E03 低

E03 - 戴森 吸尘器

中文

含义

机器检测到气流阻力增大，指示前后过滤器需要清洁或更换。此为定期维护提醒，非硬件故障。

常见原因

  1. 前置过滤器（可水洗部分）累积过多灰尘，微孔堵塞
  2. 后置HEPA过滤器达到使用寿命，过滤效率下降
  3. 过滤器未完全晾干即装回使用，纤维结块阻碍气流
  4. 清洁高频使用（每日使用）后未按月维护过滤器
  5. 使用非戴森官方过滤器，过滤材料密度和透气性不匹配

自助排查

  1. 取出前置过滤器，在冷水下冲洗，同时用手指轻轻搓洗滤布表面直至水清
  2. 将前置过滤器充分晾干至少24小时，确保完全干透后再装回
  3. 检查后置HEPA过滤器状态，建议每6个月更换一次
  4. 清洁后若E03仍点亮，尝试轻敲过滤器去除深层积尘
  5. 确认使用的是戴森原装或认证兼容过滤器

English

Meaning

The machine detects increased airflow resistance, indicating that the pre-filter or post-filter requires cleaning or replacement. This is a routine maintenance reminder, not a hardware fault.

Common Causes

  1. Pre-filter (washable layer) loaded with fine dust, clogging the micropores
  2. Post-HEPA filter nearing end of service life, reduced filtration efficiency
  3. Filter reinstalled while still damp, causing fibers to mat and restrict airflow
  4. Heavy daily use without monthly filter maintenance
  5. Non-genuine replacement filter with incorrect material density and breathability

Self-Check Steps

  1. Remove the pre-filter and rinse under cold water, gently rubbing the fabric surface until the water runs clear
  2. Allow the pre-filter to dry completely in air for at least 24 hours before reinstalling
  3. Inspect the rear HEPA filter; replace every 6 months or sooner if visibly discolored
  4. If E03 remains after cleaning, gently tap the filter to dislodge trapped deep dust
  5. Confirm the filter is genuine Dyson or a certified compatible replacement
