Cordless vacuum shows error on LED panel or flashes five times; unit will not start or stops quickly

Safety first: Disconnect the charger from the mains before inspecting plugs or sockets.

Steps:

• Check mains outlet: Plug another device (e.g., lamp) into the same outlet to confirm it has power.
• Inspect charger and cable: Look for cuts, kinks, or burn marks on the Hoover charger lead. If the cable is damaged, stop using it and replace with an original Hoover charger.
• Check charger indicator: Connect the charger to the battery or vacuum. Confirm that the charger LED behaves as described in the user manual (usually red while charging, green when full). No light or flashing error indicates a charger or battery fault.
• Clean charging contacts: Wipe the metal contacts on the battery and/or vacuum charging port with a dry cloth. Remove any dust or oxidation.
• Try another charger or battery (if available): Test with a known-good Hoover charger or battery to isolate whether the fault is in the charger, battery, or vacuum body.

If E5 remains: The internal charging PCB or battery pack may be defective. These components are not user-serviceable; replacement of the charger or battery, or professional repair of the main PCB, is recommended.
