What Does Error 3-2 Mean?

The KitchenAid dishwasher error code 3-2 indicates a malfunction in the drain pump, typically related to a shorted thermistor or Optical Water Indicator (OWI) sensor circuit. This error may cause unusual noises during operation and halt the dishwasher's functionality until resolved. The issue often relates to problems with water temperature sensing or optical water detection, and may require inspecting wiring and sensors for faults.

Common Symptoms:

  • Dishwasher displays error code 3-2 (sometimes shown as F3E2) on control panel
  • Dishwasher may stop operating and require error resolution before continuing operation
  • Possible issues detected with water temperature sensing or optical water detection

Possible Causes

  • Shorted thermistor/OWI sensor (medium)
  • Damaged or faulty wiring between sensor and control board (medium)

How to Fix Error 3-2
