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

My Hoshizaki KM-500MAE is not producing much ice. I removed the panel and saw a lot of ice built up inside the area where ice usually falls down. There are huge chunks of ice and I have left the machine in the WASH mode to defrost the ice.
What is causing the ice to build up inside the machine and prevent the ice cubes from falling into the bin? There are ice blocks all over on the sides and on top of the metal grills.

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

HOSHIZAKI KM-500MAE - Fillstray then i hear a click after about a minute and then the compressor never kicks on and no icefreezes

any beeping? beeping says what problem it is having.
Reset it while energyzed by pushing the button way back of the control board in the control panel section.
The switch needs to be set to run and valve to normal position, full ice bin sensor may be stuck to full position, exercise the sensor flap.
Post what you tried to remedy the situation for better help ideas. Trouble shooting instruction are included on the machine cover doors.

I worked on a hoshizaki km-500mae when i turn it on the first cycle it makes good ice but after the first cycle it makes little pieces. why?

time the cycle. if it is only running about 5 minutes and going into harvest, look for sump loosing water. Look at where the unit drains (like a floor drain) while the unit is running to see how much, if any water is draining. does not take much to make an early harvest. also, sump may not be filling up completely but with just enough water to satisfy the float.

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.

Remove the cover where the persons finger is and check to make sure that it is not covered with ice. Sounds like your machine iced oup and you will need to clean the coils and possibly replace the thermostat

Hoshizaki ice machine with constant beeping every 2 seconds

turn it off and on and check the drain line and see if its draining water. some times the check valve needs taken apart and cleaned. the problems corespond to water related problems. usually because its taking too long to freeze. good luck
