My Frigidaire Dishwasher model #FDB520RHS0 has the lock light lit on the door, and I can't operate my dishwasher. How do I get the lock feature to unlock?
General InformationOn most dishwashers the control lock feature is located on the heat/dry button. You should have a little icon of a lock just below the heat/dry feature. To unlock the console you will need to hold the heat/dry button for 2-5 seconds. The lock feature should unlock the console and the little lock light should go off, and should be able to run the dishwasher cycles. If the control board does not unlock, you may have a bad control board, and it may need to be replaced.
