How to Fix Samsung Dishwasher Leak Sensor

If you own a Samsung dishwasher, you might occasionally encounter issues with its leak sensor. The leak sensor plays a crucial role in detecting water leaks and preventing potential damage. In this article, we will guide you through the steps to fix a Samsung dishwasher leak sensor, ensuring it continues to function optimally.

Before we delve into the troubleshooting steps, let’s understand the role of the leak sensor in a Samsung dishwasher. The leak sensor is a safety feature designed to detect leaks and abnormal levels of moisture within the dishwasher. It monitors the bottom of the unit and triggers an alarm or shuts off the dishwasher if it detects water leakage. This mechanism protects your kitchen from potential water damage and ensures the dishwasher operates safely. In the case of a dishwasher leaking into basement, the leak sensor becomes even more crucial as it can help prevent water from reaching the basement and causing further damage.

Identifying the signs of a leak sensor problem is crucial for timely intervention. Here are some common indicators that suggest your Samsung dishwasher might have a leak sensor issue:

  1. Constant Alarm: The dishwasher alarm keeps going off even when there are no visible signs of leakage.
  2. Water Accumulation: You notice water pooling at the bottom of the dishwasher after a cycle.
  3. Error Codes: The control panel displays error codes related to the leak sensor, such as “LE” or “LEAK.”
  4. Interrupted Cycles: The dishwasher stops running mid-cycle, accompanied by error messages related to water leakage.

Troubleshooting Steps for a Samsung Dishwasher Leak Sensor

To resolve a leak sensor problem in your Samsung dishwasher, follow these step-by-step troubleshooting procedures:

Step 1: Inspecting the Leak Sensor

Begin by examining the leak sensor for any visible signs of damage, such as corrosion or debris accumulation. Carefully inspect the wires and connections, ensuring they are secure and undamaged.

Step 2: Cleaning the Leak Sensor

Clean the leak sensor using a soft cloth or sponge dampened with warm water. Gently wipe away any dirt, grime, or residue that might be obstructing its functionality. Avoid using abrasive cleaners or harsh chemicals, as they can damage the sensor.

Step 3: Checking the Drain Hose

Inspect the dishwasher’s drain hose for any kinks, clogs, or damage. A blocked or damaged drain hose can cause water to back up and trigger false leak sensor alarms. Straighten any kinks and remove any obstructions to ensure proper water flow.

Step 4: Examining the Door Gasket

The door gasket forms a seal between the dishwasher door and the tub, preventing water from leaking out. Inspect the gasket for any signs of wear, cracks, or tears. If you notice any damage, replace the door gasket to ensure a proper seal.

Step 5: Verifying the Water Supply Line

Check the water supply line that connects to your dishwasher. Ensure it is securely connected and free from any leaks or damage. A loose or damaged water supply line can trigger false alarms from the leak sensor.

Step 6: Resetting the Leak Sensor

Resetting the dishwasher’s electronics can help resolve minor issues. Locate the circuit breaker or unplug the dishwasher from the power source for a few minutes. Afterward, reconnect the power and check if the leak sensor issue persists.

Step 7: Seeking Professional Help

If you have followed the troubleshooting steps and the leak sensor problem persists, it is advisable to seek professional assistance. Contact Samsung customer support or schedule a service appointment with a certified technician to diagnose and repair the issue accurately.

Preventive Measures for Samsung Dishwasher Leak Sensor Issues

Taking proactive measures can help prevent leak sensor issues in your Samsung dishwasher. Here are some preventive measures you can implement:

  1. Regular Maintenance: Clean the dishwasher regularly, including the filter, spray arms, and interior, to prevent debris accumulation that can affect the leak sensor’s performance.
  2. Proper Loading: Avoid overloading the dishwasher, as it can cause excessive water splashing and increase the chances of leaks.
  3. Check for Damaged Items: Inspect dishes, utensils, and glassware for any chips or cracks before loading them into the dishwasher. Broken items can damage the dishwasher and trigger leak sensor alarms.
  4. Quality Detergent: Use high-quality dishwasher detergent that is suitable for your dishwasher model. Low-quality or inappropriate detergents can cause excessive sudsing, leading to leaks and sensor issues.
  5. Regular Inspections: Periodically inspect the dishwasher for any signs of leaks, damage, or worn-out components. Timely detection can prevent further issues and costly repairs.


A malfunctioning leak sensor in your Samsung dishwasher can be frustrating, but you can address the issue effectively with the right troubleshooting steps. By inspecting the leak sensor, cleaning it regularly, and ensuring proper maintenance, you can keep your dishwasher running smoothly and prevent potential water damage. If all else fails, do not hesitate to contact Samsung customer support or a professional technician for assistance.
