My dishwasher quit near the end of the cycle and will not power up at all now. I have verified that power is getting the latch and the thermal fuse has continuity. I can't find a wiring diagram or a schematic of the board online. The dishwasher appears dead. Any ideas?

Here are your parts
Replacement parts for WHIRLPOOL DU943PWKQ0 | AppliancePartsPros.com

Here are a couple tech sheets. I do not know why there are 2 (could be for different serial numbers) so thought I should include both

When you checked the thermal fuse did you remove it from the unit. This prevents reading an alternate/parallel circuit path.

Check that the unit is getting power. A few months ago I ran into a period where a few people had problems with the wire nut connections.

Check that the door switches are closing.

Thank you for your help, the schematics are what I was looking for.
I did remove the thermal fuse to check it and it checked fine (although it appeared as though it had been hot as it was a little dark on one side). As well, power is getting to the board when the door switches are closed.

Can the board be repaired if it is the problem or does it need to be replaced?

The board must be replaced.
Manufacturers do not release electronic schematics for the boards.

The thermal fuse should read 0 ohms.
