GE electric water heater displays E8 and heating is disabled.

Safety: Turn OFF power at the breaker immediately if the tank may be empty.

Steps to address E8:

• Verify water supply: Ensure the cold water shutoff valve to the heater is fully open.
• Check for flow: Open a hot water faucet in the house. A strong, steady stream indicates the tank is full; sputtering or no flow suggests air or low water.
• Bleed air: Leave hot faucets open until all air is purged and water flows smoothly.
• Inspect dry-fire sensor: Some GE models use a sensor near the element. Check its wiring and connection to the control board.
• Reset and test: After confirming the tank is full, restore power and see if E8 clears. If it persists, the sensor or control board may be faulty.

Warning: Never energize elements in an empty or partially filled tank; this will destroy the elements.
