Every so often, a commercial ice machine may run into problems. Many commercial ice machine equipment manufacturers design fail-safes and alerts to help users and technicians diagnose problems quickly. Manitowoc NXT ice machines use a series of notifications that inform ice machine owners in Kansas and Missouri to potential problems within the unit. There are 36 Manitowoc fault codes that cover a range of potential problems that can occur.
Note that this list is only for reference. If you’re an Ice Masters customer and have received one of these notifications, call us as soon as you can. We’ll send one of our qualified ice machine technicians to your Kansas or Missouri business as soon as possible.
Please do not attempt to reset the machine or fix the issue yourself. Manitowoc ice makers are complicated machines. Attempting to fix the machine yourself could damage the unit.

Our indigo nxt ice machine always E01 code and E20 but the machine is brand new almost a week of purchased?
Hello Jeffrey,
Thanks so much for reaching out to us. With those alerts, The E01 is a long freeze alert and the E20 is a water fault. Check to make sure your ice machine is getting plenty of water and also make sure the water level sensor located in the reservoir area is mounted all the way up. If the water level sensor is lower than it should be, the machine will not have enough water to make a batch of ice and will create both of those error codes. If you’re still experiencing problems, reach out to a technician for professional service.
Thanks!
