harvest cycle is done by hot gas entering the evap AND water being let in. If both of these are functioning correctly, the machine may just need a good chemical cleaning. One of these 3 things are most likely the cause.
Freeze cycle too long. Usually about an hour. Many things can cause this. Look for water running even when machine is off. Stuck float switch causes this. may need a tech to check things out.
If unit never enters the freeze cycle, usually it is a stuck flow which located in the front of the machine. White plastic with a black rubber boot on the bottom. May need cleaning or replacing. You have to drain water out of machine prior to removal.
If you are turning off power, yes this is normal. If it beeps at the end of a cycle, this is not normal. One beeps means the evap is getting too hot. May have hot water entering the unit, or several other issues. May need a tech to check the unit out.
IF you are talking about a freezer, make sure the unit is level as the condensate pan may be overflowing. Also, if the door does not seal properly, it can cause "Sweating" as cold air is escaping and causing condensation at the door. Start with that first.
On Hoshizaki freezers, it has several items that can cause this. Check to see if the heater in the evap are heating up when in defrost. Older machine can force a defrost by just unplug and then plug back in to outlet to do this. There is a "Klixon" type thermostat that disconnects the heaters in case of an overheating condition. These go bad fairly often. Make sure the door closes and seals. Be sure not to do anything that hampers air flow over the evap.
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.
Check condenser coil which is the coil on back with fins, sometimes with metal.mesh filter. If dirty or clogged up clean filter, blow out with air or brush and rinse out, careful not to bend fins. Sounds like issue to me. Unless the dump valve may be leaking by
hoshizakis make ice cubes depending on the amount of water in the sump. if you are starving for water the sump only partially fills in the fill time allowed . then it makes ice until the water is used up and the float switch drops and the cubes are little slices. you can adjust the size of cubes you want by raising or lowering the float assembley in the sump. if its to low the water rises and the float rises and tells the machine you happy with little slices. if you raise it up to max height you can max fill before float satisfies and max ice cubes. But if you are starving for water the time to fill will run out before the sump fills and cubes will be small no matter where you set the floats assembly. water starving can be due to crud in the water line, to small a water line, most hoshizes take a half inch line ,or a clogged water filter. if you suspect a filter take it out . if fill is drastically improved you need a new filter. be aware that starving for water on a hoshizaki will eventually lead to broken evap plates. big time expensive.good luck. i put in a new machine ruined by starving water and the new one made little chips of ice real quick. i finally pulled the filter out and voila! big cubes and great production.
I expereinced the same problem and the only solution I could come up with was to have the gear fabricated. I made a few fro backup. I haven't used any in the two years since i fixed mine. I can sell you a replacement gear or you can send me the gear box and I will install the new gear for you. This same gear box is used in a number of Hoshizaki flakers. Typically symptoms are noisy gear box and jerky auger, or motor spinning but no Auger rotation. Cause is typically scaling/ calcium build up in the evaporator tube. The extra torque stips the gear.Call me if I can help James 580 799 2873
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?
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.http://www.hoshizakiamerica.com/techtips/Pdf/All/tips105.pdf
