Sd - 肯摩尔 洗衣机

中文

含义

Sd（Suds / Suds Detected）表示洗衣机检测到桶内泡沫过多，超出系统安全处理能力。肯摩尔洗衣机通过电机负载电流变化和/或水位传感器波动判断是否出现”泡沫锁”（Suds Lock）现象——大量泡沫包裹衣物导致阻尼异常增加，电机负载降低而水位传感器持续感应到水压（泡沫柱）。一旦检测到泡沫过量，控制板显示 Sd 代码并自动进入”消泡程序”：暂停搅动，增加静置时间，部分机型会少量注水稀释泡沫，待泡沫自然消退后再恢复正常洗涤节奏。

常见原因

1. 使用了超出推荐量的高效（HE）洗涤剂，或使用了普通非 HE 洗涤剂——非 HE 洗涤剂产生泡沫量是 HE 洗涤剂的 3-5 倍。
2. 洗涤剂投放过量，尤其是用户凭感觉倒入而非按照刻度指示，常见于大瓶装无刻度盖的洗涤剂包装。
3. 所洗衣物本身含有大量残留洗涤剂或柔顺剂，来自前次洗涤时漂洗不彻底，累积残留物遇水再次起泡。
4. 选择了”快洗”或”节水”模式，该模式使用较少的水量，导致同等洗涤剂用量下泡沫浓度成倍增加。
5. 衣物量过少（如只洗两三件薄 T 恤），桶内水量虽然正常但摩擦搅打作用弱，泡沫无法被衣物物理压破。
6. 使用了已经变质或结块的洗衣液/洗衣粉，其中的表面活性剂分解产物会生成异常稳定的泡沫。

自助排查

1. 如果机器正在显示 Sd 且处于暂停状态，不要手动干预——洗衣机正在执行自动消泡程序，通常需要 5-15 分钟，请耐心等待 Sd 代码自行消失。
2. 以后洗涤时严格控制洗涤剂用量：使用 HE 洗涤剂的刻度线指引，普通脏污衣物用最小推荐量，重度脏污才按最大量投放。液体洗涤剂不要超过瓶盖第一条刻线。
3. 确认使用的洗涤剂包装上是否标有”HE”或”高效”标志。肯摩尔洗衣机必须使用 HE 洗涤剂；如果没有，停止使用并购买 HE 专用产品。
4. 前开式机型可在观察窗看到泡沫情况：如果正常洗涤 5 分钟后桶内仍然布满浓密泡沫且看不到水，说明洗涤剂严重过量，今后将用量减少至原来的三分之一。
5. 洗涤吸水性强的新毛巾、新棉质衣物时，这些物品会吸附并带出大量洗涤剂，泡沫容易过度。建议洗涤此类物品时额外增加一次漂洗程序。
6. 每月至少运行一次”桶清洁”或”高温自洁”程序（不放衣物），使用洗衣机专用桶清洁剂或白醋清除内桶和管路中的残留洗涤剂堆积。
7. 如果严格按照 HE 洗涤剂推荐量使用且已运行桶清洁程序后 Sd 仍频繁出现，可能为水位传感器导气管内存在泡沫残液影响检测精度，联系肯摩尔售后清理或更换传感器管路。

Meaning

Sd (Suds / Suds Detected) indicates that the washer has detected excessive suds in the drum beyond the system’s safe handling capacity. Kenmore washers detect “suds lock” — a condition where excessive foam envelops the laundry causing abnormally increased damping, reduced motor load, while the water level sensor continues to sense water pressure (from the suds column) — through motor load current changes and/or water level sensor fluctuations. Once excessive suds are detected, the control board displays the Sd code and automatically initiates a “suds reduction cycle”: pausing agitation, adding extra standing time, and on some models, adding a small amount of water to dilute the suds, then resuming normal wash rhythm after the suds naturally subside.

Common Causes

1. Using more than the recommended amount of high-efficiency (HE) detergent, or using regular non-HE detergent — non-HE detergent produces 3–5 times more suds than HE detergent.
2. Excessive detergent dispensing, especially when pouring by feel rather than following the graduated markings — common with large detergent bottles that lack a measuring cap with graduations.
3. The laundry itself contains a large amount of residual detergent or fabric softener from a previous wash with insufficient rinsing, and the accumulated residue foams again upon contact with water.
4. Selecting the “Quick Wash” or “Water Saver” mode, which uses less water, causing suds concentration to increase several-fold at the same detergent dosage.
5. The laundry load is too small (e.g., washing only two or three thin T-shirts) — while the water volume is normal, the friction and beating action is weak and the suds cannot be physically broken down by the laundry items.
6. Using expired or clumped liquid/powder detergent where surfactant decomposition products generate abnormally persistent suds.

Self-Check Steps

1. If the machine is displaying Sd and is in a paused state, do not intervene manually — the washer is running its automatic suds reduction cycle, which typically takes 5–15 minutes. Wait patiently for the Sd code to clear on its own.
2. Strictly control detergent dosage going forward: follow the HE detergent graduated marking guidelines. Use the minimum recommended amount for normally soiled laundry and only use the maximum for heavily soiled items. For liquid detergent, do not exceed the first graduation line on the cap.
3. Check whether the detergent packaging carries the “HE” or “High Efficiency” logo. Kenmore washers must use HE detergent; if using non-HE, stop immediately and purchase HE-specific product.
4. Front-loader models allow viewing suds through the observation window: if the drum is still filled with dense suds with no visible water 5 minutes into a normal wash, the detergent dosage is severely excessive. Reduce future usage to one-third of the current amount.
5. When washing new towels or new cotton items with high absorbency, these items adsorb and release large amounts of detergent, making excessive suds likely. It is recommended to add an extra rinse cycle when washing such items.
6. Run a “Tub Clean” or “Sanitize” cycle (empty, no laundry) at least once a month, using a washer-specific tub cleaner or white vinegar to clear detergent residue buildup from the inner tub and plumbing.
7. If Sd still appears frequently after strictly following the HE detergent recommended dosage and running a tub clean cycle, there may be suds residue trapped in the water level sensor air hose affecting detection accuracy. Contact Kenmore after-sales service to clean or replace the sensor tubing.
