1. The brush motor is not receiving power. Check that the power cord is properly plugged into an outlet and that the unit is turned on. Also, check the circuit breaker or fuse to ensure that the circuit is not tripped.
2. The drive belt is not properly seated. The drive belt is what connects the brush motor to the rotating brushes. If it comes off or becomes dislodged, the brushes will not rotate. Check the belt and make sure it is properly seated around the motor shaft and brush roller.
3. The brushes are worn out. If the brushes are worn out, they will not be able to generate enough friction to rotate. Replace the brushes if they are worn or damaged.
4. The brush motor is faulty. If the motor itself is faulty, it will not be able to power the brushes. Replace the motor if it is found to be faulty.
5. The water tank is not full or it is not properly connected to the carpet washer. If the water tank is not full, the brushes will not be able to get wet and will not be able to rotate. Ensure the water tank is filled to the maximum fill line.
6. The carpet washer is not properly assembled. Ensure that the carpet washer is properly assembled according to the manufacturer's instructions. Incorrect assembly can prevent the brushes from rotating.
7. There is a blockage in the brush head. A blockage in the brush head can prevent the brushes from rotating. Check the brush head and remove any blockages.
8. The carpet washer is not properly maintained. Regular cleaning and maintenance of the carpet washer are essential to ensure that it works properly. If the carpet washer is not properly maintained, it can cause issues such as the brushes not rotating.
