Floor nozzle brush does not spin, display shows F1, suction still works.

Safety first: Turn OFF the vacuum, remove the battery, and detach the floor nozzle from the wand.

• Remove the brushroll: Open the brushroll cover (usually via latches or a coin slot). Lift out the brushroll.
• Clear obstructions: Cut away hair and threads with scissors, taking care not to cut bristles. Clean both end caps and the brush chamber.
• Check rotation: Spin the brushroll by hand. It should rotate freely without grinding. If it feels stiff or rough, the bearings may be worn.
• Inspect the drive system: On some Electrolux models, a belt or direct-drive gear connects the motor to the brushroll. Check for broken belts or stripped gears.
• Reassemble and test: Refit the brushroll and cover, reinstall the battery, and test. If F1 persists and the brush still does not spin, the brushroll motor or nozzle PCB may need replacement.
