Kenmore Dishwasher Error Code nE — Water Level Sensor (Float Switch) Error
What this means
The nE error code on Kenmore dishwashers indicates the water level sensing system is not functioning correctly. The float switch assembly monitors the water level in the tub — when the water reaches the correct level, the float rises and triggers the switch to stop filling. If this system malfunctions, the dishwasher may underfill, overfill, or fail to start.
Alternate codes: NE
Step-by-step fix
4 stepsCheck the float assembly for obstructions
Open the dishwasher and remove the lower rack. Locate the float assembly — a small dome or cylinder at the bottom front of the tub. Lift it up and down several times. It should move freely without sticking. Remove any debris, food particles, or utensils that may have fallen around it.
Small items like bottle caps or food labels can wedge under the float and prevent it from rising — check carefully.
Clean the float assembly
Some float assemblies can be removed by twisting or pulling up. Remove it and clean the float, the stem, and the housing area. Mineral deposits from hard water can cause the float to stick.
Soak the float in white vinegar for 15 minutes to dissolve mineral buildup.
Test the float switch
Unplug the dishwasher. Remove the lower kick plate and locate the float switch underneath — it sits directly below the float assembly. Disconnect the wires and test with a multimeter. The switch should toggle between continuity and open circuit as you manually move the float up and down.
If the switch doesn't toggle cleanly or readings are erratic, replace it — float switches are inexpensive.
Replace the float switch if needed
Remove the mounting clip or screw holding the float switch. Disconnect the wires (note their positions), remove the old switch, and install the new one. Reconnect the wires and reinstall the kick plate.
Some models combine the float and switch into a single assembly — check your model number to order the correct part.
When to call a professional
If the float switch tests fine but the error persists, the main control board may not be receiving the signal correctly. A technician can test the board's input circuits and wiring continuity.
