What Attention! Tank not filled! means

On the GE GeoSpring hybrid water heaters with the text-message display, such as the GEH50DNSRSA and GEH50DXSRGA built around 2012 to 2013, the message "Attention! Tank not filled!" means the unit was powered up before it was filled with water. Running the electric heating elements without water will damage them, so the unit sounds an alarm and stays in this warning. You will see the full sentence scroll or sit on the display until the tank is filled and the unit is restarted.

Common causes of Attention! Tank not filled!

  • Whether the tank is completely full of water
  • The cold water shutoff valve position
  • Air trapped in the tank or lines
  • Dry-tank sensing, if the message stays after filling
✓ One safe check you can try

1. Fill the tank completely with water; a hot faucet running steadily shows it is full. 2. Press Enter to stop the alarm. 3. Press Power once the tank has been filled. 4. If the message returns with a full tank, call us.

! Why to stop there
  • If the tank is full and the message persists, the sensing or the control needs a test.
  • We confirm the fill and check the elements for damage from dry running.
  • If the unit already ran dry, the elements are tested before power is left on.
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.

Attention! Tank not filled!Attention! Tank not filled! questions
Why does the water heater warn me about a tank that is not filled?

Its heating elements are made to sit in water. Powered dry, they overheat quickly, so the control sounds an alarm and waits for you to fill the tank.

The tank is full and the alarm repeats. What next?

Let a hot faucet run until the flow is steady, press Enter, then press Power. If the message still returns, the sensing path needs testing on a visit.

Could the heater already be damaged?

If it ran dry only briefly, often not. If it ran dry for a long time, we check the elements during the visit and tell you what we find before any repair.
