Instructions

How to diagnose this issue safely

Useful tools
  • Bright flashlight
  • Known-working wall outlet
  • Clean dry lint-free cloth
Before you begin
  • Power the handheld off, disconnect its charger, and remove a detachable battery only when the exact owner guide describes that action.
  • Use only owner-access points and maintenance actions documented for the exact machine code.
  • Do not charge a swollen, cracked, leaking, wet, unusually hot, or impact-damaged battery.
  • Do not open the charger, battery cells, or charging electronics, splice its cable, or bridge charging contacts.
  1. Confirm the DC31 configuration

    DC31 (DC31) is a bagless handheld body with direct-fit cleaning tools. Cataloged variants include DC31, DC31 Motorhead. The verified owner-service profile identifies it as the Dyson DC31 retired handheld family. Match the machine code and serial label before ordering a filter, bin, direct-fit tool, battery where owner-replaceable, or charger; a retail family name can cover incompatible hardware.

  2. Identify the exact direct charger

    Confirm the outlet works, then inspect the external plug, adapter, cable, connector, wall cradle where fitted, and matching wall charger and handheld charging inlet for damage, liquid, debris, heat, or discoloration. Use only the direct charger specified for the exact machine code.

  3. Clean and reseat dry connections

    With the charger unplugged, remove dry debris from the connector and inlet. Legacy battery/charger platform for which Dyson has ended manufacturer parts and service. Reseat the battery pack specified for the exact machine code only if it is owner-removable, then reconnect the matching direct charger.

  4. Read the documented indicator

    Allow the machine and battery to reach normal room temperature. Record the exact light pattern, screen message, or app message and compare it with the exact owner guide; do not guess from another Dyson generation's indicator pattern.

  5. Replace only confirmed charging hardware

    If testing isolates the external charger or adapter, replace the complete sealed assembly listed for the exact machine. Do not splice a cable, open a mains adapter, substitute a similar connector, or treat a battery, dock, or charge-port failure as a direct-charger repair.
