If you see a "#900 Cooler Off" dialog appears on the touchscreen, press "Continue". If the error message did not pop up again within one minute, the machine should operate normally.
Check if the water level of the cooling tank is at least half full.
- If the error message pops up again, please refer to Water Cooler Maintenance, change the water and try again.
- If the solution didn’t work, contact FLUX Support.
