Recently our dishwasher hasn't been easy to start. I've been able to start it by pretending it was locked and holding the button for a few seconds and then it would start - the lock light wasn't lit. Now the locked botton is lit, but holding the button doesn't unlock it. I didn't know if I needed to replace the circuit board, or the push button control or it there was a simple fix. Thanks, Dave

First try to get rid of the lock. See page B-9 in Operators Manual

Next thing I would try is disconnecting power from the unit for half an hour or so. Sometimes the electronics can lock up, the above may reset them

Next try the diagnostics

Next try cleaning the ribbon cable re:Control Panel
RIBBON CABLE CLEANING
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.
