly behind, and slightly above, the wash tub.
2. Swap all the connectors from the old CCU to the new one. The easiest way I have found to do this is to hold the new CCU in hand and swap the connectors one by one. Use care when handling the connector plugs and wires, they are fragile. There is enough enough slack to do this, but just barely.
3. Once the connectors are all moved to the new CCU, unmount the old unit and insert the new one. There are three tabbed clips that hold the CCU in place along the top. Just use a screwdriver and gently pry up to remove.
4. Insert new CCU (complete with connected wires) by snapping it in place in the mounting bracket.

NOTE: Another method of ensuring all the connectors are placed correctly, is to label each connector with tape or take a good clear photo using a digital camera.

I hope all this information helps you. Let me know if you require additonal assistance. Hopefully, you won't have to go the route of replacing parts.

Washer displays an F11 error code. I replaced the MCU but still the F11 code. Wire harness is good.


Hi.

It is probably the CCU (main control). Wiring harness, motor and drive train must be checked before replacing the CCU.

Here full troubleshooting for F11.

F11 is communication error between CCU (main control unit) and MCU (motor control unit - additional control module connected to motor and to CCU, located in a sealed box inside the washer).

This usually means that either CCU or MCU is defective. In some case the connectors or the wiring harness connecting the two modules is the problem.

The tech sheet says:

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

The wiring harness is tested using a multimeter to ensure that there is continuity between the MCU and CCU connectors. If a single wire is good it will read zero Ohms (closed) from contact to contact.
Motor is tested reading Ohms, it must be read about 6 Ohms on three different pairs of contacts.
Drive system in motor is checked observing if any of the parts are broken.
MCU and CCU are tested reading volts during operation and testing at component level. The testing must be done by a tech. Check CCU to see if there is any sign of failure (eg burnt spots).

Most of the time the problem is CCU. Trick to repair it include testing and eventually reheating the solder joint of the two on-board relays, cleaning connector contacts with circuit cleaner solution. This in case that the problem is CCU.

Disconnect the unit from power for five minutes as first test. This will reset CCU.

Try to turn on it stops and flashes f11


"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.

F11 appears


F11 appears to be a Serial Communication error (a digital signal problem between the motor, motor control unit, and the central control unit). Look for loose connectors on each of these items. The wiring harness may be at fault, or any of the above devices (sounds expensive). Good luck!

MY DUET AND ME


Ok, you have two issues here that will need to be corrected. check the details below.

F-11

Serial communication error

Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.

Potential Causes

• Check Wire Harness connections 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

Replace failed component.(Most common issue here is a failed wiring harness)


F-14

EEPROM error

The Central Control Unit (CCU) receives it’s data from an EEPROM on board the CCU. If there is an error reading this data it will cause this error.

Potential Causes

• A power glitch may cause this error. Try unplugging the Unit for two minutes to see if that fixes the error.
• Check CCU.

Replace failed component.(if the reset doesn't clear thsi issue, replace the CCU)

What do the F11 and F02 mean?\


hiyas here is the meaning for the codes
If the drain time exceeds 8 minutes, the water valves are turned off and F02 is flashed.

Press PAUSE/CANCEL twice to clear the display.

NOTE: After 4 minutes the “Sud” error will be displayed, then 4 minutes later the F02 error code will be displayed.

Potential Causes

• Check the drain hose and make sure it is not plugged or kinked
• Check the electrical connections at the pump and make sure the pump is running.
• Check the drain pump filter for foreign objects
• If the above does not correct the problem replace the pump

F11 Means
Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.

Potential Causes

• Check Wire Harness connections 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

Replace failed component.

I would suggest that you possibly call out an engineer
