On my duet washer model GHW9150PW0. It was throwing the infamous F11 and door lock codes. After reading about online and doing some checking I decided to replace the CCU. Before I did that when we tried to get that one last load out of it it start throwing the F6 code with the intermittent F11. I replaced the CCU and did 4 loads with no problem, than the F6 start popping up again. I ran the machine in test mode all was well. Still throwing F6 when it is in working mode. Please help.

F11 is a communication error between main board and control unit..
check all plugs are firmly fitted (best to unplug and refit each one).
but usually it is the main Pcb..

The following list of codes indicates an electronics communication problem with the washer: - Duet HT washer - F01, F03, F06, F11, F23, F24, F27, F28, F29, F30, F31, F32, F35, F42, F61, F62, F63, F64, F65, F70, F71, and F99

If Pause/Cancel does not work:

1. Unplug washer or disconnect power for one minute.
2. Plug in washer or reconnect power.
3. Re-select the cycle and press Start.

NOTE: If the error remains on the display, call for service.

I would first replace the door latch/lock assembly, a number of users have and it fixed the F-11 error code completely. Its the cheapest part for this problem.

Hope helps.

To unlock the controls

Select and hold END OF CYCLE SIGNAL for 3 seconds until the
CONTROL LOCKED Status light turns off.

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.

I had same error code F11 and DL.....I sprayed the door lock (inside) with WD40......so far works OK

I had the same F11/DL problem. I tighten the two screws on the door latch and it's working great. for now

Just some part numbers to help if you need to order parts. For the GHW9200LWO Washer (Sanitary Cycle Model)- the part number for the CCU (Microcomputer or main computer) is 8181924. The part number for the Motor Control Unit (MCU) is 8182706. I did a search for the part numbers and found the CCU for $79.90 shipping included - the same part from Whirlpool was $190 plus with shipping included. I put the CCU on and my washer works perfectly again. Hope this helps someone since I had such a hard time finding out the correct part numbers. Whirlpool first sent me the MCU even though I specifically told them it was not that part but the CCU.

DL is a door lock error. This is usually an indication of a bad door latch. F11 is a serial communications error from the Central Control Unit CCU (which is your main computer). If the door latch is defective it could be generating the communications error code as well. A defective CCU can also give the same symptoms, though. Before replacing any parts, however, double check all you connections to make sure you don't have any loose wires. The least expensive of the two possible solutions would be to replace the door latch (about $50). The CCU can run between $150 and $250. Hope this leads you in the right direction.

I wanna thank all of you for your input. I had the "DL F-11" code also. My washer would run 12 minutes and then stop with the annoying beep and error codes. After learning that the "DL" was the door lock, I decided to order the part online for 50 bucks. After I placed the order I decided to take this $50 thing apart and give it a look-see. (Boys like to tear things apart!)
There is a solenoid inside that actuates the lock. My finding was that there was some hardened goo that seeped out of the solenoid. It didn't look good! I believe this to have caused an electrical imbalance that the computer didn't like, thus sending it into error mode.
Removal and installation was a snap. First I took the top off. Then to make room for my arm to get to the door-lock, I pushed the drum all the way back and held it in place by wedging a shoe in the front end. Then I pushed the drum to the side, opposite the door-lock, and wedged it with another shoe. This gave me plenty of room to reach the door-lock. Unplug the three connectors and remove the three screws from the front side of the door-lock. (Inside door at 2:00.)
Reverse order for the install!
Thanks again for your posts which led me in the right direction!

your inlet vaulve is sticking and allowing water to trickle through, only solution is to find if it is your hot or cold vaulve and replace it

It is saying there is a problem with your door Lock. when you close the door does it hold like it use too? try to open and close the door if it doesn't really close properly then you will just need a door latch. If the machine gives you an f11 code then its the main computer board that can also give your the door lock error. I would check the door first though.

Power off the wall, check to see if the connections to the door lock are tight. Or

Try some WD40 on the door mechanism of machine (not door) & open shut a few times; with the mains off the wall.

how do I find the answere to the F11 problem posted by jsrock516
