Samsung Dishwasher Error Code 1E — What It Means & How to Fix It

What Does This Error Mean?

The 1E error means your Samsung dishwasher has a water level sensor problem. The sensor that measures how much water is inside can't read properly. The dishwasher stops mid-cycle because it doesn't know the water level.

Affected Models

DW80R5061US
DW80R9950UG
DW80N3030US
Most Samsung built-in dishwashers

Common Causes

The water level sensor (pressure switch) is faulty or stuck
The sensor wiring is loose or damaged
The air tube connected to the sensor is clogged or kinked
The main control board has a communication error with the sensor
Water or debris has gotten into the sensor housing

How to Fix It

Turn off the dishwasher and unplug it from the wall outlet.

Wait at least 5 minutes before plugging it back in.
Plug it back in and try running a new cycle.

A simple power reset clears temporary sensor glitches about 30% of the time.
Check under the dishwasher for any visible water leaks.

Water near the sensor housing can cause false readings.
Inspect the small rubber air tube that connects to the water level sensor.

If you can access it, make sure it's not kinked, cracked, or clogged with debris.
If the error returns after a reset, contact Samsung support or a technician.

The pressure switch or its wiring likely needs professional diagnosis.

When to Call a Professional

This is a critical error that usually requires a technician. The water level sensor is an internal part that's not easy to reach. Expect repair costs of $150–$300 including parts and labor. Do not run the dishwasher repeatedly with this error.

Frequently Asked Questions

Is the 1E error dangerous on a Samsung dishwasher?

It's not a fire hazard, but don't ignore it. The dishwasher can't properly control water levels. This could lead to overfilling or running dry. Get it fixed before running more cycles.

Can I fix the 1E error myself?

A power reset is worth trying first. Beyond that, this error usually needs a technician. The water level sensor is buried inside the machine. It's not a typical DIY repair.

How much does it cost to fix a Samsung dishwasher 1E error?

If a power reset doesn't fix it, expect $150–$300 for a professional repair. The sensor itself costs $30–$80. Most of the cost is labor to access and replace it.
