I went out on a service call for this dishwasher yesterday. The complaint was that the door latch was broken and the child lock light was lit. I temporarily rigged the latch to work until the replacement part came in but that left me with the problem of the child lock still engaged. The mini-manual for this dishwasher is located behind the kick plate. The mini-manual revealed that the child lock (called a control lock in the manual) can be disengaged by pressing and holding the air dry button for four seconds. So now the customer can run the dishwasher with the rigged door latch until I can properly repair it later this week.
