Hi, 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
Hi
An "F-11" error code on a Whirlpool Duet could cause your washer to become inoperable and stop in the middle of a load. The cause of the problem could be a number of things and may require new parts.
F11 can mean anything from motor to motor control board to ccu board to wiring harness connecting ccu to mcu to motor.
Identification
The "F-11" code could appear with the dash or without the dash on the LCD screen. Be aware that there is also an "F-H" code that could look similar to the "F-11" code. Listen for 11 beeps to go along with the error code's first appearance.
Effects
The error means that there is no communication between the "Motor Control Unit" and the "Central Control Unit." This means that any operation selected like "Pre-wash" or "Large Load" cannot be sent to the motor for the washer to operate.
Prevention/Solution
Open up the washer panel to check the wire connections between the two units. If any plugs are loose or unplugged, reconnect them. Check to make sure none of the wires are stripped, rusty or broken off. After you reconnect the wires, rerun the washer to see if the error appears again.
Warning
If you do not know or understand the inside components of your Whirlpool washer, leave the job to a professional. Contact the store where you purchased the washer or Whirlpool customer service directly.
Please get back to us if you have further query else please accept the suggestion.
