Ice Production Check | Hoshizaki DCM-500BWH-OS, DCM-500BAH-OS

6)Refill /Low Water Safety – As ice is produced, the water level in the reservoir drops. As the water level drops, the upper and lower float switches open. First, the upper float switch opens. Nothing occurs at this time. When the lower float switch opens, refill begins. The water control relay de‑energizes, the 90 second low water safety timer begins, and the inlet water valve energizes. The compressor, fan motor, and gear motor continue to run. When the upper float switch closes, the water control relay energizes, the 90 second low water safety timer terminates, and the inlet water valve de-energizes.

If the upper float switch fails to close within 90 seconds after the inlet water valve energizes, a 150 second shutdown sequence begins. 90 seconds after the 90 second low water safety timer is complete, the compressor and fan motor de-energize, 60 seconds later the gear motor de-energizes. The inlet water valve continues until the upper float switch closes. Diagnosis – Check that the reservoir fills. If not, check the water supply line, clogged water filters, dirty or sticking float switches, inlet water valve screen, water control relay contacts, voltage to the inlet water valve, and inlet water valve solenoid or drain valve leaking.

7)Drain Cycle – "FLUSH" LED is on. 12 hour timer activates the flush cycle and a 150 second shutdown sequence begins. 90 seconds after the 12 hour timer activates, the compressor and fan motor de-energize, 60 seconds later the gear motor de‑energizes. The drain valve then energizes and remains energized for 20 minutes. Once the 20 minute drain timer is complete, the 12 hour drain cycle timer resets and the fill cycle begins.

8)Shutdown – The bin fills and activates the bin control. A 150 second shutdown sequence begins. After the bin control has been open for 90 seconds, the compressor and fan motor stop, the agitating motor energizes for 0.6 seconds, and 60 seconds later the gear motor stops. Diagnosis: Check that the bin control paddle is activated and that the bin control switch opens. If the compressor and gear motor fail to stop, check the bin control (proximity) switch and control board relays.

B.Ice Production Check

To check production, prepare a bucket or pan to catch the ice and a set of scales to weigh the ice. After the icemaker has operated for 10 to 20 minutes, catch the ice production for 10 minutes. Weigh the ice to establish the batch weight. Multiply the batch weight by 144 for the total production in 24 hours. When confirming production or diagnosing low production, see "III.E. Performance Data."
