Its pretty comlicated requires dissasembly of the front of the washer. A good tech can do in 1 hour. You may want to pay for it rather than spending all day and possibly damaging something. Let me know if you need further assistance.

SOURCE: Kenmore Elite HE3t 11042922200 Front Loading. F02 drain Problem

We experienced the same thing. I was able to restart and locate the noise to the water pump. After disassembling the water pump found the impeller shaft sliding out. For some reason this shaft will not stay in place. Had to order a complete pump assembly as the electric motor is not available.

Kenmore elite E3t F11 error code


The "F11" fault code will display if the Motor Control Unit (MCU) has an internal failure; repeating under or over voltage, or over current conditions. If failure occurs during high speed spin the door unlocks after 3 minutes. The MCU (Motor Control Unit) is located beside the motor. See images below. Key #13 is the CCU and key #1 is the MCU.

The CCU (Central Control Unit) is located under the top along the side panel.

I recommend checking for loose wire connections at the MCU, CCU and motor. If you do not get any motor action at all, the MCU has likely failed.NOTE: Disconnect the power cord from the power source before removing the top and lower access panel. I recommend calling a service technician to diagnose and repair your washer.

Parts can be looked up and ordered at Sears PartsDirect

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:Sears Home Services .

Stops washing mid cycle flashes f11


Here is what the manufacture says about this error code followed by my comments.

Communication between the Central Control Unit (CCU) and the
Motor Control Unit (MCU) cannot be sent correctly.
What to do:
1. Unplug washer or disconnect power.
2. Check wire harness connections to the MCU, the motor, and
Central Control Unit (CCU).
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.

Phil's comments ---------->

This error usually indicates a failure of the circuit board that controls the motor. It is a repair I would suggest leaving to a professional as it can be tricky to diagnose the problem

What does a F12 error mean for a Kenmore Elite Frontload Washer


F12 isnt an easy code to diagnose. It means the mcu isnt communicating with the ccu.
The problem could be the door lock or either board. I would recommend calling a tech out.
It is similar to the F11 error - see the following.....


"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.
