Manufacturer Narrative

The device was received for evaluation.There was a relationship found between the returned device and the reported incident.Product failed functional testing with motor stall error and overheating.Cause of overheating and errors is a corroded motor/gearbox.The motor/gearbox assembly was removed from the housing and the gearbox was removed from the motor.The gearbox was found to be jammed.The motor passed functional testing.The complaint was confirmed and the root cause has been determined to be corrosion of the gearbox assembly.A motor stall condition will result in increased current draw from the control unit which will heat the motor and hand piece housing.Factors which can contribute to gearbox corrosion include cleaning and sterilization methods and the chemicals involved.A review of the device history records showed there were no indications to suggest that the product did not meet manufacturing specification or would not be able to perform as intended.
