The Hoshizaki P00816-01 Float Switch is a water-level sensing component used in compatible self-contained crescent cuber ice machines. It detects changes in water level and sends a signal to the control system to support proper operation of the water circuit during the ice-making cycle. This switch is suitable for service when an existing float switch becomes worn, damaged, or fails to respond correctly to changing water levels. It can be used in restaurants, hotels, bars, cafeterias, and other foodservice facilities with commercial ice machines. Proper water-level sensing supports consistent ice machine operation and routine equipment maintenance.
