Try cleaning the condensor coils. Check the fan blowing across them. When the compressor is running the fan should be too.

Ice machine not making enough ice


Need some more details. Size of cubes too small? Batches of ice take too long to make? (Over 45 minutes?)

Steady beeping on hoshizaki ice machine


You have a relay or starter going bad. It definitely needs servicing. I am assuming you have called tech. I would turn it off until you get it fixed even if it is still making ice. This may indicate something is seriously wrong or about ready to shut down.

I have a model # f-450 mah ice machine. After the bin gets full of ice it stops making the ice but the water continues to run and runs out of the machine. Any ideas on how to stop this?


Sounds like the water valve is stuck. Probably needs replacing. Turn off water after machine shuts down and see if water stops. If it does, water valve is most likely the issue.

The machine is making ice, but will not release ice in order to make another batch.


harvest cycle is done by hot gas entering the evap AND water being let in. If both of these are functioning correctly, the machine may just need a good chemical cleaning. One of these 3 things are most likely the cause.

KM450MAB my machine makes a batch of ice then goes into harvest cycle and dose not come out of it, it gets realy hot. What can be the problem?


Probably the suction line thermister, this sensor should signal a timer in the main control board to initiate harvest. If the thermister is OK than there may be a problem with the control board

I have a Hoshizaki Model KM500MAE that keeps freezing up. What can I do to stop this problem


several things cause freeze ups.
If you have water filters on the water system, be sure they are not restricting the water flow. water flow pressure should not go below 20 psi.
The bin stat may not be shutting off the unit properly. It should shut off machine within 10 seconds of ice making contact.
Make sure the float switch is not dirty. Be careful when cleaning. Fragile
Make sure water pump runs the entire time it is in the freeze cycle.
Be sure the evaps are clean. Ice cubes will hang on if not clean.
Water solenoid has a screen where the water line screws on to it. Turn off water and check screen to be sure it is clean. This can restrict water flow.
Make sure water valve closes all the way. Turn machine off and see if water is still running. Valve may be leaking water thru.
Dip switches on the board, #1 and #2. Turn them both on and it will change the defrost time to 3 minutes. If both are off, they are set on 1 minute.

Hope this solves your problem. Let me know

Small production of ice? What should be the normal production of ice?


The way I understand how Hoshizaki machines work, the model number is usually what the unit will produce, in pounds of ice. Their manual states: "Approximate production/ 24 hours @ 70 degrees air/ 50 degrees water (incoming)" So, yours should be producing 450 pounds a day, approimately. Since I can not pin point your exact model, I found one that is close. It states: "Ice Production per cycle: 6.6 pounds, 360 pcs." Again, it is not you exact machine. Their web site does not show this model either. So this is the best info I can get for you. Hope this helps.

My ice machine does not make enough ice


Check the water filters first. Then check the condenser coils for dust and dirt. Determine which way the air goes thru the condenser coils and check on the side the air goes into. There are coil cleaning sprays that work good. If it is still slow, it may need gas. That will require a service call from a technician.

Bin control


The bin control shuts it off when the ice bin is full. Without a bin control it should keep making ice and never stop.
