Brush roll does not spin, but suction is normal and no error code is shown.

Safety first: Remove the battery and detach the motorized floor nozzle before working on it.

• Step 1 – Check brush roll for jams: Remove the brush roll and clear any hair or debris. Ensure it spins freely by hand.
• Step 2 – Inspect drive mechanism: If your Severin nozzle uses a belt, check for a broken or slipped belt. Replace with the correct Severin belt if damaged.
• Step 3 – Verify power to nozzle: Reattach the nozzle and start the vacuum. Gently wiggle the connector between the nozzle and tube. If the brush starts/stops, the connector or cable is faulty.
• Step 4 – Test with another nozzle (if available): If another motorized nozzle works, the original nozzle's internal motor or gears are defective.
• Step 5 – Replace nozzle assembly: Internal gears and motors are usually not serviceable separately. Replace the complete motorized floor nozzle.
