The 3 beeps indicates that the freeze cycle is longer than 60 minutes. with the suction pressure at 20, it sounds like low on charge (freon). I believe this is an R 404-A unit. Other things to look for are: Stuck float switch (in the up position), Water valve leaking, hot gas valve leaking, txv not feeding properly, weak compressor. Look at high side pressure too. It should not go below 210 psi during the freeze cycle. Low pressure should be in the middle to upper 40's psi.

Let me know if you need more.

My hoshizaki ice machine KM-900mrf model beeps 3 times and stop making ice. After reset it starts, but stats beeping again after an hour.


Have a look at the side of the evaporator; there is a probe (thermistor) attached to it that tells the control board when to initiate the harvest cycle. make sure it's clean and attached properly and doesn't need replacing. If hitting the float switch initiates the harvest cycle it sounds like you have a blocked/ scaled water tube or switch housing. take off the bottom of the switch assembly (black rubber bit) and clean through to the water chamber. run a cycle of descaler before trying again.

Hoshizaki km-900mah not going into harvest when float switch opens. New circuit board installed still no harvest. I can set an egg timer and manually operate machine but I can't leave it unattended...


Hoshizaki machines must have a very clean evaporater other wise the ice will bind causing a slow harvest. This may be from lime scale build up. "Lime A Way" is recommended for this proper cleaning. After that is done check to see that the water inlet valve screen is clean and that you have a filter installed.
Last check the thermister attached to the suction line.

I have a Hoshizaki model Km-250baf it beeps three times.


3 beeps means it has been in the freeze cycle too long. A stuck float switch can cause this as well as a leaking water valve. Look for that first. Let me know if you need more info.

I have got Hoshizaki Ice Machine which makes three beep sound every 2 second continuously. I turned off the machine. It looks it needs to be cleaned. Can anyone help me to resolve this problem so that it...


I am assuming that it has run two consecutive cycles. I would first clean the machine inside and out. it should drop ice once cleaned, if not then open up the control box and find out which lights are flashing. I am almost certain that once it is cleaned it will drop ice.

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.

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

Hoshizaki ice machine with constant beeping every 3 seconds


Most likely(50% of the times) Your Ice machine need a real cleaning. not just run clean cycle with ice machine cleaner. every 6 month call HVAC-R guys - machine will last half time longer if u schedule proper maintenance with them. I have seen It all: people try to call "friend", or someone who "knows" how this machines work. Real clean would take up to 3 hours for people who know what they doing. Here is one of my videos, when 3 beeps - long freeze cycle is not common and all others would offer You to get a new Ice Machine. Bill to the owner was 950$, New Machine 3450$ plus labour to install 600$.
