Whirlpool Dishwasher Error Code F6 E5 — Turbidity Sensor Error
What this means
The F6 E5 error code on newer Whirlpool dishwashers indicates the turbidity sensor has failed. This optical sensor measures how dirty the wash water is and adjusts the cycle length and number of rinses accordingly. When it fails, the dishwasher cannot optimize cycles and may run excessively long or not clean effectively. Found on Whirlpool models with adaptive wash features.
Alternate codes: F6E5
Step-by-step fix
3 stepsClean the turbidity sensor
The turbidity sensor is located in the sump area at the bottom of the dishwasher tub. Remove the filter assembly. Locate the small optical sensor (usually a clear plastic window). Clean it thoroughly with a soft cloth and warm water to remove any film or debris.
Hard water film on the sensor window is the most common cause of false turbidity readings.
Check the sensor wiring
Access the sensor connector underneath the dishwasher. Ensure the connector is firmly seated and there are no damaged or corroded wires.
Water leaks from the sump area can corrode the sensor connector over time.
Replace the turbidity sensor
If cleaning does not resolve the error, replace the turbidity sensor. Remove the old sensor from its mounting position in the sump, disconnect the wire, install the new sensor, and reconnect.
The sensor may be part of the sump assembly on some models, requiring a larger replacement.
When to call a professional
If the sensor replacement does not clear the code, the control board's sensor input circuit may be damaged.
