INTRODUCTION

Safety first!

To avoid electrical shock, unplug dispenser from power source before servicing inside.

WARNING: When powered, the condenser cooling fan will turn on every 30 minutes to aid cooling the entire unit, even when not in the ICE or CHILL modes. KEEP HANDS AWAY FROM FAN!

Basic Maintenance

In order to maintain proper machine operation, the shaft seals and bushings need to be replaced as a Preventa- tive Maintenance measure. A reminder message will appear every 6 months. Worn/dirty shaft seals/bushings will have a direct effect on torque sensing and prevent complete freezing in “ICE” mode.

“UPPER” case vs “lower” case

Before beginning the process of troubleshooting, verify simple operating modes, ie; “CHILL” mode will not freeze the product, but “ICE” mode will. You should also observe the letter case size in either mode. UPPER case means the solenoid valve for that side is open, lower case, solenoid is closed.
