What E6 means on a Kenmore dishwasher

The E6 error code on a Kenmore dishwasher indicates an Auto Sensor fault. The auto sensor, sometimes referred to as a turbidity or soil sensor, is responsible for detecting the level of food soil and particulate matter in the wash water. Based on its readings, the dishwasher automatically adjusts cycle duration, water temperature, and water usage to match the actual load conditions. When this sensor fails or produces readings outside of expected parameters, the control board logs the E6 fault.

A key detail about this fault is that the dishwasher remains fully operational even when E6 is present. All standard wash cycles continue to function; the machine simply loses its ability to automatically optimize water and energy consumption. The appliance defaults to fixed cycle parameters rather than dynamically adjusting based on soil levels. This means dishes will still get cleaned, but the efficiency benefits of the auto-sensing feature are no longer available.

The most direct resolution is replacement of the auto sensor itself. Because the machine continues to operate, this repair is driven by preference for energy and water savings rather than immediate necessity. Technicians should verify wiring connections to the sensor before condemning the component, as a loose or corroded connector can produce the same fault without the sensor itself being defective.

Common causes of E6

  1. 01

    Failed Auto Sensor

    Part replacement

    The auto sensor itself has malfunctioned and is no longer producing valid readings. This is the most likely cause and typically requires sensor replacement to resolve.

  2. 02

    Loose or Disconnected Wiring Connector

    Wiring / connection

    The wiring harness connector at the sensor may have worked loose or corroded, interrupting the signal to the control board. Inspect and reseat the connector before replacing the sensor.

  3. 03

    Sensor Contamination or Fouling

    Wiring / connection

    Grease, mineral deposits, or debris coating the sensor's optical or conductive surfaces can cause inaccurate readings and trigger the fault. Cleaning the sensor may restore function in some cases.

  4. 04

    Damaged Wiring to Sensor

    Part replacement

    Physical damage to the wiring between the sensor and the control board, such as chafing or a broken wire, can mimic a sensor failure. Continuity testing of the harness will identify this condition.

  5. 05

    Control Board Communication Fault

    Part replacement

    In less common cases, the control board may fail to correctly process the sensor's signal even when the sensor and wiring are intact. If sensor and wiring checks pass, the control board may need evaluation.

Frequently asked questions about E6

What does E6 mean on a Kenmore dishwasher?
E6 on a Kenmore dishwasher indicates an Auto Sensor fault. The auto sensor monitors wash water soil levels and adjusts cycle settings automatically to save water and energy. When this sensor fails, the dishwasher logs E6 but continues to operate normally using fixed cycle parameters.
Can I still use my Kenmore dishwasher when it shows E6?
Yes, the dishwasher remains fully functional with an E6 fault present. All standard wash cycles will continue to run and clean dishes normally. The only loss is the automatic adjustment feature that optimizes water and energy usage based on load conditions.
Will resetting my Kenmore dishwasher clear the E6 error?
A reset may temporarily clear the E6 code from the display, but the fault will return if the underlying sensor issue has not been resolved. Because the sensor hardware is faulty or has a wiring problem, the code will reappear once the dishwasher attempts to use the auto-sensing function again.
Is it safe to run my dishwasher with the E6 code showing?
Yes, it is safe to continue using the dishwasher while E6 is active. The fault relates only to the soil-sensing and cycle optimization function, not to any component that affects water containment, heating safety, or drainage. The appliance operates in a standard fixed-cycle mode in the absence of sensor data.
How much does it cost to fix the E6 error on a Kenmore dishwasher?
Repair costs vary depending on what is causing the fault. If the fix is simply reseating a loose connector or cleaning the sensor, there may be no parts cost at all. If the auto sensor itself needs replacement, parts and labor together typically range from around $80 to $200 depending on the specific model and local labor rates. Control board replacement, if needed, would be at the higher end of repair costs.
