That dishwasher is a 21 or greater. That's when they dropped the classic design, because the Hobart division of home dishwashers was bought by "Whirlpuddle". I can't see the sump clearly, but the heating element is in the wrong place. Hobart didn't do this.
Also the handles on the cutlery basket are shaped differently than the older ones. It musts be a "Surperba", but the buttons are arranged strangely.
This is probably not a bad dishwasher but after W/P got a hold of them, they started to go downhill. The government started putting restrictions on the manufacturers, and everybody wanted everything for a song, so they sent production to other countries to be built and our jobs and quality went with them. Landfills full of junk appliances. How nice.
Anyway, you have to look for traces of water leaks under the machine, and around the motor and slinger. If it has a motor shaft seal leak, the slinger would have thrown water around under the tub in a circular pattern. It could also have a door gasket leak or an internal leak inside the door, water valve malfunction, clog in hose, damaged or jammed impeller, or an electrical problem. It could be something easy or more complicated. If it's complicated, a service manual comes in handy. It's a learning process. You have to decide if you want to tackle it. Look around - find out how many parts are available for that model.
The tines on the bottom rack are bent in different directions. Look for rust spots on the racks. It gets under the vinyl and corrodes underneath it. It can be repaired with a drimmel tool and the carbon steal brush. Then a couple of coats of JB Weld painted around the polished steal with a short wide stiff artists brush works (a tedious process). Sometimes new bottom racks can be had for around a hundred dollars, if you want to pay the money. Top racks are more expensive.
Personally, I wouldn't do it on any thing less than a KDS-20 through 18. Maybe a 17 or 16. Haven't worked on anything other than a 20.
Just my opinion. Others may feel differently.
