Jenn-Air dishwasher, control panel or board?

About 3 years old, we’ve never had a problem with it. The last load ran just fine, now we get nothing from the control panel, no lights, no beeps, not functionality. I flipped the breaker off and back on and then verified that the unit was receiving 120V. How can I tell if it’s the panel or the control board? Could it be anything else?

Never mind. Flipped the breaker off for a few minutes and it reset and is working fine.
