    As part of the EverCheck System, the beeps are to help diagnose problems with the machines. Built-in safeties shut down the unit and have alarms as listed below:

    Number of Beeps Every 3 Seconds Type of Alarm and Notes
    1 Beep High Evaporator Temp. (temp > 127*F/ 53*C)
    Check for harvest problem (stuck HGV or relay), hot water entering
    unit, stuck HM, or shorted thermistor.
    2 Beeps Harvest Backup Timer (harvest>20 min, 2 cycles in a row)
    Check for open thermistor, HGV not opening, TXV or LLV leaking by,
    low charge, inefficient compressor, or WRV leaking by.
    3 Beeps Freeze Timer (freeze > freeze timer setting for two cycles in a row)
    Check if float switch stuck closed (up), WB leaking by, HGV leaking by,
    PM not pumping, TXV not feeding properly, LLV not opening, low
    charge, HM not bypassing, or inefficient compressor.
    To reset the safeties above, press the "ALARM RESET" BUTTON
    WITH THE POWER SUPPLY ON.
    6 Beeps Low Voltage Red LED turns off if voltage protection operates. The control voltage
    7 Beeps High Voltage safeties automatically reset when voltage is corrected.
    At startup, a 5 second-delay occurs while the control board conducts an internal timer check. A beep occurs when the control switch is moved to the "ICE" position. www.hoshizakiice.com

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$.

I believe if you remove the thermostat wires and put them together and retry it you'll be making Ice, then get you a new thermostat. Please rate me accordingly and good luck.

Why isn't my Hoshizaki km 630 mkh ice maker not making any ice?

that could be a number of problems..is it making any beeps or flashing lights on the circuit board? Have you tried to reset the circuit boards reset button with the machine on. ? If the machine seems totally dead then the bin thermostat is most likely the problem..

3 Beep Warning

Staying in the freeze cycle too long. Usually about an hour. Several things can cause this. Look for water running even if machine is off. Possible stuck float switch. And more.

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.

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.

KM-500-MAE Problem huge cubes,alarm code 3-beeps

excessive freeze cycle=60 minutes. In almost every case, it's the water valve (sometimes called the fill valve) is leaking water continually into the sump. Turn machine off and see if you can still hear water running into the unit. If so, it the valve leaking. Just replace it.

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
