Hoshizaki IM130 ice machine that will not freeze,the coil wire (i think)used to heat up and now not any more? Have pressed the reset button and the same issue remains, water running just not freezing.

SOURCE: Hoshizaki ice machine model KM-450MAB water runs

Hoshizaki machines have a water inlet valve that can stick in the open position. This will cause the machine to do silly things. If you can turn the machine off and you can still hear water running, the valve is stuck open. It is an easy fix. Water valve only has 2 wires going to it and 2 water lines. One inlet and one outlet. Just turn off water and kill power at the breaker before doing any work.

Hope this helps and good luck.

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

you can replace the housing only, Check with your local Hoshi supplier for parts. Start there as a new pump is very pricy.

cycle is, fill cycle for 1 minute first. If there is not water entering the unit when first turned on, look for that issue. Water turned off, water valve not working or some restriction, clogged water filters, etc. That is got to happen first. Don't over look the bin stat being bad. Nothing happens if teh bin stat is bad. It sends voltage to the control board that runs the unit.

if the machine is freezing up completely the evap coil could be damaged.
the float valve could stuck or the harvest thermister may not be reading correctly.
