SOURCE: Iget a f-11 trouble code on my kenmore elite he4t washer.
REplace your MCU. 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. Go onto kenmore.com and find your right washing machine and replace the part yourself. First try and take the wiring harness off and then reconnect it and see if the error code goes away if it doesnt then replace the part. Please Rate. Thank you
SOURCE: kenmore elite he4t won't start getting door lock
I have exp. this problem before. I know of 3 causes for it.
1. The door lock is faulty. You will need to call Sears in for this. This wasn't my prob., but I got a free door lock replacment, anyway.
2. The washer shook loose a control wire to the circuit board. This can be caused by excessive vibration. You need a special type of screwdriver to open the top by removing the 2 screws in the top corners on the back. Slide the top off, push all the wires in, JIC, then put the top back on. Easy fix. I solved not having this happen by using the high spin speed instead of the extra high speed spin.
3. The control board is faulty. Call in a service man, pay $a lot, he will order the boatd, wait 2 more weeks so he can get it, let him install it, pay $a lot, use only HE detergent, or else this will happen in about another year.

The F33 error code indicates a pump drive system error. If the pump ohms out correctly & the harness is secure I recommend replacing the CCU (central control unit).
Please see the following image provided for instructions.

Remember to disconnect power to the washer before attempting access.

Drive Motor Tachometer Error
The control is unable to properly detect motor speed and the machine will shut down. If a failure occurs during high-speed spin the door will be unlocked after 3 minutes.
Potential Causes:
* Check wire harness connections between the Drive Motor/Tachometer and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU)
* Check the Drive Motor
* Check the MCU
* Check the Wire Harness
begin troubleshooting right at the motor. Why start there? Because the motor is one of the prime suspects and it's easy to check. Remove the back panel and unwind the belt from the drum pulley. Now turn the motor pulley (sans belt) by hand. If it doesn't turn smoothly and easily, you have a bad motor.
If the motor pulley turns smoothly and easily by hand, next step is to run the motor with the belt still removed from the motor pulley. If the motor seems to run fine that way, put the belt back on and run it again. If the motor won't run under load (with the belt on), then that's another sign that the motor is bad.
Suppose the motor turns easily and freely by hand but won't run either with or without the belt. This is a more subtle condition because we're probably dealing with a bad MCU or flakey wire harness somewhere between the motor and MCU, or between the MCU and the CCU.
One trick that often works at this point is to remove and reinsert all wire connections at the board and motor. This tends to clean the small amount of corrosion that will build up on the connections. After you do this put the machine into a service cycle (see the instructions in the tech sheet found inside the unit or you can ). Part of the service cycle is running the motor at certain set speeds which checks the tach.
If you've removed/reinserted the wire harnesses and still no joy, then usually the problem is the MCU.
