What F9E3 means on a Kenmore dishwasher

The F9E3 error code on a Kenmore dishwasher indicates that the control board has detected the diverter disc is missing from the sump assembly. The diverter disc is a round rotating component located in the sump at the base of the dishwasher. Its function is to direct water flow between the different spray zones during a wash cycle, including the lower spray arm and the TurboZone assembly. When the control cannot confirm the disc is present or operating correctly, it stops the cycle and triggers this fault.

The most direct cause of F9E3 is that the diverter disc has physically dislodged or was never reinstalled after a previous repair or cleaning. The disc can sometimes come loose during aggressive cleaning of the sump area or when the lower spray arm, rear feed tube, or outlet cover are removed and reassembled incorrectly. In some cases, a worn or cracked disc may have broken apart and been washed out of position, leaving the sensor unable to detect it.

Diagnosing this code begins with removing the lower spray arm, TurboZone assembly, rear feed tube, and outlet cover to gain a clear view of the sump. The round diverter disc should be visible and properly seated in its housing. If the disc is present but the error persists, the issue may involve the diverter motor or position sensor rather than a missing disc. However, confirming physical presence of the disc is always the correct first step before investigating electrical or mechanical drive components.

Common causes of F9E3

  1. 01

    Diverter disc dislodged during cleaning

    Wiring / connection

    The disc can fall out of its seat when the sump area is cleaned or when internal components like the spray arm or feed tube are removed. Check the sump cavity and the bottom of the tub for the disc.

  2. 02

    Disc not reinstalled after previous repair

    Wiring / connection

    If the dishwasher was recently serviced or disassembled, the diverter disc may have been left out during reassembly. Remove the lower spray arm, TurboZone assembly, rear feed tube, and outlet cover to verify the disc is seated correctly.

  3. 03

    Broken or cracked diverter disc

    Part replacement

    A disc that has cracked or broken apart may have shifted out of position or fragmented, causing the control to register it as missing. Inspect the disc closely for any visible damage or missing pieces.

  4. 04

    Diverter disc position sensor fault

    Part replacement

    If the disc is physically present and properly seated but F9E3 still appears, the sensor that detects disc position may be faulty or have a wiring connection issue. This requires further electrical diagnosis of the diverter circuit.

  5. 05

    Diverter motor failure

    Part replacement

    A failed diverter motor may prevent the disc from rotating to a detectable position, causing the control to interpret this as a missing disc. This is less common but should be considered after ruling out physical disc issues.

Frequently asked questions about F9E3

What does F9E3 mean on a Kenmore dishwasher?
F9E3 means the control board has detected that the diverter disc in the sump is missing. The diverter disc is a round component that directs water flow to different spray zones inside the dishwasher. The appliance will not complete a wash cycle until this condition is resolved. The first step is to remove the lower spray arm, TurboZone assembly, rear feed tube, and outlet cover to check whether the disc is present and properly seated.
How do I fix the F9E3 error on my Kenmore dishwasher?
Start by removing the lower spray arm, TurboZone assembly, rear feed tube, and outlet cover to access the sump area. Locate the round diverter disc and confirm it is properly seated in its housing. If the disc is missing, search the tub interior and sump cavity for it and reinstall it. If the disc is broken or cannot be found, a replacement disc will need to be installed before the error will clear.
Is it safe to use my Kenmore dishwasher when F9E3 is showing?
It is not advisable to run the dishwasher while F9E3 is active. Without a properly functioning diverter disc, water cannot be directed correctly through the spray zones, which means dishes will not be cleaned properly. Running the machine in this condition may also put unnecessary strain on the pump and motor components.
How much does it cost to fix a Kenmore dishwasher showing F9E3?
If the diverter disc simply needs to be repositioned, there is no parts cost and the repair is a straightforward DIY fix. If the disc is broken and needs replacement, parts typically range from $15 to $50 depending on the specific model. If the diverter motor or position sensor has failed, professional repair costs including labor can range from $100 to $250 or more.
Will resetting my Kenmore dishwasher clear the F9E3 error code?
A reset may temporarily clear the error code from the display, but F9E3 will return as soon as the control attempts to detect the diverter disc during the next cycle. The underlying issue, whether a missing, displaced, or broken disc, must be physically corrected for the error to stay resolved. Always address the root cause before relying on a reset.
