Question about Hoshizaki Commercial Freezer KM-500MAH
This is manitowoc 50kg ice cube machine , water pressure is normal but machine cycle time 1.25 min ,the machine normal cycle time only for 35 min what is a problem of the ice cube machine?
I suspect a defective liquid line or pump down seleonid coil. just make sure you hear the "click" when it starts up if not the selenoid coils could be defective. also verify that the condenser fan is running,because if not you are short-cycling on high head pressure. please contact if you need any additional info

Tips for a great answer:
My name is Peter. I am a retired field service refrigeration technician.
The normal setting for a freezer is -2 to +2 degrees F., and the normal setting for the fresh food section is +35 to +40 degrees F.
You only have one source of cooling and that is your freezer. With the settings that you have, you are asking your unit to do what it is not designed to do.
The ice maker is struggling because if it is a cast steel ice cube mold, the heater beneath it is not designed for the current to break the ice cubes free @ -18 degrees F., or if you have a plastic flex ice cube mold it is too ridged to flex enough to break the ice cubes free. Normally your ice maker should dump 8-10 times in a 24 hour period.
A note on food storage. Make sure you do not overload your freezer of fresh food section to the point where food product extends beyond the edge of the shelves.
