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

It appears that you have supplied the ice bin model number and not the ice maker numbers. Please double check your unit and see if you can locate those numbers.
Hoshizaki has service info on line in pdf format on servicing and trubleshooting. The machine itself has info on what three beeps message is. Sorry, no pinpoint fix
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.
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.
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
km-450mwb hoshizaki problem is machine strate is ok but to long time ice making , not dropping, two beeps every three seconds what problem i don't no pleas help mi
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?
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$.
