Cordless vacuum shows E6 and will not charge when placed on the charger or dock.

Safety first: Unplug the charger from the mains before inspecting contacts. Do not open the charger casing; there are live components inside.

Check the charger:

• Verify mains outlet: Plug another device into the same socket to confirm it has power.
• Inspect charger LED: When you plug in the charger alone, note whether its indicator light behaves normally (refer to your Salter manual). No light may indicate a failed charger.

Inspect contacts:

• Examine the metal charging contacts on the dock and on the battery pack. Clean gently with a dry cloth or a cotton bud with a small amount of isopropyl alcohol. Ensure they are not bent or recessed.
• Ensure the vacuum or battery is correctly seated on the dock so that all contacts align.

Test with another charger: If possible, test with a known-good compatible Salter charger. If charging works, replace the original charger or dock.

If E6 remains with a known-good charger and clean contacts, the internal charge PCB in the battery or vacuum body is likely faulty. Replace the battery pack first; if the fault persists, the internal charge board or main PCB will require professional replacement.
