Samsung Dishwasher Error Code LC

What Does Error Code LC Mean on a Samsung Dishwasher?

Leak sensor activated — water detected at base of dishwasher.

The leak sensor in the base pan of the dishwasher has detected standing water, indicating a leak somewhere in the unit. The dishwasher will not run until the water is removed and the source of the leak is addressed. This is one of the most searched Samsung dishwasher errors.

What Causes Error Code LC?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

How to Fix Samsung Dishwasher Error Code LC

1. 1

   Remove water from the base pan

   Tilt the dishwasher slightly forward (remove the bottom rack first) to drain accumulated water from the base pan. Use towels to soak up remaining water.

   ⚠️ Turn off power at the breaker before tilting the unit.
2. 2

   Check detergent usage

   If you used too much detergent or the wrong type (non-HE), this creates excess foam that overflows into the base. Use only dishwasher-specific detergent, maximum 1 tablespoon per cycle.

3. 3

   Inspect the door gasket

   Run your hand along the entire door seal. Look for tears, hardened sections, or sections that have pulled away from the channel. A bad seal lets water out during the cycle.

4. 4

   Check all hose connections

   Inspect the water supply line, inlet valve connection, drain hose at the pump, and drain hose at the sink drain. Tighten any loose fittings. Replace cracked hoses.

5. 5

   Inspect the wash arms

   Remove the lower wash arm and check for cracks. A cracked arm sprays water at pressure against the base, triggering the sensor.
