# Issue 1. Ice Maker Not Making Ice: First Things to Check
Nothing is more frustrating than discovering your Hoshizaki ice maker is not making ice right when demand is high. Before you call for professional help, there are a few basic checks you can perform:
-
Power supply and connection issues: Ensure your Hoshizaki ice maker machine is properly plugged in and has a viable power source. Check for tripped breakers or blown fuses. Many issues that appear to be complex stem from simple supply interruptions. Inspect the power cord for damage, and verify the electrical outlet is working using another appliance.
-
Inspecting the Hoshizaki ice maker reset button: Every Hoshizaki commercial ice maker is equipped with a Hoshizaki ice maker reset button. Sometimes, a quick reset can fix minor electronic glitches or restore the machine after a power interruption.
-
Faulty bin switch or full bin sensor: Modern Hoshizaki ice maker units have sensors that halt ice production when the storage bin is full. If your Hoshizaki ice maker is not making ice, check if the bin switch or sensor is stuck, dirty, or malfunctioning. Clean the sensor gently and make sure nothing is blocking or pressing against it.
# Issue 2. Water Supply and Pump Problems
A continuous and clean water supply is vital for your ice maker machine. If your machine struggles to make ice, the issue may lie with its water source or internal components:

Water line obstructions: Clogged or kinked water lines can cut off supply to the Hoshizaki commercial ice maker. Inspect the water hose for visible blockages or damage. Ensure the water valve is fully open and that water pressure is sufficient.
-
Functioning Hoshizaki ice maker pump: The Hoshizaki ice maker pump is responsible for circulating water during ice production. If you hear unusual noises or see no water movement, the pump might be faulty. Diagnosing a Hoshizaki ice maker pump issue typically involves checking for leaks, vibrations, or electrical faults.
