  Your Manitowoc Ice Maker might not be operating due to several reasons: * There's no electrical power: Replace the fuse, reset the breaker, or turn on the main switch. * The high-pressure cutout is tripping: Clean the condenser coil. * Energy Saver mode is stopping the ice machine: Reset to factory defaults. * The water curtain is off or stuck open: Ensure the water curtain is installed and swinging freely. * The ice machine is not turned on: Press the power button; the display must indicate “Making Ice.” * For IB Models Only - The dispenser ice level thermostat is open: Adjust the thermostat to maintain the correct dispenser level.

  Peter JonesAug 16, 2025
  If your Manitowoc Ice Maker is producing shallow or incomplete cubes, or the ice fill pattern on the evaporator is incomplete, consider the following: * The ice thickness probe is out of adjustment: Adjust the ice thickness probe. * The water trough level is too low: Check the water level probe position. * The water inlet valve filter screen is dirty: Remove the water inlet valve and de-scale the filter screen. * Poor water filtration: Replace the filter. * Hot incoming water: Connect the ice machine to a cold water supply. * The water inlet valve is not working: Replace the water inlet valve. * Incorrect incoming water pressure: Ensure water pressure is between 20 psi - 80 psi (140 kPa - 550 kPa). * The ice machine is not level: Level the ice machine.

  If your Manitowoc Ice Maker is not releasing ice or is slow to harvest, consider these potential issues: * The ice machine is dirty: De-scale and sanitize the ice machine. * The ice machine is not level: Level the ice machine. * Low air temperature around the ice machine head section: Ensure the air temperature is at least 35°F (2°C). * Fan cycle control does not de-energize condenser fan motor. * The water regulating valve is incorrectly adjusted or will not close: Check for water at the condenser drain outlet in the harvest cycle. Contact a qualified service company to adjust/replace the valve if water is present.

Why won't my Manitowoc Indigo NXT IDT0300A Ice Maker cycle into harvest mode?
- T
  Tara AndersonAug 31, 2025
  If your Manitowoc Ice Maker is not cycling into harvest mode, it might be due to: * The six-minute freeze time lock-in has not expired yet: Wait for the freeze lock-in to expire. * The ice thickness probe is dirty: De-scale and sanitize the ice machine. * The ice thickness probe is disconnected: Connect the probe to the control board. * The ice thickness probe is out of adjustment: Adjust the ice thickness probe. * Uneven ice fill (thin at the top of the evaporator): Verify sufficient water level in the sump trough. Contact a qualified service company to check the refrigeration system.
