含义
nD 表示洗衣机无法正常排水或脱水。此代码与 4E/5E 类似但更为严重——洗衣机在执行排水程序后仍检测到桶内有大量存水，或排水正常完成后内筒无法启动高速脱水旋转。故障可能位于排水系统、门锁安全开关或驱动电机。
常见原因
- 排水泵过滤器严重堵塞，排水泵过热保护停机，导致排水失败。
- 排水管路完全堵塞或弯折压扁，水流完全无法通过。
- 排水泵电机烧毁或损坏，供电正常但电机不运转。
- 排水完成后，机门锁安全开关故障，控制系统认为门未锁好而禁止高速脱水。
- 驱动电机或电机驱动板故障，排水正常但内筒无法旋转。
- 控制主板相关电路损坏，导致脱水信号无法正常输出。
自助排查
- 先尝试手动排水：打开前下方盖板，使用紧急排水管（部分型号有此功能）或缓慢旋出过滤器将桶内存水排出（准备水盆接水）。
- 彻底清理排水泵过滤器和泵腔，排除异物堵塞的可能。
- 检查排水管全程是否有严重弯折或压扁，确保排水管通畅。
- 重新关门并确认听到”咔嗒”锁门声，检查门封条是否有异物妨碍门锁。
- 拔下电源插头等待 3-5 分钟后重新插电开机，让洗衣机控制板复位后再尝试运行一个短程序。
- 若上述步骤均不能解决，大概率涉及排水泵、驱动电机或主控板硬件故障，请联系三星售后安排专业维修。

Meaning
nD indicates the washer is unable to drain or spin. This code is similar to 4E/5E but more severe — after the drain cycle, the washer still detects a significant amount of water remaining in the drum, or after successfully draining, the drum cannot initiate the high-speed spin. The fault may lie in the drain system, the door lock safety switch, or the drive motor.
Common Causes
- The drain pump filter is severely clogged, causing the drain pump to overheat and shut down for thermal protection, leading to drain failure.
- The drain line is completely blocked, kinked, or crushed, making it impossible for water to pass through.
- The drain pump motor is burnt out or damaged — power is supplied but the motor does not run.
- After draining, the door lock safety switch is faulty; the control system believes the door is not locked and prohibits high-speed spinning.
- The drive motor or motor drive board is faulty — draining works normally but the drum cannot rotate.
- The main control board has a damaged circuit in the spin control section, preventing the spin signal from being output.
Self-Check Steps
- First, attempt manual draining: open the lower front access panel, use the emergency drain hose (if equipped) or slowly unscrew the filter to drain remaining water from the drum (have a basin ready to catch water).
- Thoroughly clean the drain pump filter and pump cavity to rule out foreign object blockage.
- Inspect the entire drain hose for severe kinking or crushing; ensure the drain path is clear.
- Close the door firmly and listen for the “click” of the door lock engaging; check the door seal for any debris preventing proper locking.
- Unplug the power cord for 3-5 minutes, then plug it back in to reset the control board; try running a short cycle.
- If none of the above steps resolves the issue, the problem is likely a hardware failure in the drain pump, drive motor, or control board. Contact Samsung after-sales service for professional repair.
