Jenn-Air Dishwasher F8-E2 Error: Turbidity Sensor Fault
What Does Jenn-Air Dishwasher Error Code F8-E2 Mean? The F8-E2 error code on Jenn-Air dishwashers means the soil sensor (turbidity sensor) that measures water cleanliness is not functioning correctly. This sensor tells the dishwasher when dishes are clean enough to end the wash phase. Common Causes Dirty or coated turbidity sensor: Grease or mineral film […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. The dishwasher will still complete cycles — it just cannot optimize wash time. Safe to use until repair is scheduled.
Can I reset the code?
Yes. Cleaning the sensor and power cycling the dishwasher may clear this error permanently.
When to stop immediately?
Stop if you notice: Error returns after thorough sensor cleaning, Cycle times exceed double the normal duration.
Symptoms You May Notice
Wash cycle runs much longer than normal
Without sensor feedback, the dishwasher defaults to maximum wash time, extending cycles by 30-60 minutes.
Dishes come out still dirty or over-washed
The sensor cannot gauge soil level, so wash performance becomes inconsistent.
Possible Causes
Dirty or coated turbidity sensor
Grease or mineral film on the optical sensor window prevents accurate readings.
DIY PossibleFailed turbidity sensor
The sensor element itself has failed and needs replacement.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean the sensor area
Remove the lower spray arm and locate the turbidity sensor near the sump. Wipe the sensor window with a soft cloth and white vinegar.
Run an empty cycle with a dishwasher cleaner tablet first to dissolve grease buildup.
-
2
Run a diagnostic cycle
After cleaning, run a normal cycle to see if the error clears and cycle time returns to normal.
If the cycle still runs excessively long, the sensor likely needs replacement.
When to Call a Professional
Contact a qualified technician if:
- Sensor reads out-of-range values in diagnostic mode
- Sensor connector shows corrosion or damage
- Sump area shows signs of water intrusion around sensor
