2. Float Switch Cleaning
Depending on local water conditions, scale may build up on F/S. Scale on the switch can
cause the float to stick. In this case, F/S should be cleaned.
1) Remove the front panel. Move the control switch to the "OFF" position, then unplug the
icemaker from the mains socket.
2) Remove the base cover, then disconnect one end of the pump tubing to drain the water
tank. See Fig. 3. After the water tank has drained, reconnect the pump tubing.
3) Disconnect the vent tube and the flush tube from the top of F/S, then remove F/S
assembly and remove the rubber boot from the bottom of F/S assembly. See Fig. 4.
4) Remove the retainer rod from the bottom of F/S housing, then remove the float. Be
careful not to bend the retainer rod excessively when removing it.
5) Wipe down F/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.
6) Reassemble F/S assembly and replace it and the rubber boot in their correct positions.
Reconnect the vent tube and the flush tube.
7) Replace the base cover in its correct position.
8) Plug the icemaker back into the mains socket, then move the control switch to the "ICE"
position. Replace the front panel in its correct position.
