I have a hoshizaki ice maker that is giving a three beep code and the compressor will not start. i have cleaned the float and have water to the machine


3 beeps means freeze cycle too long. usually it's a stuck float or a water valve leaking most all the time. A low refrigerant level, weak compressor, bad TXV, or a leaking hot gas valve are usually secondary issues but not very common. In rare cases, the evaporator plates can separate from the refrigeration tubes. look at evap plates at the bottom and top and see if they are bowed or odd shaped.

Freeze back up timer3beeps


signal means freeze cycle is longer than 60 minutes. Look for: stuck float, water valve leaking water into the sump, Hot Gas Valve leaking hot gas into the cold side of the refrigeration system. Start there.

Hoshizaki water dont stop runing


float switch is stuck in the "down" position. The unit goes thru a fill cycle and after 1 minute, the board "Looks" at the float swith to "see" if the sump is full. If float is stuck down, it tells the board that the unit does not have enough water and stays in the fill cycle. The compressor will not come on as long as the machine "thinks" there is not enough water. let me know if I can help further

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.

Iam working on a hoshizaki ice maker, turn it on make one batck of ice, after that, my cooper lines on bottom of coils were warm and o n top od the coil were hot,whar could be the problem?


On Hoshi ice maker, if coils are HOT, it is passing hot gas from compressor into the lines. After the defrost of the first cycle, after this cubes are completely cleared from the plates, the "Hot Gas Valve" should close and the freeze cycle should start over. It sounds that the valve is sticking open and not stopping the hot gas from entering. Look there first.

Unit makes ice,full evaporator,is very slow,maybe 45 mins. from harvest to harvest. Why so slow?


Possible causes are many
Things to check
  • If air cooled, is the condenser coil clean and is the condenser fan running when in ice production ? Is the area extremely hot where the ice machine is located? If water cooled, is there adequate water pressure and is the water regulating valve set properly?
  • When the system switch is in the off position is there any water running ( if so the inlet water valve may be stuck open)
  • When in ice production, is the small tube that feeds from the hot gas solenoid hot? This tube comes from a valve at the back of the unit and feeds over the compressor and into a tee near the insulated Tx valve. This line should be hot during harvest and cool shortly after harvest.
  • Has the float switch assembly been cleaned. this is a cylindrical unit beside the water pump,It can get plugged with minerals and not initiate harvest
  • The system may have a refrigerant charge problem (short) or the compressor may be weak, at which point diagnosis would need to be done by a refrigeration tech
Hope this helps

Hoshizaki ice machine KM500-MAE not sending water to harvest


I would not change the pump. If it runs for 3-5 minutes and stops, it has to be a control. The control board runs the freeze cycle for the first 5 minutes. This prevent "Short Cycling" of the freeze cycle. The board looks at the float after the first 5 minutes for the proper water level but should not effect the pump. If the pump does not run in the wash mode, check out the "Power/ Wash" switch. I would start there before I go spending hundreds on pump motor or control board. You may be able to get by on a $20 fix! Do this and get back to me. We will get it going.

Good Luck

Km 500 kae hoshizaki 3 beeps every 4 second compressor not coming on


put an amp probe on common wire at compressor and see what amps are when it tries to start. 40 to 60 is mechancially locked up compressor. kill power and test start and run capacitors. there is an thermal temp over load on the compressor that opens when comp gets hot from trying to start. gently remove and look for cracks or burned looking. . i saw one this week doing exact same and i have ordered the oem compressor start cap realy and run cap and drier and will put in all new gas. be sure to allow sufficient time when switched to ice for it to get to ref cycle, it may take 5 minutes starting with water purge, then fill, etc. good luck, call hoshizaki dist they are usually pretty helpful if you need a auth service rep in you area. i think they are three years warrantied!
