Samsung Dishwasher Error Code LE — How to Fix (Leak error)

Why Your Samsung Dishwasher Shows Error LE

The Samsung Dishwasher error code LE is a common issue that can be caused by a variety of factors, including a faulty leak sensor, clogged drain pump, or damaged water supply lines. When the dishwasher detects water in the base, it will display the LE error code and stop the wash cycle to prevent further damage. In some cases, the error code may be triggered by a minor issue, such as a loose connection or a clogged filter, while in other cases, it may indicate a more serious problem that requires professional attention.

Common Causes

• Faulty leak sensor: The leak sensor is responsible for detecting water in the base of the dishwasher. If the sensor is faulty, it may trigger the LE error code even if there is no actual leak.
• Clogged drain pump: The drain pump is responsible for removing water from the dishwasher. If the pump is clogged or faulty, it can cause water to accumulate in the base, triggering the LE error code.
• Damaged water supply lines: If the water supply lines are damaged or kinked, it can cause water to leak into the base of the dishwasher, triggering the LE error code.
• Clogged filter: A clogged filter can prevent the dishwasher from draining properly, causing water to accumulate in the base and triggering the LE error code.

Things to Keep in Mind

For Samsung dishwasher models, it’s essential to refer to the user manual or manufacturer’s website for specific troubleshooting guides and repair instructions. If troubleshooting hasn’t resolved the issue after these steps, or if the issue persists after trying the above steps, you should contact a Samsung-authorized service provider for assistance. also, if your dishwasher is still under warranty, you can contact Samsung’s customer support at 1-800-SAMSUNG (1-800-726-7864) for further assistance. To prevent this error from occurring in the future, make sure to regularly check and maintain the dishwasher’s drain pump, filter, and water supply lines. When working with electrical appliances, always unplug the power cord before starting any repairs to avoid electrical shock or injury.

What Does Samsung Dishwasher Error Code LE Mean?

When your Samsung dishwasher shows the LE error, the unit is telling you that it has detected water in the base. The dishwasher’s leak sensor, located near the bottom of the cabinet, is triggered when it senses moisture that shouldn’t be there. This can happen even if the dishwasher has just finished a cycle and is standing still.

The problem matters because the sensor is a safety feature. If the sensor is tripped, the dishwasher will stop running to prevent water from flooding the floor or damaging the electrical components inside the cabinet. A persistent LE error can also mean the machine is not cleaning properly, leaving dishes dirty or even causing a small electrical short if water reaches the control board.

Common Causes of Error LE

• Cracked or damaged base seal – The rubber gasket that sits around the dishwasher’s lower edge can split or become worn, letting water seep into the base.
• Leaking door gasket – A torn or misaligned door seal can allow water to escape from the wash cycle and collect at the bottom.
• Clogged or kinked drain hose – If the drain hose is blocked or twisted, water may back up and pool inside the dishwasher.
• Faulty or dirty drain pump – A pump that isn’t removing water quickly enough can leave excess water behind.
• Improperly installed water inlet valve – A valve that leaks or is installed upside‑down can spray water onto the base.
• Water spillage from a previous cycle – Sometimes water can splash or drip from the spray arms and pool at the bottom if the dishwasher was left open or the door wasn’t closed properly.

How to Prevent Error LE

1. Check the door gasket every month – Look for cracks, gaps, or hardening. Replace the gasket (part number 210-12345) if it shows any damage.
2. Keep the drain hose clear – Inspect the hose for kinks or blockages once a year, especially before the winter season when debris can clog it.
3. Inspect the base seal – After each wash, wipe the base with a dry cloth. If you see any water left behind, the seal may need replacing.
4. Use the right detergent – Over‑foaming detergent can produce excess suds that spill over the rim and pool at the bottom.
5. Avoid overloading – A full dishwasher can cause spray arms to hit the walls and splash water onto the base. Load dishes loosely and leave space for water to circulate.

Frequently Asked Questions

Q: Can I just ignore the LE error and keep using the dishwasher?
A: No. Ignoring the error lets water stay in the base, which can cause mold, rust, or electrical problems. Turn the unit off and investigate the leak.

Q: How long does a leak sensor replacement take?
A: A qualified technician usually spends 30–45 minutes. DIY replacement can take about an hour if you follow the manufacturer’s instructions.

Q: Is the leak sensor the only part that can cause the LE error?
A: The sensor is the trigger, but the underlying issue can be a cracked base, damaged gasket, clogged drain, or a faulty pump. The sensor simply reports that water is present.

Q: Will the dishwasher work again after I fix the leak?
A: Yes, once the source of the water is removed and the sensor is reset, the dishwasher should resume normal operation.

Q: Do I need a special warranty to cover the parts?
A: Many Samsung appliances have a one‑year limited warranty that covers parts and labor for leaks caused by manufacturing defects. Check your warranty card or Samsung’s website for details.
