Manitowoc Error Codes

Ice machines run into problems from time to time, which is why manufacturers build service features to help users and technicians diagnose problems quickly. Like Hoshizaki beep codes, Manitowoc NXT ice machines have a series of notifications that inform users of potential problems. There are 36 Manitowoc error codes that cover a range of issues that occur within the unit.

This list is only a reference. If you’re an Easy Ice customer who is experiencing one of these Manitowoc ice machine light codes, call one of our helpful service representatives as soon as you can. We’ll send one of our qualified ice machine technicians to your establishment as soon as possible.

Do not try and reset the ice machine or fix the issue yourself. A Manitowoc commercial ice maker is a complicated piece of machinery and you could risk damaging the unit.

    1. Hi Rob,

      The machine has activated an alert and a technician should be called. It may be as simple as a maintenance issue but could also be something more significant. There are a lot of reasons this error message could be occurring, so make sure to give your local ice machine technician a call to help you find a solution.

      Thanks!

  1. If my ice machine has an error message of “E08 TXV Fault”, what does that really mean? Do I need to have my machine serviced, or is it a temporary issue? I pressed the power button and the machine started making ice again after about a day, but do I need it serviced and what might be the main issue? Why would we have gotten this error message?

    1. Hi Ray,

      Your Manitowoc ice machine uses 4 different thermistors that measure different temperatures. This error could be a thermistor failure, which would NOT keep the machine from operating, or it could very well be a refrigeration system error. I would recommend calling a technician to look at the machine. If it is a refrigeration problem, it is usually consistent and will give another error code. There are a lot of reasons this error message could be occurring, but the best way to accurately diagnose your problem is to call an ice machine service technician.

      Thank you!

    1. Hey Michael! Thank you for reaching out!

      I’m sorry to hear your machine is giving you trouble. It’s definitely best to call a qualified ice machine technician – especially if you notice performance issues with your ice machine. This error code can have many root causes. For example, it could be a switch failure, a fan motor failure or a dirty condenser in a hot environment. An ice machine technician will have to run a series of tests to see what’s causing the issue.

      Thanks!

      Thanks!

    1. Hey Allen. Thanks for reaching out!

      I’m sorry to hear your machine is giving you trouble. The HPCO is called “High Pressure Cut Out” and is a safety device connected to the refrigeration system. This is an alert that would require a service technician to diagnose the reason for the alert. We highly recommend you give your local Ice Machine Expert a call.

      Thanks!

  2. My Manitowoc Indigo NXT is showing a E2 and a E9. I found what they mean but what is causing this. The ice machine was bought new and was installed about 6 months ago

    1. Hey Tony. Thanks for reaching out!

      I’m sorry to hear you’re having trouble with your machine. The E02 error code is a long harvest cycle and the E09 error code is a refrigeration component failure. The E09 could cause an E02 with an abnormal ice formation. We highly recommend you give your local Ice Machine Expert a call to confirm system operation.

      Thanks!
