Cordless Shark vacuum shows an error when switching to handheld mode from stick mode; the unit powers off unexpectedly.

Safety first: Remove the battery before inspecting the wand and handle connections.

• 1. Detach and reattach wand: Remove the wand from the handheld unit and floor nozzle. Reconnect firmly until you hear a click at both ends.
• 2. Inspect locking tabs: Check that the plastic locking tabs are not cracked or worn. A loose mechanical connection can cause intermittent electrical contact.
• 3. Clean electrical contacts: Wipe the metal contacts at both ends of the wand and on the handheld unit with a dry cloth.
• 4. Test in different configurations: Run the vacuum as a handheld only, then with the wand but no floor nozzle, then with the full assembly. Note when the error occurs to isolate the faulty section.
• 5. Replace wand or handle connector: If the error only appears when the wand is used, replace the wand. If the handle connector is loose or damaged, the main body may need replacement.
