Samsung Dishwasher Error Code E31 – Water Level Sensor Error

If your Samsung dishwasher is flashing the dreaded E31 error code, don’t panic. This code signals a Water Level Sensor Error, which means the dishwasher is having trouble reading the water level accurately. The sensor might be faulty, blocked, or receiving incorrect data—stopping your appliance from running a full wash cycle. This guide will walk you through what this error means, how to check it yourself, and when it’s time to call in fast local help.

What Causes the E31 Error Code?

    The E31 code indicates a failure in the water level sensor. This part monitors how much water is in the dishwasher, ensuring it fills and drains correctly. If the sensor can’t detect water levels properly, it triggers this error and halts the cycle. Common causes include:

• A faulty or damaged water level sensor
• Clogged or kinked hoses connected to the sensor
• Wiring issues or poor electrical connections
• Faulty control board (in rare cases)

Can You Fix It Yourself?

Step 1: Power Cycle Your Dishwasher

Sometimes, resetting your appliance clears a temporary glitch. Turn off the power to your dishwasher for 5 minutes, then turn it back on.

Step 2: Check for Blockages

Inspect the water inlet hose and drain hose for clogs, debris, or kinks. Clear anything obstructing the flow.

Step 3: Inspect the Sensor

If you’re handy with tools, you can access the bottom panel and inspect the water level sensor for signs of damage, corrosion, or loose wires. However, this step may be better left to a technician unless you’re experienced with appliance repair.
