  • Cleaner detection malfunction

Possible Causes

  • Faulty thermistor or OWI sensor (high)

  3. Restore power and check if the error code reappears.

Technician Only Inspect and repair/replace sensor wiring and components

  1. Disconnect power to the dishwasher.
  2. Access the thermistor and OWI sensor and inspect wiring harness to control board for damage.
