Possible Causes
Defective brush motor, Jammed brush roller, Broken drive belt (if belt-driven), Faulty brush motor driver on PCB
How to Fix / Troubleshooting
Safety first: Unplug the carpet cleaner and lay it on its side to access the brush head.
- Inspect brush roller: Remove the brush cover and check for hair, threads, or debris wrapped around the brush roller. Clean thoroughly.
- Check drive belt (if applicable): On belt-driven models, inspect the brush drive belt for breakage or slipping. Replace if worn or snapped.
- Test brush rotation: Rotate the brush by hand. It should turn freely. If seized, the brush bearings or end caps may need replacement.
- Check brush motor wiring: Open the brush head housing and inspect the brush motor connectors and wiring harness. Reseat any loose plugs.
- Measure motor resistance: With the motor disconnected, measure coil resistance. An open circuit indicates a failed motor that must be replaced.
