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.
