Vacuum will not charge, charger LED flashes or E5 appears on display when battery is docked

Safety first: Unplug the charger from the mains before inspecting the charger or battery contacts.

• 1. Inspect charger and cable: Check the Swan charger for damage, frayed cable, or a loose plug. Do not use if damaged.
• 2. Clean contacts: Wipe the metal contacts on the charger dock and battery pack with a dry cloth. Ensure there is no burnt or melted plastic around the terminals.
• 3. Cool the battery: If the battery feels warm or hot, let it cool for at least 30 minutes before attempting to charge again.
• 4. Try another outlet: Plug the charger into a different wall socket. Avoid extension leads or multi-way adaptors during testing.
• 5. Test with another charger or battery (if available): If you have a second compatible Swan battery or charger, cross-test to identify whether the fault lies with the charger or the battery pack.

If E5 persists and the battery never charges, replace the Swan cordless vacuum charger first. If a new charger does not resolve it, the lithium battery pack is likely faulty and should be replaced as a complete unit.
