If beating on the top makes it work, then you need a Main control CCU. Not the interface board located behind the buttons, but the other one in the top panel. Do not attempt to dis-assemble relays.

F11 and FdL flashes during the wash cycle or at the end. The door locks and the clothes are held hostage


Hi

F11 is a motor control unit error which means that the motor control unit has repeating under or over voltage or over current conditions due to internal failure. You can check the wire harness connections between the motor and the MCU (motor control unit) and also between the central control unit & MCU. If the motor is working then replace the motor control unit. Hope this helps...please post back for further assistance.

I have an F11 code


Washer will suddenly stop with 1 minute left on cycle and shows the F11 error code...at times it may show the FdL code. The washer will then not finish no matter what I do. If I unplug the unit from the outlet that does not guarantee that when I plug it back in it will start up. Fifty percent of the time it still shows the F11 error. It can take hours to finally get the washer to cancel out so I can take the laundry out that has not been spun out.

The F11 error code indicates a serial communication problem between the central control board and the motor control board. This can be caused by:

  • A loose or failed wire harness connection between the central control board and the motor control board.
  • A bad wire harness connection between the motor control board and the drive motor.
  • A failed drive motor.
  • A defective motor control board.
  • A failure in the central control board.

The diagnosis of this failure usually requires a technician. If you are able to unplug the washer and safely access the central control board and motor control board, you can check for a loose wire harness connection.

When pushing start, washer beeps 3 times but won't start


Hi,

Is the machine showing a "code" like FdL or F11 in the window where the numbers count down? The machine won't start because it thinks there's a problem. FdL and F11 are often times the codes most displayed when the machine beeps and won't start. FdL means a door lock problem and F11 means a motor or motor control board problem. If it's flashing either one of those codes the problem is most often the CCU circuit board in the machine (inside, top, back, plastic case) The CCU circuit board has what's called cold solder joints causing bad communication between the CCU and the door lock and/or the motor or motor control board. The cure for this is to remove the case with the circuit board then remove the circuit board and resolder the points on the circuit board where the spade connectors and relays (5 of them) connect to the circuit board. If you're good with soldering techniques the job is easy. If not, take the board in the case to a good appliance repair shop (along with this response) and they should be able to help you out. Good luck.

Our whirlpool elite washer keeps F11 erroring and FDL locking the door.


Hi.

FDL is door lock. This is the first part to be tested, since it can be symptom of a wiring problem.

The door lock is tested by reading impedance on the door latch contacts.
If the door lock is OK, do the following troubleshooting for F11. The problem is usually CCU.

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.

The diagnosis of this failure usually requires a technician. If you are able to unplug the washer and safely access the central control board and motor control board, you can check for a loose wire harness connection. Beyond that, I recommend calling a service technician to diagnose and repair your washer. The location of the internal washer components and component access for the central control board and the motor control board are in the images below.

F11


these error codes are not specific FDL can mean door latch failure .it can also mean the ccu board has failed also F11 can mean mean anything from motor to motor control board to ccu board to wiring harness connecting ccu to mcu to motor. if you do not know how to diagnose with out error code you may end up buying wrong part. sometimes doorlatch is not problem central control board CCU is

Random electrical problems, sometimes it works beautifully, sometimes not!


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

FDL=
A Door Lock Error occurs if the door cannot be locked. It will try to lock
it six times before displaying the error code.

■ Door lock mechanism is broken or removed from door.
■ Door switch/lock unit failure.
1. Unplug washer or disconnect power.
2. Check door switch/lock unit.
3. Check the wire harness connections to the door
switch/lock unit and Central Control Unit (CCU).
