Error code F3E1 (3-1)
Appliance Dishwasher
Quick answer

Kenmore F3E1 explained: what each sensor does and the order of checks from the manual.

Model compatibility

Kenmore reuses codes across series and model years, so F3E1 (3-1) may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Thermistor (water temperature sensor) or OWI (optical water indicator) sensor failure.

Sensors behind F3E1

  • Thermistor: measures water temperature.
  • OWI sensor: the Optical Water Indicator, which senses debris in the water.

Covered models: Kenmore HE, Kenmore Global HE and Kenmore MicroClean HE dishwashers.

Steps in order

  1. Unplug the dishwasher.
  2. Check the wiring from the electronic control board to the thermistor/OWI sensor.
  3. Repair or replace the wire harness if it is broken.
  4. If the wiring is fine, replace the thermistor/OWI sensor.

Related codes

  • F3E2: the same sensor reads as shorted.
  • F3E3: calibration or drain hose check valve trouble.
  • F2E2: a panel communication fault, not a sensor one.
