Vacuum shows E10 or a ten-blink pattern and will not charge when placed on the wall mount or dock.

Safety first: Unplug the charger from the wall before inspecting it.

Steps to try:

• Test outlet: Plug a lamp or phone charger into the same outlet to confirm it has power.
• Inspect charger LED: Plug the Eureka charger into the wall without the battery. The charger LED should light (steady or standby). If it stays off, the charger is likely defective.
• Check dock contacts: If using a wall-mounted dock, inspect the metal contacts for dust or oxidation. Clean gently with a dry cloth.
• Direct charge (if supported): Remove the battery and connect it directly to the charger, bypassing the dock. If it charges this way, the dock is faulty.
• Replace charger: If the charger LED never lights and the cord shows signs of damage (kinks, cuts), replace the Eureka OEM charger with the correct voltage and amperage rating.
