Risk level

High

Professional inspection is recommended.

Urgency

Immediate

Quick answer

LC or LE means the leak sensor has detected moisture even when no visible leak is present. Shut off power and water before inspection.

Safety first

Stop and check this first

  • Keep the water supply closed and the circuit breaker off when a leak is visible or moisture is near electrical parts.

Safe checks you can perform

  • Shut off water and power
  • Inspect accessible connections for moisture

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Locate and repair the leak or sensor condition

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Locate and repair the leak or sensor condition

    What they doUse a qualified installer or appliance technician to repair a leak or recurring LC or LE condition.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Shut off water and power

    No special tools

    Close the dishwasher water-supply valve and turn the dishwasher circuit breaker off before inspecting for moisture.

    The dishwasher may try to run its drain pump while the leakage code is active.

  2. Inspect accessible connections for moisture

    No special tools

    Look and feel for moisture at the accessible ends of the water-supply hose without opening electrical panels.

    Keep power off and do not resume use when a leak is found.

What it means

Samsung identifies LC and LE as leakage detection. Some Waterwall models can also show the code when the water reflector is blocked so that branch must remain model-specific.
