Most likely causes

  1. Failed vario (water-spray diverter) motor
  2. Faulty micro switch that reports motor position to the control board
  3. Loose or damaged wiring between the motor and control board
  4. Control board fault
Before you start — unplug the appliance and turn off the water supply. You'll be working near water and electrical parts, and drained water can be hot. If a step involves the pump, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Power resetPress POWER off, switch the breaker off for about 10 seconds, restore power, press POWER on, and start a new cycle.
2Inspect wiringWith power disconnected, check the vario motor's wiring and connector for loose or damaged contacts.
3Check the motor and switchVerify the vario motor and its feedback micro switch operate; a stuck motor or bad switch commonly causes nE.
4Call for serviceIf nE persists, have a technician test and replace the vario motor, switch, or control board.

Still showing nE?

If you’ve worked through every step and nE keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.
