What should I do if my Whirlpool Hybrid Electric Heat Pump Water Heater displays the “Edr” error code?

CAUTION: Before attempting any corrective actions, ensure the power to the water heater is turned off at the circuit breaker/fuse box to ensure your safety.

INDICATES: Not enough water in the tank (tank not full).

What To Do:

1. Fill the water heater completely. Open all hot water taps in your home and run them until water flows uninterrupted from all open hot water taps.
2. Ensure there are no obstructions or issues with the water supply to the heater.

If you’ve followed these steps and the issue persists, or if you’re unsure about the process, please contact customer service at 1-877-817-6750 for further assistance.
