LC - 三星 洗碗机

中文

含义

LC 表示洗碗机底部检测到漏水。三星洗碗机底部装有漏水检测浮子开关（也称为防溢传感器），位于底盘最低点。正常运行时浮子处于低位，当有水渗漏到机器底部积聚时，浮子随水位上升而浮起，触发开关闭合，主控板立即显示 LC 代码并停止所有程序运行以防止进一步漏水和电气危险。

常见原因

  1. 洗涤剂过量或使用了非洗碗机专用洗涤剂（如普通洗洁精），产生大量泡沫溢出内胆，泡沫消泡后积聚到底盘触发漏水传感器。
  2. 门封条老化、变形或夹有食物残渣，洗涤过程中水从门缝渗出。
  3. 内部水管接头松动或密封圈老化，在高压喷淋时发生渗漏。
  4. 洗碗机未调至水平，机身向一侧倾斜，正常洗涤时水从某一侧溢出溅到底盘。
  5. 排水管接口不严或排水泵密封失效，在排水阶段有少量水泄漏。
  6. 内胆底部有微小的裂缝或锈蚀穿孔（较罕见，多见于老旧机器）。

自助排查

  1. 打开洗碗机门，检查底部是否有明显积水。如有少量水，用干毛巾吸干，重新启动一个短程序观察是否再次漏水。
  2. 确认使用的是洗碗机专用洗涤剂（洗碗粉/洗碗块/洗碗液），切勿使用普通洗洁精；如之前误用，运行一次空洗（不放餐具和洗涤剂）充分冲洗内胆残留泡沫。
  3. 检查门封条整圈是否有破损、变形、发霉或卡有异物，用湿布清洁门封条并确保其与门框紧密贴合。
  4. 检查洗碗机四个底脚，调节至水平状态；可用水平尺放在门框上沿辅助判断。
  5. 检查进水管和排水管两端接头是否拧紧，用手拧紧松动的接头（切勿使用工具过度紧固）。
  6. 若以上步骤完成后重新开机仍显示 LC，说明内部管路或密封件有隐蔽漏点，请切断电源和水源，联系三星售后拆机检修。

English

Meaning

LC indicates that water leakage has been detected at the bottom of the dishwasher. Samsung dishwashers have a leak detection float switch (also called an anti-flood sensor) installed at the lowest point of the base pan. Under normal operation, the float stays down. When water leaks and accumulates at the bottom, the float rises with the water level and closes the switch. The main control board immediately displays the LC code and halts all program operations to prevent further leakage and electrical hazards.

Common Causes

  1. Excessive detergent or the use of non-dishwasher detergent (such as regular dish soap), generating large amounts of suds that overflow the tub; the suds dissolve and accumulate in the base pan, triggering the leak sensor.
  2. The door gasket is aged, deformed, or trapped with food debris, allowing water to seep out from the door seal during the wash cycle.
  3. Internal water hose connections are loose or sealing rings have aged, causing leaks during high-pressure spray cycles.
  4. The dishwasher is not leveled, tilting to one side and causing water to splash over and drip into the base pan during normal operation.
  5. The drain hose connection is not tight or the drain pump seal has failed, causing small water leaks during the drain phase.
  6. The bottom of the inner tub has a small crack or rust perforation (rare, typically in older units).

Self-Check Steps

  1. Open the dishwasher door and check for visible standing water at the bottom. If a small amount of water is present, soak it up with dry towels and run a short cycle to observe whether it leaks again.
  2. Confirm you are using dishwasher-specific detergent (powder, tablet, or liquid). Never use regular dish soap. If dish soap was mistakenly used, run an empty cycle (no dishes, no detergent) to thoroughly flush residual suds from the tub.
  3. Inspect the entire door gasket for tears, deformation, mold, or trapped debris. Clean the gasket with a damp cloth and ensure it seats tightly against the door frame.
  4. Check the four leveling feet and adjust until the dishwasher is level; a spirit level placed on the top edge of the door frame can help.
  5. Check that the connections at both ends of the inlet and drain hoses are tight. Hand-tighten any loose fittings (do not use tools to overtighten).
  6. If the LC code still appears after completing the above steps, there is likely a hidden leak point in the internal plumbing or seals. Disconnect power and water supply, then contact Samsung after-sales service for a disassembly inspection.
