I have a Hoshizaki KM-250BAF that is making 3 beeps then pauses and them makes 3 beeps again. If I unplug the ice maker and plug it in it continues to make the 3 beeps. The manual does not mention anything about beeps. Can anyone help?

SOURCE: My Hoshizaki KM-500MAE has ice built up inside the machine

If this unit is iced up this bad, when it goes into the harvest mode, if it has hot gas defrost or electric grid, its not working, The ice will continue to build up all around the coil, flaps, everywhere there is a place for ice to build up. When you defrost it, it will continue to do this. With out service gauges to check this unit when it goes into harvest mode you are not going to find the problem. I hate telling you this, but some things you cant check without special equipment and I know you are trying to save $$$ as we all are. You will need to call a tech out to install his gauges to do the internal checks on the unit and use his electrical meter to check other componants. Please let me know and keep me posted.
Sincerely,
Shastalaker7

SOURCE: Hoshizaki KM-900MAH Ice Maker it sounds like it is

Do you hear the machine cycling like normal but just not dropping? Could be the hot gas solenoid. If you never hear it trying to drop that could be anything from a dirty condenser to dirty plates to bad ice thickness control. Run some ice machine cleaner through it and blow the condenser out.

SOURCE: Hoshizaki KM-500MAH is making sliver/chip ice. I

just to let you know you need to use nickel safe ice machine cleaner. and i hate to tell you this but if you are seeing silver chips in your ice your evaporator is shot. even if it is under warranty they will not give a new plate just for the reason of not using nickel safe cleaner. hope this helps you. i have seen this many times as im a service tech. alot of restaurant owners use coffee cleaner and also destroy their plates

Look for a stuck float switch. unit fills with water for 1 minute, then the board "looks" at the float to "see" if there is enough water in the unit to run. If float switch is stuck down, it tells the unit there is not enough water and the unit stays in the fill cycle causing the sump to overflow and send water down the drain constantly. Compressor will not run till the board senses that there is enough water to run.

Why did my hoshizaki ice machine stopped making ice?


bin stat is what is used to shut machine down. if it goes bad in any way, no power will go to the control board. Start there.

The ice maker make too much ice


Too much ice is usually and indication that the bin thermostat is not functioning correctly. It has either come out of it's holder, is not calibrated properly, or has lost it function and needs replacing. The thermostat "Kills" power to the control board when Ice comes in contact with it and shuts the machine down. Hoshizaki says it should happen within 6-10 seconds of ice contact after the end of a harvest cycle. I would start there first.

Hoshizaki km-900mah ice maker won't start the freeze process


cycle is, fill cycle for 1 minute first. If there is not water entering the unit when first turned on, look for that issue. Water turned off, water valve not working or some restriction, clogged water filters, etc. That is got to happen first. Don't over look the bin stat being bad. Nothing happens if teh bin stat is bad. It sends voltage to the control board that runs the unit.

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.

Hoshizaki ice maker am-50bae . Made ice regularily--- filled ice bin half way...next day-- all ice melted away with no more new ice? next day shut off for 3 hours now o new ice.


make a few quick checks. If there are water filters on the system, be sure they are not restricked. Could be clogged. Next, check the bin stat. It usually is mounted in the ice bin. If it breaks or goes bad, it shuts down the machine. Start there and let me know if I can be of any further help.

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

ICE MAKER WILL NOT MAKE ICE


Check for power supplied to unit.

Check that the bin stat has not been broken and has no ice sitting on it. If the bin stat is clean and doesn't appear to be broken, you can attempt to jump out the bin stat and see if the machine comes on.

If the machine comes on, replace the bin stat. If the machine does not come on and you have shut the machine off and back on, then you will need to call for service.

The check valve is a common issue with the Hoshi line-up. If you know where this is, take it apart, clean it, and re-install it.

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.
