What E6 means on a Mabe dishwasher

The E6 error code on a Mabe dishwasher indicates a temperature sensor failure. The temperature sensor, also called a thermistor, is responsible for monitoring the water temperature inside the wash tub and reporting that data to the control board. The control board uses this information to regulate heating cycles, determine when water has reached the correct temperature for washing and sanitizing, and advance through the wash program properly. When the sensor sends a signal that falls outside the expected range, the control board logs E6 and may halt the cycle to prevent damage or unsafe operation.

The two primary failure modes covered by E6 are a short circuit and an open circuit (broken sensor). A short circuit causes the sensor to report an abnormally low resistance value, making the board interpret the water as extremely hot when it may not be. A broken or open sensor produces no continuity, causing the board to read no temperature signal at all. Either condition prevents the dishwasher from accurately managing the heating element and wash cycle timing.

Diagnosing E6 starts with a physical inspection of the temperature sensor and its wiring harness. Look for visible damage to the sensor body, corrosion on the connector terminals, or wiring that has melted or chafed against the heating element. If the wiring appears intact, the sensor itself should be tested with a multimeter for continuity and resistance. A faulty sensor will need to be replaced, and any damaged wiring in the harness must be repaired or replaced before the new sensor is installed.

Common causes of E6

  1. 01

    Failed temperature sensor (thermistor)

    Part replacement

    The thermistor itself has burned out, shorted internally, or broken open, causing it to send an invalid signal to the control board. Testing with a multimeter will show either no continuity or a resistance value far outside the normal range.

  2. 02

    Corroded or loose sensor connector

    Wiring / connection

    Moisture inside the dishwasher can corrode the electrical connector where the sensor plugs into the wiring harness, creating a poor or intermittent connection. Inspect the connector terminals for green or white corrosion deposits and check that the connector is seated firmly.

  3. 03

    Damaged wiring harness

    Part replacement

    The wires running from the temperature sensor to the control board can become chafed, pinched, or melted if routed near the heating element. A visual inspection along the full length of the harness will reveal any breaks or insulation damage.

  4. 04

    Water or detergent contamination on sensor

    Wiring / connection

    Heavy mineral buildup or detergent residue can coat the sensor body and affect its ability to read temperature accurately. Cleaning the sensor surface and surrounding area may resolve the issue if no physical damage is present.

  5. 05

    Faulty control board

    Part replacement

    If the sensor and wiring both test correctly, the control board itself may have a damaged input circuit that is misreading the sensor signal. This is the least common cause and should only be considered after all other components have been ruled out.

Frequently asked questions about E6

What does E6 mean on a Mabe dishwasher?
E6 on a Mabe dishwasher indicates a temperature sensor failure. The control board has detected either a short circuit or a broken open condition in the thermistor that monitors water temperature. Because the dishwasher cannot confirm proper water temperature, it stops the cycle and displays E6 to alert you to the problem.
Can I fix the E6 error on my Mabe dishwasher myself?
Some causes of E6, such as a loose connector or light corrosion on the sensor terminals, can be addressed by a confident DIYer with basic tools. However, replacing the temperature sensor or diagnosing wiring harness damage requires comfort working with electrical components inside the appliance. If you are unsure, a qualified appliance technician can diagnose and repair the issue safely.
Is it safe to keep using my dishwasher when E6 is showing?
It is not recommended to continue running the dishwasher while E6 is active. Without a working temperature sensor, the control board cannot properly regulate the heating element, which could result in water that is not hot enough to sanitize dishes or, in a short-circuit scenario, incorrect heating behavior. Stop using the appliance until the sensor issue is resolved.
Will resetting my Mabe dishwasher clear the E6 error?
A reset may temporarily clear the E6 code from the display, but if the temperature sensor or its wiring is actually faulty, the error will return as soon as the dishwasher attempts to monitor water temperature again. A reset is useful for confirming whether the fault is persistent, but it does not repair the underlying hardware problem.
How much does it cost to repair the E6 error on a Mabe dishwasher?
Repair costs depend on what component needs to be replaced. A replacement temperature sensor is generally an affordable part, and DIY replacement can keep costs low. If the repair requires a technician, expect to pay for both the part and a service call, with total costs typically ranging from around $80 to $250 depending on your location and whether additional wiring or control board work is needed.
