Cordless vacuum stops and LED flashes three times repeatedly, often when using turbo or high power mode

Safety first: Turn OFF the vacuum and remove the battery. Allow the unit to cool for at least 30 minutes before further use.

• Step 1 – Empty dirt cup: Remove and empty the dirt container. Tap it gently over a trash can to dislodge compacted dust from the cyclone shroud.
• Step 2 – Clean filters: Remove the pre-motor filter (usually a foam or pleated cartridge inside the dirt cup lid) and the exhaust/HEPA filter (typically at the rear of the unit). Tap both filters gently to remove loose dust. If your Dirt Devil manual allows, rinse foam filters with lukewarm water only and let them dry completely for 24 hours before reinstalling.
• Step 3 – Check for blockages: Inspect the wand, flexible hose, and nozzle neck for clogs. Use a broom handle or similar blunt object to push out obstructions; do not use sharp tools that could puncture the hose.
• Step 4 – Inspect motor vents: Ensure the cooling vents around the main body are not blocked by dust or fabric. Wipe with a dry cloth.
• Step 5 – Test again: Once filters are fully dry and reinstalled, reattach the battery and test on normal power first. If E3 recurs quickly, the motor may be failing and overheating internally.
• When to stop: Persistent E3 after cleaning indicates a failing suction motor. Replacement of the motor housing assembly is recommended by a technician.
