Dry Tank Fault

What it means

Dry Tank Fault. The water heater has not been filled with water before powering up; powering up without water will damage the electric heaters (warranty does not cover operation with an empty or partially empty tank). During installation: if the unit is powered on without a full tank, F11 will show in the display.

What GE says to do

Turn off the power, fill the tank with water, then turn the power back on (installation section, page 17). The troubleshooting chart (page 21) says: fill the tank completely with water, press ENTER to stop the alarm, then press POWER when the tank has been filled.
