中文
含义
错误代码 i30 表示洗碗机底盘漏水检测传感器已触发。洗碗机底部集水盘中安装有浮子开关或电极式漏水传感器，当检测到积水时立即中断所有运行程序并强制排水，以防止水漫溢至地面造成更大损失。
此错误代码属于安全关键类故障。即使肉眼未发现明显漏水，也必须彻底排查来源后方可重新使用洗碗机。
常见原因
- 进水管路或接头松动 — 进水软管与进水阀、三通接头的连接处因振动或安装不到位而渗水。
- 门密封条老化或破损 — 橡胶密封条开裂、变形或嵌入食物残渣，运行时门缝漏水流入底盘。
- 排水泵或进水阀壳体破裂 — 塑料壳体因冻裂或老化出现细微裂纹，在相应工作阶段渗漏。
- 洗涤剂分配器或喷淋臂漏水 — 分配器盖关闭不严、或喷淋臂上盖卡扣损坏导致溅水。
- 浮子开关本身故障 — 浮子卡在上升位置或开关触点粘连，造成假性漏水报警。
自助排查
- 立即断开电源并关闭供水角阀，用毛巾或海绵吸干底盘积水，防止电气部件短路。
- 检查所有可见水管接头是否有水滴渗漏，紧固松动的卡箍和螺纹接头。
- 目视检查门密封条是否完好、是否有食物残渣附着，用湿布清洁密封条表面并检查是否平整贴合。
- 打开洗涤剂分配器盖，确认其关闭卡扣正常；检查上下喷淋臂是否安装到位、有无破损。
- 若清理干燥后重新注水仍触发 i30，浮子开关可能已损坏或内部仍有隐蔽漏点，必须联系专业维修人员检修。
English
Meaning
Error code i30 indicates that the leak detection sensor in the dishwasher base pan has been triggered. A float switch or conductance-based water sensor sits in the plastic tray beneath the unit; when moisture is detected, the control board immediately stops all operations and runs the drain pump to minimize water damage.
This is a safety-critical fault. The appliance must not be used until the leak source is identified and repaired, even if no standing water is visible at first glance.
Common Causes
- Loose water supply hose connections — vibration or incomplete tightening at the inlet valve or T-fitting causes slow dripping into the base pan.
- Worn or damaged door gasket — the rubber seal is cracked, deformed, or has debris embedded, allowing water to escape the door during a cycle.
- Cracked drain pump or inlet valve body — freeze damage or material fatigue produces hairline cracks that leak only when the respective component is pressurized.
- Detergent dispenser or spray arm leakage — the dispenser lid does not latch fully, or the upper spray arm retainer clip is broken, causing splashing.
- Faulty float switch — the float is stuck in the raised position, or the switch contacts are welded shut, producing a false leak alarm.
Self-Check Steps
- Immediately unplug the dishwasher and shut off the water supply valve. Remove standing water from the base pan with towels or a sponge to prevent electrical damage.
- Inspect all visible water line connections for drips — tighten loose hose clamps and threaded fittings as needed.
- Examine the door gasket for cracks, tears, or embedded food debris. Wipe the gasket with a damp cloth and verify it seats evenly against the door panel.
- Open the detergent dispenser and confirm the lid snaps shut securely. Check both spray arms for proper installation and visible cracks.
- If the error returns after drying and refilling, the float switch may be defective or a concealed leak remains — contact a qualified technician for full inspection.
