Cordless vacuum will not turn on at all, no lights or sounds

Safety first: Ensure the charger and battery are handled with dry hands and away from liquids.

• Step 1 – Confirm battery charge: Place the vacuum on the charger for at least 30 minutes. Check for any LED activity on the charger or vacuum.
• Step 2 – Try a different outlet and charger: Rule out a bad outlet or charger by testing with another known-good Dirt Devil charger if available.
• Step 3 – Check battery seating: Remove and reinstall the battery, ensuring it locks firmly into place.
• Step 4 – Inspect power button: Press the power button repeatedly. If it feels stuck, mushy, or does not click, the switch may be mechanically failed.
• Step 5 – Internal inspection (advanced): If comfortable, open the housing and check for broken wires, burnt components, or loose connectors between the battery and main board.
• Resolution: Replace the battery if it will not accept charge. If the battery is good but the unit remains dead, replace the power switch assembly or main control board.
