Samsung dishwasher LC: Moisture protection has activated

Documentation checkedBy ErrHiveUpdated October 28, 2026

THE SHORT ANSWER

Moisture protection has activated.

LC means the leakage sensor has detected moisture. The dishwasher may run its drain automatically and resist the normal off command.

First safe check

Turn off power at the breaker before inspecting accessible leak sources.

Applies to

Samsung dishwasher families covered by the cited US guidance. Match the full model number and exact display; this is not an exact-model compatibility claim.

Before you start

Let the interior cool before reaching inside. Watch for sharp debris. Leave electrical, heater and pump access to a qualified technician.

Use the checkboxes to keep track as you read. Stop at any warning or step that does not match your appliance.

Look for visible moisture
Check accessible supply connections and the floor. Close the water supply if a leak is found.
What to note
Active leakage is contained before further checks.
Review recent changes
Tell the installer about a new disposal connection; check for excess detergent and, on WaterWall models, an obstructed reflector.
What to note
The likely trigger is documented without bypassing the sensor.

THE DETAILS MATTER

Scope & troubleshooting notes

How to interpret this result

A dry floor does not disprove the warning: moisture may be inside a protected area. Do not tip the machine or disable the sensor just to make LC disappear.

YOUR NEXT DECISION

When to stop and get help

Keep a leaking machine out of use and arrange installation correction or service. Do not defeat moisture protection.

Record what you see

Keep the full model number, exact displayed code, and your observations together for the next conversation.

Use the right support

Contact the manufacturer or a qualified appliance technician when the guide calls for service.
