Broken Ice Maker Easy Ice

Knowing how to reset an ice maker can reestablish ice to your business in rare circumstances if the machine has shut down. Many of the top commercial ice machines on the market will go into a shutoff mode either a Hoshizaki beep code or a Manitowoc error code if they encounter a problem.

Most of the time, resetting an ice maker only succeeds in postponing the inevitable repair you’ll need to get the machine back in working order. However, if you suspect the shutoff mode has occurred in error or due to some of the events we’ll mention, resetting an ice maker can get the machine producing ice for your customers or employees.

If you’re an Easy Ice customer, give our team a call and we’ll help diagnose your problem and walk you through any steps to help get your ice maker working. Inform our team of any symptoms you notice (ie. Water not running, beep codes, alerts on the display, etc.). If we can’t resolve the issue over the phone, we’ll send an ice machine technician to your business ASAP. If there is a problem with the machine, we’ll repair it at no additional cost to you.

Most of the time, ice machines fail due to environmental conditions or ice machine components failing.

As far as components go, there are simply too many possibilities that can lead to an ice machine breaking down. Environmentally, a few problems can cause an ice machine to shut down into a safe mode. They include:

  • High ambient air temperatures exceeding 95 degrees Fahrenheit
  • Low ambient air temperatures below 50 degrees Fahrenheit
  • High ambient water temperatures exceeding 90 degrees Fahrenheit
  • Low ambient water temperatures below 45 degrees Fahrenheit
  • Lack of water flow to the unit
  • Not providing adequate ventilation around air cooled ice machines (at least one foot around all side of the machine is best)

If you suspect your ice machine has shut down into a safe mode due to one of the above environmental issues, you’ll need to rectify them before trying to reset your ice maker.

Ideally, ice makers should operate under the following conditions:

  • The air temperature around the machine should be between 70 – 90 degrees Fahrenheit
  • The incoming water to your machine should measure between 50 – 90 degrees Fahrenheit
  • Water flow to the machine should be following your model’s performance requirements (you can find the water flow your model needs in your Hoshizaki or Manitowoc spec sheet)
  • If you own an air cooled ice machine (the most common type), provide at least one foot of space around all sides of the machine. More is even better!

What Are Some of the Reasons to Reset an Ice Maker?

There are very few scenarios where resetting an ice machine is the best option to get it to start working again. They include times when water or electricity has been shut off due to maintenance, non-payment of utilities, or simply by mistake.

If you believe your ice machine is shut down due to your business’s utilities being shut off, your ice maker may shut down to avoid damage. If lack of water or electricity caused the issue, then it’s likely the machine is working just fine. Resetting the ice maker will start the unit back up safely and reestablish ice to your business.

Depending on the type or brand of ice machine, the resetting process can differ. Below we’ll show you how to reset a Hoshizaki KM cuber, a Hoshizaki cubelet dispenser, and a Manitowoc cuber.

How to Reset a Hoshizaki KM-series Ice Maker

Hoshizaki KM, DKM, and S-series ice machines produce Hoshizaki’s signature crescent ice. These machines are modular-style ice makers that typically sit on an ice bin or dispenser.

Below are instructions on how to reset a Hoshizaki KM-series ice maker:

  1. Unplug the machine and verify there is no electricity to the ice machine (any beeping will stop)
  2. Loosen front cover screw and lift the front cover up and off
  3. Remove three screws from the electrical control panel cover (by on/off switch) and slide the cover straight out
  4. Find the small white reset button on one of the four corners of the control board
  5. Plug the machine back in, and push the reset button on the circuit board either wearing the rubber gloves or using the nonmetallic plastic utensil (a pen can also work)
  6. The machine will begin bringing in water.
  7. Replace the electrical control cover and the machine’s front cover (don’t forget to replace the screws!)
