      Your Central Machinery Ultrasonic Jewelry Cleaner might not start due to a few reasons: there may be no power at the outlet, the cord might not be properly connected, or the automatic overheating safety shut-off feature may have tripped. Check the power at the outlet and ensure the cord is plugged in securely. If the unit overheated, allow a fifteen-minute cool-down period before trying to use it again.
