How do I fix a F11 code on Whirlpool duet washer

SOURCE: Whirlpool Duet Washer

F11 is a serial communications error. This is a symptom of an electronic control board starting to go bad. As defined by the technical information provided by Whirlpool, the error could also be caused by a loose or broken wire connector and/or the central control unit (CCU) (front panel). I would double check all your wire connections leading to the control board and CCU, first. Don't be surprised, however, if the problem persists and you eventually have to replace the electronic control board. To check, follow these steps: 1. Unplug washer. 2. Remove the three screws along the top of the washer in the rear that holds the top panel on. 3. Once the screws are removed the top should slide back then lift up. 4. The electronic control board is gray (or white) in color and located in the rear of the washer. It's impossible to miss. Double check all the connections ONE AT A TIME. 5. Double check the wire harness connections leading to the front panel as well. I hope this resolves your problem, but experience has proven that this is usually an Electronic Control Board failure. It could actually be a combination of the CCU as well. The part numbers are as follows: Electronic Control Board: 959503 Central Control Unit: 1025824 Both boards cost about $150 each. Let me know if this helps you.

The shaking and vibration of the washer makes sense.  I took off the top cover and just pushed on the circuit board connections and the washer instantly worked.  Some of the connections did feel loose and by simply making sure they were connected tightly worked.  Save yourself a service call and try this first.  The circuit board is easy to get to.  Just remove the three screws from the back and the top cover comes right off.  This is for both the f11 and f dl fault codes.

"F11" is a serial communications error between the Central Control Unit (CCU) and Motor Control Unit (MCU), or interconnecting wiring. In a nutshell, the CCU, (which is the main computer board for the washer) has more than likely failed. You can try disconnecting the connectors and plugging them back in on the CCU, but I haven't had much luck with that remedy. You will need to UNPLUG the washer & take the washer top off by removing the three screws in the back to gain access to it. Once removed, slide the top back and then lift up. The CCU is located directly behind the wash tub.

If you cannot get the fault to clear and wish to repair this yourself, you can find the part at repairclinic.com. Just type in your complete model number and look for item number 1176592. The part lists for about $157. Searspartsdirect.com also has the part for much more, but offers informative troubleshooting diagrams. The CCU can be found under the "Control Panel Parts" heading as item number 15 (part #8182695). If you wish to do some comparative pricing of your own, use the part number provided by the Sears website.

If the washer still carries a warranty, this would be covered. Doublecheck with the manufacturer on how long some parts are covered. Some of the electronics and mechanical parts are covered beyond the one-year limited warranty that generally comes with your appliance.

I know this may be discouraging news, but you can repair this yourself and avoid labor costs. It may seem expensive, but considering how much these washers cost (I know, because I own one), it may be worth the effort. I hope this helps you. Post back if you have further questions or need instructions.

I believe EVERY machine will have this F11 error eventually. Here is what fixed mine. Remove the top cover by removing the three 7mm screws on the back of the machine at the top. Slide the cover to the rear and lift off. The CCU board has 2 relays on it. They have white plastic covers. One is labeled K4 and I believe the other is K2. There are five legs on each relay soldering them to the circuit board. Remove the circuit board from the machine. It is the one you can see with the top off in the back of the machine. Unplug all the connectors. Unsolder the 2 relays...brand name Omron. With a jewelers screwdriver carefully remove the plastic cover on the K4 relay. Examine the contact points on the normally open contacts and I will guarantee they will look dull and burnt. They should be bright and shiny. You can burnish the contact points lightly and clean them with electrical contact cleaner. If you take off the cover of the 2nd relay you will see the contact points are nice and bright and shiny. Swap the 2 relays and resolder them on the circuit board. While you have the board out, take a pencil eraser and rub it on the contact points where all the connectors slide onto the board. Spray the electrical contact cleaner to wash any residue away. Carefully reinstall the circuit board and replace the top cover. Our machine has done dozens of loads since I did this with no more problems. I expect another failure at some point when the points deteriorate on the swapped relay. At that point I will try and find replacements for both relays. The K2 relay apparently has less voltage going thru the contacts and does not fail. If you feel real comfortable, you can check the "wiping" action of the points by manually operating the relay when you have it out. I adjusted mine to give a bit more wipe on both relays. I hope this helps...it worked for me!!

SOURCE: we keep getting a f11 and fdl code on our

"F11" is a Serial Communications error code. The following link explains:

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

The "Fdl" error code indicates a problem with the door latch, which may be the reason why the door will not unlock.

Now...before assuming you have any failed components, try unplugging the unit for AT LEAST 30 minutes in an attempt to reset the Central Control Unit (CCU). In many cases, these error codes are erroneous and can be reset in this manner. If the error code reappears following a CCU reset, then you have a legitimate problem.

Read through the link provided for pointers on how to troubleshoot the F11 error code. The two errors in conjunction with each other, usually indicates a failed CCU. The CCU controls the latching mechanism on the door. If the CCU is not communicating with the door latch correctly, the latch doesn't operate and you get the additional error code (Fdl).

You can trace the wires from the door latch to the CCU and unplug and reset them one at a time to make sure you have a good electrical connection as well. Do the same on the door latch end as well. To access, you simply need to remove the top panel of the washer. Remove the three screws in the back of the washer that holds the panel in place. With the screws removed, the panel will slide back and then lift off. The CCU is located directly behind the wash tub in the top center of the washer. NOTE: Make sure you UNPLUG the washer while doing this.

If you need to retrieve your clothes and the door remains locked, there is a manual release you can use to open the door. The following link explains:

I know this may be a lot to read through. Try the CCU reset first. This is the easiest option and doesn't require you to remove anything. Hopefully, this will correct your problem(s).

If you still have questions, please let me know. I hope you find this information helpful.
