What does BUNN CLEAN DUE TODAY mean?
The Ultra NX frozen beverage dispenser tracks its cleaning schedule. When the daily cleaning is due, the display shows CLEAN DUE TODAY. It is a reminder and not a malfunction, and the machine keeps working. The Use and Care Guide lists it in the table of warnings and error messages and gives the action: follow the cleaning procedure on the Cleaning Card, or use the Cleaning Guide on the LCD by holding the Center Dot for 5 seconds. The guide does not say what happens if the cleaning is skipped. CLEAN DUE NOW is a separate message with its own page. Doing the cleaning when the reminder appears keeps the barrel and the product path sanitary and avoids that second message.

- Check the barrel, auger and seals for residue left after cleaning.
- Check the control's clock and schedule.
- Reset the cleaning counter if the schedule is wrong.
- Cleaning the dispenser involves moving augers and sanitizing chemicals.
- The control schedule and clock should be set by someone who knows the settings.
