20 Most Recent Hoshizaki Freezer Commercial Ice Machines - KM900MRH Commercial Ice Machine Questions & Answers

If the Hoshizaki F-450maf ice machine's reservoir tank has no water, you should first check that the machine is properly connected to a water supply and that the water supply valve is turned on. You should also check that the machine's water filter is clean and not clogged. Additionally, make sure that the float switch is functioning properly and that it is not stuck in the "off" position. If these steps do not resolve the issue, you may need to consult the machine's manual or contact a professional for further assistance.

bin stat is what is used to shut machine down. if it goes bad in any way, no power will go to the control board. Start there.

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.
