GE GeoSpring DEEJS / DFEJS (2015–2016) error code F11
Dry Tank Fault
What it means
Dry Tank Fault. The water heater has not been filled with water before powering up. Powering up the heater without water will damage the electric heaters; the warranty does not cover operation with an empty or partially empty tank.
What GE says to do
Fill the tank completely with water. Press ENTER to stop the alarm and then cycle power when the tank has been filled. If the unit has been confirmed to be filled with water and F11 appears, it may be a false indicator due to unique environment conditions during start up: turn the breaker off for about 10 minutes to allow the water temperature to stabilize, then turn the breaker back on. If the F11 code persists, schedule GE Appliances Service. (See also page 15.)
