COMPONENT CHECKS:

1.FLOAT SWITCH:

Check out the float switch with an ohm meter. When the

float is up, the switch is closed. When the float is down,

the switch is open.

STICKING FLOAT SWITCH:

It is important to remember that the float switch is in the

water circuit and is susceptible to scale buildup. This can

cause the float to stick either up or down. If the float

switch is sticking, it should be cleaned thoroughly with ice

machine cleaner and checked for proper operation. If the

float switch is defective, it should be replaced however, a

dirty float switch is not considered a warranty item.

The symptoms of a sticking float are:

UP/CLOSED: 60 minute freeze cycle, larger cubes,

and pump cavitates prior to harvest.

After 2 consecutive maximum freeze cycles, the

unit will shut down on a 3 beep safety.

To reset this alarm, press the Alarm Reset but

ton on the board with power ON.

DOWN/OPEN: Unit shuts down on low water

safety and water runs continuously.

Heavy scale can be difficult to remove from the float. The

float is available as a replacement part as well as the float

pin. If the housing is defective, replace the complete float

switch assembly.
