⚠ Common mistakes to avoid

  • Confirm the part matches your exact model number before buying — Dyson reuses parts across lines.
  • Never wash a filter unless it's marked washable, and dry it fully (24h) before refitting.
  • Don't force the part — if it resists, check alignment before applying pressure.
  • Always disconnect power (or remove the battery) before any internal work.
