含义
8-1 表示洗碗机的排水速度低于正常水平，但尚未达到完全排不出水的严重程度。肯摩尔洗碗机在排水阶段会监测排水泵的工作状态和排水时间。当排水泵正常运行但排水时间超过了程序预设的正常排水时长（例如正常排水需 60 秒，实际用了 90-120 秒）时，控制板即显示 8-1 提示代码。与 2-1（完全排水失败）不同，8-1 属于预警级别：洗碗机仍能完成排水，但排水效率明显下降。此代码通常不会被锁死，洗碗机可能仍可继续完成当前洗涤程序，但建议尽早排查以恢复正常性能并避免恶化成 2-1 故障。
常见原因
- 滤网内有较多的细小食物残渣和油脂，未完全堵死但增加了水流通过的阻力。
- 排水管内壁常年积累了油垢层，管径变窄，排水流量受限。
- 排水泵叶轮上缠绕了少量纤维、头发或标签纸碎片，降低了泵的工作效率。
- 排水管有一段被压在洗碗机底部或被橱柜挤压，形成了轻微的限流点。
- 厨余处理器内部积存的污垢或未充分粉碎的食物，在排水口附近形成局部阻力。
- 排水泵电机的启动电容容量衰减，电机转速下降导致排水流量不足。
- 排水管末端的防虹吸弯或止回阀部分堵塞，阻碍水流的顺畅排出。
自助排查
- 取出并彻底清洗粗滤网和细滤网（铜滤网/不锈钢滤网），注意用软刷清洁滤网细孔，确保滤网没有残留的油脂膜。
- 在滤网已移除的状态下，用手触摸泵腔入口和排水口周围区域，检查是否有残余的食物碎渣或异物，清理干净。
- 检查水槽下方排水管的全程走势，确保没有任何部位被橱柜侧板、洗碗机底座或其他物品压迫，所有拐弯应是平滑的圆弧而非死角。
- 从水槽排水口端暂时拔下排水管，放入桶中检查排水流量：排水水流应有明显的冲力且呈连续状，如果水流断断续续或无力，说明管路或泵存在阻力。
- 如果家中安装了厨余处理器，运行一次厨余处理器（打开冷水冲 30-60 秒）以清除处理器内的积渣，再尝试洗碗机排水。
- 考虑使用专门的洗碗机清洁剂（如 Finish 或 affresh 品牌）运行一次空转清洁程序，以溶解排水管路内壁的油脂沉积。
- 若以上措施均不能改善，则排水泵可能存在性能衰减（叶轮磨损或电机老化），建议联系肯摩尔售后进行泵性能检测和预防性更换。

Meaning
8-1 indicates that the dishwasher’s drain speed is below the normal level but has not yet reached the severity of a complete drain failure. Kenmore dishwashers monitor the drain pump’s operating status and drain duration during the drain phase. When the drain pump is running but the drain time exceeds the program’s preset normal drain duration (e.g., normal drain takes 60 seconds but the actual time is 90–120 seconds), the control board displays the 8-1 advisory code. Unlike 2-1 (complete drain failure), 8-1 is a warning level: the dishwasher can still complete draining, but the drain efficiency has noticeably decreased. This code is typically non-latching — the dishwasher may still finish the current wash cycle — but it is recommended to investigate and resolve the issue early to restore normal performance and prevent it from deteriorating into a 2-1 fault.
Common Causes
- The filters have accumulated a moderate amount of fine food particles and grease — not completely clogged but increasing flow resistance.
- The inner wall of the drain hose has built up a layer of grease deposits over the years, narrowing the effective pipe diameter and restricting drain flow.
- The drain pump impeller has a small amount of fibers, hair, or label paper fragments wrapped around it, reducing the pump’s efficiency.
- A section of the drain hose is being compressed under the dishwasher or pinched by the cabinet, creating a mild flow restriction point.
- The garbage disposal has accumulated sludge or insufficiently ground food waste, creating localized resistance near the drain connection.
- The drain pump motor’s start capacitor has lost capacity, causing the motor to run at reduced speed and deliver insufficient drain flow.
- The anti-siphon loop or check valve at the end of the drain hose is partially blocked, impeding smooth water discharge.
Self-Check Steps
- Remove and thoroughly clean the coarse filter and fine filter (copper mesh or stainless steel mesh). Use a soft brush to clean the fine mesh pores, ensuring no residual grease film remains on the filters.
- With the filters removed, feel around the pump chamber inlet and drain port area by hand to check for remaining food debris or foreign matter; clean everything thoroughly.
- Inspect the entire routing of the drain hose under the sink, making sure no section is compressed by cabinet side panels, the dishwasher base, or other objects. All bends should be smooth curves, not sharp kinks.
- Temporarily disconnect the drain hose from the sink drain connection and place it into a bucket to check the drain flow: the water stream should have visible force and be continuous. If the flow is intermittent or weak, there is resistance in the plumbing or the pump.
- If a garbage disposal is installed, run the disposal with cold water for 30–60 seconds to clear any built-up sludge inside, then try the dishwasher drain again.
- Consider running an empty cleaning cycle with a dedicated dishwasher cleaner (such as Finish or affresh brand) to dissolve grease deposits on the inner walls of the drain line.
- If none of the above measures improves the situation, the drain pump may have performance degradation (impeller wear or motor aging). Contact Kenmore after-sales service for a pump performance check and preventive replacement.
