Whirlpool DU945 Dishwasher won't turn on but has power

Is your dishwasher hard wired into the house power system ... or plugged into a wall outlet under the kitchen sink?
You mentioned you turned off the power ... how? via the circuit breaker or disconnecting it from the wall? If your unit is plugged into an outlet (and you depowered by cutting the breaker) ... I would check the cord and outlet .. it might be as simple as that.
If that is not the problem ... trying a reset.
Below is a generic one for Whirpools which may work on your model
To reset it, you will have to have the door open. It can not be latched. Press "Heated Dry," "Normal," "Heated Dry," "Normal" within three seconds of the first pressed button. Now close the door, this should reset your dishwasher.
Good luck on your troubleshooting!

Burnt out control panel most likely.

All you can do is turn the power off at the power point, leave it for a few minutes and then switch the power back on.

Control panel. Try to push cancel button to see if it resets.if not google it and they will walk you through it.

could be a fuse in control panel or a bad circuit board

Sounds like your Touch Pad on the Control Panel is defective.

You can try and remove the 120 Volt AC power from the Dishwasher by turning it off at your Main Electrical Power Panel with the Circuit Breaker (15 or 20 amp) labeled: Dishwasher .

Leave the Dishwasher turned "Off" for 10 minutes. This will allow the control circuits on the Dishwasher to reset. Turn on the Dishwasher and press Cancel and attempt to Drain the Dishwasher. If this works...then try to enter a Rinse Only cycle and if that works... then attempt to enter a Wash Cycle.

If you still have your original problems then you probably have a defective:
(1) Touch Pad Assembly (or possibly a defective)
(2) Electronic Control Module (ECM)

you may have inadvertently set the lock on function..
check this out from your manual...
