Blue light flashes when trigger is pulled and vacuum stops quickly; indicates low or no charge.

Safety: Use only the correct Dyson charger for your model.

• Charge fully: Place the vacuum on charge for the recommended time (often 3.5–4.5 hours) until the light shows solid or turns off.
• Check charger connection: Ensure the plug is fully inserted into the wall and the charging port or dock.
• Inspect for damage: Look for damage to the charger cable or plug. Replace if damaged.
• Test runtime: After full charge, run the vacuum. If it still stops quickly with blue flashing, the battery is likely worn and should be replaced.
