Brushroll does not spin and F3 is displayed, sometimes accompanied by a flashing brush icon.

Safety first: Remove the battery and detach the wand and floor nozzle.

• Check wand connections: Inspect the electrical contacts at both ends of the wand for bent pins or dirt. Clean gently with a dry cloth.
• Inspect nozzle connector: Look at the plug/socket where the nozzle connects to the wand. Ensure it is not damaged or loose.
• Test handheld only: Some models allow direct connection of the nozzle to the handheld unit. If possible, connect directly and test. If the brush works, the wand wiring is faulty.
• Wiggle test: With the unit running (battery installed, be cautious), gently move the wand and nozzle connection. If the brush stops/starts, there is an intermittent wiring fault.
• Professional repair: Internal wiring or Hall sensor replacement in the nozzle requires disassembly and should be done by a technician or by replacing the entire nozzle.
