Vacuum turns on but shuts off after a few seconds without any error code; battery LEDs may still show charge.

Safety first: Remove the battery pack before inspecting contacts or connectors.

• Step 1 – Check for movement: With the battery installed, gently move the battery and handle while the vacuum is running. If it shuts off when moved, a loose connection is likely.
• Step 2 – Clean and inspect contacts: Remove the battery and clean the contacts on both the battery and vacuum with a dry cloth. Look for burn marks or pitting.
• Step 3 – Test with another battery: If available, try a second Severin battery. If the issue disappears, the original battery contacts may be worn.
• Step 4 – Avoid strain on handle: Do not lift the vacuum by the battery or twist the handle excessively during use.
• Step 5 – Professional inspection: If the problem persists with multiple batteries, internal connectors or solder joints need to be checked and reworked by a technician.
