含义
E23 故障代码表示干衣机检测到排气风道受限，空气流通不畅。控制系统通过监测排气温度变化速率或风压开关信号判断气流是否受阻，当排气阻力超过设定阈值时触发此代码。通风不良会导致烘干时间大幅延长、能耗增加，并存在过热安全隐患。
常见原因
- 干衣机外部排气管道过长、弯头过多或管径过细，增加排气阻力。
- 排气管内部绒毛积聚严重，形成局部堵塞。
- 外墙排风口格栅或防虫网被绒毛、灰尘或异物堵塞。
- 排气管被挤压、弯折或塌陷，尤其在机器后方狭窄空间内。
- 风压开关故障或连接软管脱落/堵塞，导致误判排气状态。
自助排查
- 断开电源，将干衣机拉出，检查后方排气管是否有明显弯折、挤压或塌陷，理顺管道走向。
- 断开排气管与干衣机的连接，用手或吸尘器清理管道入口处的绒毛堆积。
- 检查外墙排风口格栅，清除表面覆盖的绒毛和杂物，确保格栅叶片可自由开合。
- 测量排气管总有效长度，建议不超过 8 米且弯头不超过 4 个；超出此范围需改造管道或加装辅助风机。
- 若排气管路通畅但代码仍出现，检查风压开关及其连接软管是否完好、连接牢固，必要时更换风压开关。

Meaning
Error code E23 signals that the dryer has detected restricted exhaust vent airflow. The control board evaluates airflow by monitoring exhaust temperature rise rate or a pressure switch signal; when back-pressure exceeds the calibrated threshold this code is triggered. Poor ventilation significantly extends drying times, increases energy consumption, and creates a potential overheating hazard.
Common Causes
- External exhaust duct too long, has too many bends, or is undersized, creating excessive airflow resistance.
- Heavy lint accumulation inside the exhaust duct causing partial blockage.
- Outdoor vent hood or screen clogged with lint, dust, or debris.
- Flexible exhaust duct crimped, kinked, or collapsed, especially in tight spaces behind the dryer.
- Air pressure switch faulty or its sensing hose disconnected/blocked, causing false exhaust restriction readings.
Self-Check Steps
- Disconnect power, pull the dryer away from the wall, and inspect the rear exhaust duct for kinks, crushing, or sharp bends — straighten the duct path as needed.
- Disconnect the duct from the dryer and clear any lint buildup at the connection point using your hand or a vacuum hose.
- Check the outdoor vent hood — remove lint and debris from the cover and verify the flaps open and close freely.
- Measure the total effective duct length: keep runs under 25 ft (8 m) with no more than 4 elbows; exceeding this requires duct re-routing or a booster fan.
- If the duct path is clear but the code persists, inspect the air pressure switch and its sensing hose for damage or loose connections, and replace the switch if defective.
