Vacuum shows E9 and refuses to charge when placed on the charging dock or plugged into the charger.

Safety first: Unplug the charger from the wall before inspecting the dock or charging port.

• Step 1 – Check power outlet: Plug another device into the same outlet to confirm it has power.
• Step 2 – Inspect charger and dock: Look for frayed cables, bent pins, or burn marks on the Essentials charger and dock contacts. Do not use a damaged charger.
• Step 3 – Clean contacts: Use a dry cloth to wipe the metal contacts on the dock and the vacuum’s charging pads or port.
• Step 4 – Try direct charging: If your model supports both dock and direct plug-in charging, try the alternative method to isolate whether the dock is faulty.
• Step 5 – Test with another charger: If available, use a known-good Essentials charger of the same rating. If charging works, replace the original charger or dock.
• Step 6 – Internal fault: If E9 persists with a good charger and outlet, the internal charging circuit or battery management system may be defective and will require professional repair.

Warning: Only use chargers specified by Essentials for your model. Incorrect chargers can cause overheating or fire.
