What FILL TANK! means

FILL TANK! on JennAir RISE and NOIR built-in coffee systems like the JJB6424 means the water tank is empty or incorrectly positioned. Fill the tank with water or insert it correctly, pushing it in as far as it goes. The tank also needs to be clean so the float can move freely, and a sticky float can trigger the message.

Common causes of FILL TANK!

  • The water tank is empty
  • The tank is not pushed in fully
  • The float in the tank is not moving freely because it needs cleaning
✓ One safe check you can try

1. Remove the water tank and fill it with fresh water. 2. Rinse the tank and check that the float moves freely. 3. Push the tank in as far as it will go. 4. Start the drink again. 5. If FILL TANK! stays with a full, clean tank, call us.

! Why to stop there
  • A tank issue is an owner task, and a visit would not be needed.
  • A dirty float is a cleaning matter.
  • A tank that is full, clean and seated that still shows the message needs the sensor checked.
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.
