Samsung Dishwasher Error Code LE

The LE code on a Samsung dishwasher stands for a low water level error. It appears when the high level sensor is not detected after a drain and refill cycle, or when the low level sensor stays active for more than 30 seconds during washing. This tells the control board that the tub is not reaching or maintaining the correct water volume. The dishwasher stops the cycle to prevent components from running without adequate water.

No, you should not continue running the dishwasher while the LE code is active. The error indicates the tub is not reaching the correct water level, which means the wash pump could run without sufficient water and sustain damage. Stop using the appliance and diagnose the issue before running another cycle.

Repair costs depend on the faulty component. If only a connector needs reseating or cleaning, the fix may cost little to nothing beyond your time. A replacement water level sensor typically costs in the range of $20 to $60 for the part, while a new inlet valve may run $25 to $75. If a technician is needed, labor costs generally add $100 to $200 or more depending on your location and the complexity of the repair.

Start by checking the water level sensor connectors for loose or corroded connections and reseat them if needed. Next, confirm that the water supply line is fully open and not kinked, and inspect the inlet valve screen for mineral buildup. If the water supply and connections are fine, the water level sensor itself may need to be tested and replaced. In some cases, the wiring harness between the sensor and the control board may also need to be inspected for damage.

A reset may temporarily clear the LE code, but it will return if the underlying problem is not fixed. To reset, turn the dishwasher off, disconnect power for a few minutes, then restore power. If the root cause, such as a faulty sensor, bad connector, or restricted water supply, is still present, the code will reappear during the next fill cycle.
