If this procedure does not result in normal operation, contact the manufacturer for warranty service. Include the serial number on the bottom of the machine. If your unit has to be returned for replacement, you have the option of returning the unit or you can just return the motor itself (a much smaller package). The motor is revealed by unscrewing the three tiny screws around the skirt, about 2.5 inches up from the bottom of the sprouter. Contact Tribest toll-free at 888-254-7336, or 562-623-7150. Or via email at service@Tribest.com and follow their instructions.
