Hoshizaki ice machine water overflows into ice bin

My Hoshizaki KM-500mab overfills when the machine starts up and leaks water into the ice bin. The compressor kicks and and the flow of overflow stops. I have checked the float and cleaned it. Checked water inlet valve for blockage. Checked water valve and checked spring. When I opened the reservoir, water leaves the machine, but eventually gets backed up. I stuck a hose down there, water flowed good.

Water in the ice bin could be something as simple as clogged ice bin drain.
The bin is nothing more than a big insulated box
Kinder like cooler, but a drain.

A water drain plumbing problem? It is normal for the machine to flush itself out, of minerals. Drain attached to the machine (ice bin and machine) needs air venting. Clog should be flushed out or the plumbing design is at fault causing back pressure or debris in the line. Algea flushes out easily.

Too high of water pressure letting in more water then it can drain off. Try turning down the water first

SOURCE: Hoshizaki Ice Machine Model KM-500MAF

(Quated From Hoshizaki Technical Bulletin)
An alarm code of 3 beeps
every 3 seconds means that the control board has shut
down on the 60 minute freeze cycle back up timer.

The “E” control board has a 60 minute timer that starts at
the beginning of the freeze cycle. If the float switch fails
to open and start the next harvest within 60 minutes, the
board will automatically start the harvest cycle. If this
occurs in two consecutive cycles, the control board will
shut the unit down on the manual reset, freeze cycle
back- up timer. The yellow fault LED marked “60 min.”
will illuminate. This safety is designed to help prevent a
freeze up of the evaporator.

Once you have identified the 60 minute alarm, there are
several things to check. Reset the alarm by depressing
the white reset button to the right of the fault LED’s.
This must be done with the power “ON”. Now check the
float switch to see if it is stuck in the up position. A stuck
float can occur if scale is present on the reed switch
shaft inside the housing. To check it, drain the water
reservoir, unplug the black float switch connector (K5)
from the control board and check it with an ohm meter
for a closed switch (zero ohms). If the float switch is
sticking, clean it with ice machine cleaner or replace it as
necessary.
An inlet water valve which is slowly leaking by during the
freeze cycle can cause a 60 minute alarm. If the inlet
water valve is stuck wide open, it is unlikely that any ice
will form on the evaporator. Check for a slow leak by
allowing the unit to cycle into the freeze cycle and
disconnecting the hose at the outlet of the water valve. If
water leaks by during the freeze cycle, the water valve
diaphragm is likely damaged or the small diaphragm bleed
port is clogged with scale. Clean the bleed port or replace
the diaphragm or entire water valve as necessary.

(I Recommend to get a refrigeration tech for this part).

Another possibility is a refrigeration system problem. You
should use normal refrigeration diagnosis procedures to
check for one of these problems. If the thermostatic
expansion valve is not feeding properly or the refrigerant
charge is low, the evaporator will not form ice as it should
and a long freeze cycle will occur. This could also be the
result of the hot gas valve not closing completely during
the freeze cycle or if the compressor valves are weak or
inefficient. An inefficient compressor however, will
usually show up first on the KM model through a longer
than normal harvest cycle. This is because of cooler
than normal discharge gas. Use proper refrigeration
practices to repair a refrigeration system problem.
While these are not the only reasons for a 60 minute
freeze cycle, they are the most common and should be
checked to resolve a 3 beep/yellow fault LED alarm.

Always attempt to have Hoshizaki pumps rebuilt when possible. The parts are cheap compared to buying a new pump. Check ebay from time to time I have just started tearing units down and selling the used parts, that are still functional. Sold that pump for $75 last week

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

SOURCE: Ice machine is only making flakey size ice.

sounds like there is a problem with the water in the sump escaping. Sometimes, the plastic grate under the evap plates break and pieces get stuck in the dump valve. It is a triangular piece that the pump attaches to via a hose. It is spring loaded and the pieces prevent it from seating, thus, water leaks into the drain that you will not notice. When the water level in the sump gets low enough, it goes into a harvest and drops small slivers of ice. I'd check that out first.
Hope this helps.

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,

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.

Hoshizaki ice machine model km 900mwh low side suction line has ice building up on it all the way to the compressor


Is it making ice? Frost on this line is not that uncommon as it is colder than the air around it. Make sure you have good water flow over the evap plates. machine may just need a good chemical cleaning.

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.

Hoshizaki Model KM 630 MAE


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.

Model km-250baf hoshizaki with weighed in correct amount of 404a the head preasure risies to over 400 psi i think it is the txv advise me if i am right


There are a lot of variables that cause high head pressure. Be sure the cool ing fan is operating properly. It should come on whenever the condenser coil feels warm to the touch. It will cycle on and off as the pressures change. A clogged up coil will also cause high head pressure. If you don't have sufficient water flowing over the evaporator plate, where the ice freezes, the head pressure will go up. You need to check the low side head pressure as well. Weighing the charge is a good start to charging the machine , but the first question I would ask is why are you charging it? Was there a leak, or compressor change?
If you had a compressor burnout, did you replace tthe drier-filter?If not, it may be stopped up from burnout residue. That will also cause high head pressure. If you did not vacuum the system there may have been refrigerant still in the system before you started the new charge. Check the items I mentioned and see if that helps.

My model AM-50bae ice machine has water in the storage bin,what can I do?


check the bottom of the bin for a drain spout. The drain line may be clogged allowing the water to build-up in the bottom.

If the water is coming down from the ice machine itself, you will need to open up the machine and look inside. Check to ensure the cube guides have not come out of place, that the sump is not overflowing with water, and that there are no loose, leaking, disconnected, or busted hoses.
