Troubleshooting:

The "Fill Water Tank" message will appear when the water tank is near empty. Tank will not be completely empty. If "Fill Water Tank" appears on the display, remove the water tank, fill with water and return to the water tank compartment.

1. To open the tank, push the Water button.
2. Pull water tank straight out to remove.
3. Add water to tank as needed.
   • Make sure cold tap water is being used to fill the water tank.
   • Do not use demineralized, filtered, bottled, reverse osmosis filtered or distilled water.
   • For additional information, refer to Convection Steam Oven Water Requirements.
4. If "Please Insert Water Tank" appears, refer to Convection Steam Oven Please Insert Water Tank Message.
5. If the message does not disappear after adding more water, turn the home circuit breaker to the unit off for 30 seconds and back on again. Retest the unit operation.
6. If the unit has not been descaled within last 6-18 months, refer to Wolf Convection Steam Oven Descaling.
