Energy smart manual shows troubleshooting chart on page 14http://waterheatertimer.org/pdf/Whirlpool-energy-smart-electric-manual.pdf
Initially I would guess the temperature sensor is bad.
However indicator light would flash 3 times.
And since both elements have a temperature sensor, it's unlikely that both would go bad at same time.
That suggests the Self-diagnostic Control Box located on top of heater is defective.
Turn off power at the circuit breaker and see if unit resets correctly.
Manual shows 1-877-817-6750 number for Whirlpool parts and warranty.
Your unit is still under warranty, so control box and other parts should be free.
Keep in mind this water heater requires 10 gauge wire and 30 amp breaker.
If you are running smaller wire or smaller breaker, that could affect long term operation of electronics.
I guess this requirement is so voltage drop from element turning ON doesn't starve electronics in control box
On the control panel, the Red and Black wires connect to 240V from circuit breaker.
Wires appear to pull out of socket using needle nose pliers. It will be important to keep wires in same order.
Take photo of your wiring before disconnecting anything.
To order parts, you must give serial number located on label on side of tank.
Serial number will identify your specific heater to person answering phone at Whirlpool.
Installation part should come with instructions, but ask the person at Whirlpool what steps they took during training. Whirlpool rep might have helpful tip they learned during training.
Add a comment and let me know about your transaction with Whirlpool so I can pass it along.
