Child lock won't disengage
 

Child lock will not disengage. How do I troubleshoot if its the sensor pad or contol panel?:confused:

Have you tried removing power from the unit for an hour or so, to see if it will reset?

I have tried to find a pinout for the keypad for you but so far have not had any success. You really need that so the keypad can be checked with a meter to confirm that you have a stuck key.

Here is a tech sheet which may be of some use.

Disconnected power for one hour, the unit started up and i ran a load. It got about 2/3 done and the unit went off. I tried restarting and the child lock engaged. I pushed cancel and after about 2 minutes the washer started to discharge water.

I disconnected power again to reset it and the dishwasher started to work. Do you think moisture is getting into the keypad/circuit board?

Would be worth opening it up and taking a look.
