I have a KitchenAid Superba Dishwasher that I bought used a year or so ago. I did not get any paperwork with it.
The control panel is going out in it (Start button will not work) so I need to order parts for it. I can not find the model number anywhere on it. It doesn't look like the label has been removed. All I can find is the quick use description manual sticker on the inside of the door is this number:
8531654

On the side of the door there is a number stamped into it that is:
020022015

There is nothing on the kick-panel as well.

Any suggestions in find which model number this is? I can send pic as well.
Thanks!

Your best bet is to open up the door and see if there is a part number on the control board the look this number up on the AppliancePartsPros website.

You may want to try the following, especially f there are 4 or 4 keys that do not work. Most keypads/control panels use certain pinouts/tracks as common to a number of keys.

Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector. Use electronics contact cleaner or isopropyl alcohol.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
