Cordless vacuum shows E6 and will not charge on the dock

Safety first: Unplug the charger from the wall before inspecting contacts. Do not short the contacts with metal tools.

• Step 1 – Verify power outlet: Plug another device into the same outlet to confirm it has power.
• Step 2 – Inspect charger and dock: Check the Philips charger for damage, frayed cable, or a loose plug. Ensure the dock is firmly mounted and not cracked.
• Step 3 – Clean charging contacts: On both the dock and the vacuum, gently clean the metal contacts with a dry cloth. Remove any oxidation or dust.
• Step 4 – Check alignment: Place the vacuum carefully on the dock, ensuring it sits fully and the contacts engage. Look for the charging indicator; if it does not light, gently wiggle the unit to see if contact is intermittent.
• Step 5 – Test with another charger: If possible, test with a known‑good Philips charger of the same voltage and connector type.
• Step 6 – If E6 remains: The internal charge circuit or battery pack may be open. Replacement of the battery pack or main PCB is required; this is typically a professional repair.
