Quiet Parner II will not run at all no lights

Whirlpool quite partner II is totally dead with standing water in the bottom. We have changed the Thermal Fuse and wiring and still nothing at all no power no ligths HELP this dishwasher is only 1 1/2 old of course just past the warrenty date and we have had no issues with at all until now. Just stopped working in the middle of a cycle. Is there any hope to repair that is not going to cost a fortune in a service repair??

Appreciate any help we can get
Thanks
