Depending on local water conditions, scale may build up on the float switch. Scale on the 
switch can cause the float to stick. In this case, the float switch should be cleaned. 

1) Turn off the power supply.
2) Remove the front panel, then move the control switch to the "OFF" position.
3) Remove the insulation panel, then remove the drain plug located on the lower front part 

of the ice chute. See Fig. 3. Allow the water tank to drain.

4) Replace the drain plug in its correct position. Be careful not to cross thread it.
5) Disconnect the vent tube and the flush tube from the top of the float switch, then remove 

the float switch assembly from the mounting bracket and remove the rubber boot from 
the bottom of the float switch assembly. See Fig. 4.

6) Remove the retainer rod from the bottom of the float switch assembly, then remove the 

float. Be careful not to bend the retainer rod excessively when removing it.

7) Wipe down the float switch assembly's housing, shaft, float, and retainer rod with a 

mixture of 1 part Hoshizaki "Scale Away" and 25 parts warm water. Clean the inside of
the rubber boot and hose with cleaning solution. Rinse the parts thoroughly with clean 
water.

8) Reassemble the float switch assembly and replace it and the rubber boot in their correct 

positions. Reconnect the vent tube and the flush tube.

9) Move the control switch to the "ICE" position.

10) Replace the insulation panel and front panel in their correct positions.
11) Turn on the power supply to start the automatic icemaking process.
