This 13 month old diswasher will not respond to the start button. When I push the heated dry and normal wash buttons twice in succession, the wash and clean buttons light up, and a 5-10 minute cycle will run. Do I need a new control panel?

Although your model number was short several digits I think the above is the correct tech sheet.
The problem may be the control panel (keypad) or the control board.
The normal way to troubleshoot is to check the keypad with a meter is it checks out OK then order a control board.
Still a bit of a crap shoot but your odds are better.
If a number of keys do not work and use a common line then try the following.
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.
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.
