Hi, welcome to Just Answer. Sorry to hear you are having appliance trouble, I know how frustrating that can be! My name is ***** ***** I look forward to helping you!
If your dishwasher is dead, the control is very unlikely to be faulty. There is a fuse that is quite common to open, see number 6 in the diagram at the link below.
That fuse is mounted on the control (number 10), and can easily be tested by measuring continuity through it. If it is open, it is, of course, faulty. If you have no meter to test with, I would replace it. Make sure to replace all parts in the kit.
The link below is to the part you will need from a highly recommended company rated A+ with the Better Business Bureau. They offer a 100% money back guarantee, EVEN ON INSTALLED ELECTRICAL PARTS, for an entire year! They are the only company to allow returns on installed parts for a refund and offer a FULL ONE YEAR WARRANTY!
The video at the link below shows how it is accessed and replaced!
