Repair Guide

How to Fix Error nE

  1. 1

    Power cycle the appliance

    Unplug for 5 minutes and plug back in. A temporary glitch may have triggered the error.

  2. 2

    Listen for the fan

    After plugging back in, listen near the fan location. If you hear grinding, clicking, or nothing at all, the motor or blades have an issue.

  3. 3

    Check for debris or obstructions

    Check the vent fan area for food debris, mineral buildup, or obstructions. In dishwashers, the fan is usually near the vent at the top of the door or in the drying system.

    Always disconnect power before accessing internal fan components.
  4. 4

    Spin the fan by hand

    With the appliance unplugged, try rotating the fan blade. It should spin freely with slight resistance. If it's stiff or locked, the motor bearings are seized.

  5. 5

    Check wiring

    Disconnect and firmly reseat the fan motor connector at both the motor and the control board ends.

  6. 6

    Replace the fan motor

    If the motor is confirmed bad, order a replacement for your model. Most fan motors are held by 2-4 screws and a single wire connector.
