Cordless vacuum runs but brush roll does not spin; brush indicator flashes or E6 displayed

Safety first: Turn OFF the vacuum, remove the battery pack, and keep fingers away from the brush area.

• Check for obstructions: Flip the floor nozzle over and remove hair, string, and debris wrapped around the brush roll and end caps. Ensure the brush can rotate freely by hand.
• Inspect belt (if belt-driven model): Remove the bottom plate of the nozzle (usually held by Phillips screws). Check the Hamilton Beach brush drive belt for breaks, cracks, or stretching. Replace if loose or broken.
• Check brush motor (direct-drive models): With the cover removed, inspect the small brush motor and wiring for burn marks or loose connectors. Reseat any loose plugs.
• Reassemble and test: Reinstall the belt and nozzle cover, insert the battery, and test on a hard floor. If the brush still does not spin and the error persists, the brush motor or control board is likely faulty.
• Advanced repair: Replacing the brush motor or wiring harness requires disassembly of the nozzle and soldering in some models. Seek professional service if you are not experienced with appliance repair.
