What GROUND TOO FINE ADJUST MILL INSERT WATER SPOUT means

This longer message on JennAir RISE and NOIR built-in coffee systems, such as the JJB6424, appears when the water tank was removed during coffee runoff or there is air in the waterline. Put the tank back and press OK. The display will show HOT WATER and dispense hot water, after which the system is ready for use again. Replace the tank and the system recovers by itself.

Common causes of GROUND TOO FINE ADJUST MILL INSERT WATER SPOUT

  • The water tank was removed during coffee runoff
  • Air is in the waterline
✓ One safe check you can try

1. Put the water tank back in place and push it in as far as it will go. 2. Press OK. 3. Wait while the display shows HOT WATER and the system dispenses hot water. 4. When it finishes, the system is ready. 5. If the message returns, call us.

! Why to stop there
  • Replacing the tank is all that is asked.
  • Pulling the tank during brewing can introduce air again.
  • Repeated returns point to the waterline and need inspection.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.
