What does Err 3 mean on my Hamilton Beach SA-HB-40-DB-CERT?

If your Hamilton Beach Water Dispenser displays 'Err 3', it could be due to several reasons: The valve cam gear may have been manually rotated out of the “service” position, or there may be a faulty motor, motor drive, or switch. If the cam gear is out of the service position, the control will turn the motor on and drive the cam gear to the proper location. Replace the motor assembly or switch if they are faulty.
