Resolution
• Something is interfering with the rotor. Clear the rotor and reset.
• The operator has held down the START/STOP and implemented a
quick stop.
• Inspect the tubes for equal tube fill or improper placement. Once
corrected, rerun.
• If the balance error continues to happen, remove the tubes and
determine if the balance error still persists with an empty rotor.
• Inspect the rotor for improper installation.
• The unit has exceeded the normal operating temperature.
• Turn off the unit and allow to cool.
• The unit has experienced a non-normal tilt event.
• Make sure the unit is placed on a level surface. Once corrected,
rerun
• The lid has opened during the cycle. Check for proper operation of
