It is exceeding the time to run a freeze cycle and shutting
off on a programmed saftey limit. There are several different
problems that can cause it to do this from a low charge , txv starving, or inefficient compressor or just a dirty water system. you may need a qualified
technician to check it out.

Is this a hoshiziki or a Scotsman? If you pull the front cover off the machine, is the ice being made by a large flat grid, resembling a big waffle? If so there is a contact control that has a probe touching the flat metal panel, this has an adjustment screw on it. If you have a larger type of ice maker that has a couple of vertical rows with tanks on the top draining water down to the bottom, then remove the front panel and to the left bottom, there will be a tubular looking device that has a hose on the bottom and top. there will be 2 screws, loosen them and slide the round thing up or down to adjust the size of the cubes.

Why would a hoshikia 450 mab jump from freeze cycle to harvest cycle without giving iot enough time to makle aload. would it be the cube sizer adjustment or a bad borard?


clean and dry the sensor and restart the machine. Adjust the thickness until the cubes make a plate but break apart when they fall in the storage bin

Ice thickness control


The ice thicknes control is located on the bottom left. it has a wire going
to it and ha a black rubber bottom. depending on the position it is secured.
will determine the ice thickness. loosen the two screws and push it higher
for smaller cubes and lower for bigger. If you are having problems with it.
There is the possibility it is dirty and sticking.

Hoshizaki M# DCM-270BAH-OS runs for days then freezes up evap coil and stops water inlet to evap.


There is a thermostat probe sat on the front of the evaporator to tell the control board when to harvest. Check it is tight in it's holder. Check the condenser is absolutely clean and filters clear. You can adjust the thickness of the cube. set it on the thinnest setting and see if it harvests before freezing solid.

I Have A KM-900MRH Ice Machine Hoshizaky i, recently changed the water pump, and now sims to be that ice is really thin, and is not making enough.


adjust the float (White plastic with black rubber bottom) item next to the water pump. It needs to be all the way down. Loosen the 2 screws and slide it down all the way. This is what controls the size of the ice cube. Other possibility is that there is water leaking our of the sump causing and early harvest cycle to start. Look for both.

Ice Cubes won't drop out


The thickness probe should be approximatly 1/4 inch off of the evaporator.Sounds like you might have loose grids on the evaporator.turn the unit off and remove the curtain.use a flash light and inspect the grids.There should not be space in between the joints,if there is the ice will freeze behind the grids and not properly release when in harvest. Also gently pull at the grids,if they pull towards you or wiggle then they are separating. I have removed one of the grids and had the unit continue to run for sometime until the evaporator could be replaced.The plating being spotty causes release issues as well.Finally check the level of the machine,front to back and side to side.Not being level will also cause release problems

Ice cube shape


hoshizakis make ice cubes depending on the amount of water in the sump. if you are starving for water the sump only partially fills in the fill time allowed . then it makes ice until the water is used up and the float switch drops and the cubes are little slices. you can adjust the size of cubes you want by raising or lowering the float assembley in the sump. if its to low the water rises and the float rises and tells the machine you happy with little slices. if you raise it up to max height you can max fill before float satisfies and max ice cubes. But if you are starving for water the time to fill will run out before the sump fills and cubes will be small no matter where you set the floats assembly. water starving can be due to crud in the water line, to small a water line, most hoshizes take a half inch line ,or a clogged water filter. if you suspect a filter take it out . if fill is drastically improved you need a new filter. be aware that starving for water on a hoshizaki will eventually lead to broken evap plates. big time expensive.good luck. i put in a new machine ruined by starving water and the new one made little chips of ice real quick. i finally pulled the filter out and voila! big cubes and great production.

starving for water. clean or replace water filter or adjust water float assembly that determines how big cubes are. probably not getting abundant water during timed fill sequence. no water equals little ice.
