Whirlpool suit washer shows a F11 code. What is that telling me?

SOURCE: Kenmore Elite 459724 - F11 code

Riostar, F11 is a serial communication error. Communication between the main board and the motor control board is not being sent correctly. This could be a bad main board, motor control board or motor itself. The testing can get pretty involved. Try putting the machine in a self test mode and see if the error clears. Press Cancell, then by pressing the drain spin button once on the left side then move to the spin speed button the the right. Press this button until no-spin lights. Press the prewash button 4 times. C00 should appear in the display. Let it run it's tests, there will be 8 of them and end up on C08. If this doesn't work, it's best you wait for the service tech. Catriver...post back.

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 have read many posts for this problem and I have my own solution. I interface computers to real world aplications and when I saw the control board for this washer I was appalled at what I saw. The tiny relays on that control board are rated for 10 or 16 amps. These are fine if you are only driving small devices but they cannot take the startup currents and back EMF of solenoids and motors. I have tried filing the contacts and resoldering edge connectors all to fail to solve the problem. So, I replaced 2 relays involved in the most critical operations. One was the small relay (K4) that activates the door lock/unlock solenoids. BUT instead of simply replacing the relay, I rewired the harness and added an industrial relay to do the heavy work of actuating the solenoids. I also replaced the main relay (K6). This relay is what the entire machine uses for all motors, solenoids and other relays depend on to operate. Here again, I diverted where the power goes to. The power that normally passes through K6 is now just used to operate an industrial rated relay.
I used original relays for the control board due to the fact that the electronics on that board were intended to only operate tiny relays. I simply diverted the power to drive larger relays. This was no easy task and it is not to be performed by anyone other than an expert in this field. I have a number of photographs and I am willing to share them with anyone who wishes to see what I did.
I would bet that very few of these control boards have actuall gone bad. Only the relay contacts have been slightly scorched to the point of intermittent reliability.

YA, I HAVE A PROBLEM SAME AS THE OTHERS. AND JUST LIKE THE MANUAL SAYS, YOU ARE SAYING TO CHECK EVERYTHING, BUT YOU WILL NOT TELL US HOW TO CHECK IT, WHAT IT IS SUPPOSE TO SOUND AND LOOK LIKE, WHAT IS NORMAL. SO WE CAN TELL WHAT IS WRONG WITH IT. I DON'T HAVE ALL THIS MONEY TO SPEND ON REPAIR MEN WHO DON'T KNOW WHAT THEY ARE DOING. SO WHAT SHOULD I DO. OH AND P.S. F-28 DOES SHOW UP ON THE WASHER SO IT REALLY IS A ERROR CODE.
