this dishwasher has push button panel on top of door. when i push the cycle button say "normal", i then push "start" the "normal" button will blink one time to let me know to close the door and it will wash. Now i push the"norma", push "start" and it will not blink at me. when i let it sit for about 30 seconds(door closed or open) the normal light will just shut off . i wonder if this is the push button panel "start"button that is not working any more. please help .

Here is a tech sheet
http://www.servicematters.com/docs/wiring/Tech%20Sheet%20-%208537797.pdf

The usual way to troubleshoot these units is to check the keypad with a meter.
If it is OK then replace the control board.
Still a bit of a crap shoot but your odds are a bit better.

You may want to 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.
