:confused: OK my dishwasher started this today. Some of control panel lights don't all work. Also when I press start the unit won't start. I turned off power for a few minutes and rechecked and it allowed me to do the rinse only cycle. But only once . I don't know how to tell if it is the control panel or the control board.

See the attachment for the tech sheet

The usual way to troubleshoot is to check the control panel/keypad with a meter. See the tech sheet for the keypad pinouts.

If the keypad checks out OK then replace the control board. Still a bit of a crap shoot but your odds are 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. 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.
