Kenmore Washing Machine F11 error code

The main control board (CCU) cannot communicate with the motor control board (MCU). Without that link the washer cannot run the motor, so it stops.

Also shown as: F11, F 11

Last updated: October 6, 2026

Quick answer: Kenmore washing machine error code F11: control boards can't communicate. The most common cause is loose wire harness between the CCU and the MCU, often shaken loose during high-speed spin. Try this first — power-reset the washer. If that does not clear it, level the washer.

What causes the F11 error?

  • Loose wire harness between the CCU and the MCU, often shaken loose during high-speed spin
  • Failed motor control unit (MCU)
  • Failed central control unit (CCU)
  • Faulty drive motor
  • Washer not level, causing heavy vibration that loosens connectors

How to fix Kenmore F11 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Power-reset the washer
    Unplug the washer or flip its breaker off for 10 to 20 minutes. Plug it back in and press Stop twice to clear the display. Start a short cycle to see if the code returns.
  2. Level the washer
    Check that all four feet sit firmly on the floor and the washer does not rock. Heavy vibration during final spin is a common reason the serial-link connectors work loose. Re-level and retest.
  3. Reseat the serial-link wiring
    Unplug the washer and remove the top panel. Find the three blue serial wires running between the CCU and the MCU and push each connector on firmly. Reassemble, restore power, and test a spin cycle.
    Safety warning: Unplug the washer before removing the top panel or touching any wiring.
  4. Watch when the code appears
    If F11 only appears during the fastest part of final spin, vibration-related loose wiring is the likely cause. If it appears immediately at power-on, a failed board is more likely and needs a technician.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • F11 returns after reseating the wiring and leveling the washer
  • Connectors look burnt or corroded
  • The code appears immediately at power-on, before any cycle starts
  • A board (CCU or MCU) needs testing or replacement

Frequently asked questions

What does F11 mean on a Kenmore washer?

It means the main control board and the motor control board have lost communication with each other. The most common cause is a loose wiring connector between the two boards.

Is F11 a motor problem?

Not usually. It is a communication problem between the two control boards. The motor itself is one of the less common causes.

Can I keep using the washer with F11?

No. The washer will not run a cycle while this code is active. Reset it, check the wiring, and call a technician if it comes back.
