i suspect a defective liquid line or pump down seleonid coil. just make sure you hear the "click" when it starts up if not the selenoid coils could be defective. also verify that the condenser fan is running,because if not you are short-cycling on high head pressure. please contact if you need any additional info

Always attempt to have Hoshizaki pumps rebuilt when possible. The parts are cheap compared to buying a new pump. Check ebay from time to time I have just started tearing units down and selling the used parts, that are still functional. Sold that pump for $75 last week

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.

Try Rick and Restaurant Parts and More in Ohio for a replacement valve. 1-888-814-1110

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
