2. Bin Control Cleaning
Scale may build up on BC. Scale can cause the actuator paddle and magnet to stick. In
this case, BC should be cleaned.
CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews are
securely in place after the icemaker is serviced. Make sure that none have fallen
into the dispense unit/ice storage bin.
1) Turn off the power supply.
2) Remove the front panel, then move the control switch to the "OFF" position.
3) Clear any ice away from BC.
4) Carefully remove the BC cable from the cable ties in the evaporator case, then remove
the BC from the bin control bracket and move to the front of the icemaker for cleaning.
5) Remove the actuator paddle from the switch mount. See Fig. 1.
6) Wipe down BC with a mixture of 1 part of Hoshizaki "Scale Away" and 25 parts of warm
water. Rinse the parts thoroughly with clean water.
7) Reassemble BC and replace it in its correct position.
Note: If the magnet was removed for cleaning, be sure to replace it in its correct
position.
8) Replace the BC cable into the cable ties in the evaporator case, then move the control
switch to the "ICE" position.
9) Confirm CB wire harness connections are secure, then replace the control box cover in
its correct position.
10) Turn on the power supply to start the automatic icemaking process.
