E. Float Switch Check and Cleaning
1. Float Switch Check
1) Remove the front panel and move the power switch to the "OFF" position. Move the
control switch to the "DRAIN" position.
) Move the power switch to the "ON" position.
3) Allow the water to drain from the reservoir, then move the power switch to the "OFF"
position and the control switch to the "ICE" position.
4) Remove the molex plug from the control box and check continuity across the oat
switch wires. Black (BK) to red (R) for the upper oat and black (BK) to dark blue (DBU)
for the lower oat. See Fig. 9. With the water reservoir empty, the oat switches are
open. If open, continue to step 5. If closed, follow the steps in "IV.E.. Float Switch
Cleaning." After cleaning the oat switches, check them again. Replace if necessary.
5) Replace the molex plug on the control box.
6) Move the power switch to the "ON" position and let the water reservoir ll.
7) Once the reservoir is full and the gear motor starts, move the power switch to the "OFF"
position.
8) Remove the molex plug from the control box and check continuity across the oat
switch wires. Black (BK) to red (R) for the upper oat and black (BK) to blue (DBU) for
the lower oat. They should be closed. Clean or replace if necessary.
2. Float Switch Cleaning
Depending on local water conditions, scale may build up on the oat switch. Scale on the
switch can cause the oats to stick. In this case, the oat switch should be cleaned and
checked.
1) Turn off the power supply.
) Remove the oat switch assembly from the reservoir cover. See Fig. 10.
3) Wipe down the oat switch assembly with a mixture of 1 part recommended cleaner
Hoshizaki "Scale Away" or "LIME-A-WAY" (Economics Laboratory, Inc.) and 5 parts
warm water. Rinse the assembly thoroughly with clean water.
4) While not necessary, the oats can be removed from the shaft during cleaning. If you
remove them, note that the blue oat is on top. The oats must be installed with the
magnets inside them towards the top of the switch. Installing the oats upside down will
affect the timing of the oat switch operation. See Fig. 9.
5) Rinse the oat switch assembly thoroughly with clean water and replace in its original
position.
