What Does LC Error Mean on Samsung DW80R7 Series?

Error LC on Samsung DW80R7 Series: LC. Follow the troubleshooting steps below to diagnose and fix this dishwasher issue. LC indicates a water leakage detection issue in your Samsung DW80R7 dishwasher. This error occurs when the leakage sensor detects voltage below 3V for 3 seconds, triggering safety shutdown. While some users can check visible leaks and connections, most cases require professional diagnosis due to the sensor’s location near critical components. Immediately unplug the dishwasher and inspect the base for standing water before proceeding. ## What Does LC Mean? The LC error code specifically means the dishwasher’s electronic control board has received abnormal voltage readings (≤3V for 3+ seconds) from the water leakage sensor. According to Samsung’s official service manual (DW80R7 series technical documentation, section 5.3.2), this triggers an automatic main relay cutoff to prevent electrical damage and flooding. The system attempts self-recovery by cycling the drain pump (20 seconds on/5 seconds off for 3 minutes) - if unsuccessful, LC persists. Approximately many LC cases originate from actual water leaks rather than sensor faults. ## Possible Causes 1. Physical water leak from the tub seal or door gasket (many cases) 2. Faulty leakage sensor located beneath the base pan (many cases) 3. Damaged wiring harness between the sensor and main control board (many cases) 4. Corroded sensor terminals due to prolonged moisture exposure (many cases)

5. Control board failure interpreting sensor signals (many cases) ## Troubleshooting Steps StepActionExpected Result
1Unplug dishwasher and remove the kickplateAccess to leakage sensor area
2Visually inspect base pan for standing waterPresence indicates active leak
3Check door gasket/tub seal integrityNo tears or deformation
4Examine sensor wiring (black/yellow wires)No cuts/disconnections
5Measure sensor voltage (requires multimeter)Should read 3.8-4.2V dry
6Reset by holding “Delay Start” + “Heated Dry” for 5 secondsError clears if transient issue If voltage readings remain below 3V after drying all components, the sensor requires replacement (Samsung part # DD82-01421A). ## When to Call a Technician Contact Samsung-certified repair if:
  • Water is actively leaking from structural components
  • Sensor voltage stays below 3V after thorough drying
  • Error recurs within 3 wash cycles post-reset
  • You lack electrical testing equipment
  • Repairs would void remaining warranty (average service cost: ) Technicians have specialized leak detection tools and can perform pressure tests unavailable to consumers. Approximately most professional LC repairs are completed within 90 minutes. ## Frequently Asked Questions ### Can I temporarily bypass the LC error to finish a cycle? Never bypass leakage protections - this risks severe water damage averaging $2,300 per insurance claim.

How much does a leakage sensor replacement cost? Parts cost plus labor; Samsung-authorizes 1.2 service hours for this repair.

Why does my DW80R7 show LC only on certain cycles? Heavy soil cycles use more water - likely indicates a slow leak at higher water pressures.

How often should leakage sensors be tested? Samsung recommends professional inspection every 24 months or after any major plumbing work. ### Is it safe to keep using my Samsung DW80R7 Series with error LC? If error LC does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the dishwasher with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error LC on a Samsung DW80R7 Series? Repair costs for error LC on the Samsung DW80R7 Series dishwasher depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a Samsung-authorized service provider for an accurate estimate based on your specific situation. ### What does error code LC mean on a Samsung dishwasher? Error code LC on Samsung dishwasher models indicates LC. When the water leakage sensor data is equal to or less t. This error is detected by the appliance’s internal diagnostic system and displayed to alert the user that attention is needed. Refer to the troubleshooting steps above for guidance on resolving this issue.
