Door won't lock

Check your door when it closes, it should hit a push-in button above that door latch, at times I have seen the door hinge bent down just some, causing the door not to strike that button dead on.

If thats fine, then its likely to be the door latch assembly or the CCU board bad.

see this causes and fix it. God bless you
Door or Lid Latch Assembly If the washer lid won't lock the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

Door Lock Motor and Switch Assembly If the washer door won't lock the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.
Main Control Board If the washer door won't unlock the problem might be the main control board. This is not common. Normally the problem is with the lock mechanism.

it is very likely the dishwasher is not levelled correctly or the springs in the door are too tight. Refer installation manual to check dishwasher levlelling and door spring is adjusted correctly. Please provide dishwasher make and model if you do not have the installation manual.

Unplug the machine and where the lid is latched you can push a piece of wire wire in the same hole it latches through. The wire will bottom out after in the hole about a inch. Push it slightly farther and try raising lid as your pushing. All the lock is is a metal tab that pushes up and down. After time the enclosure it's attached to splits and makes it fail but it can be opened with whatever goes farther in that hole then the latch itself.

Hi Debi:
First I suggest to try unplugging the unit for 60 seconds to reset the control board. If that doesn't work then open the dispenser and remove the softner and bleach container. There is a cord near the front you can pull to open the door lock. If you still have issues with your door lock after manually opening the door, you will need to order and replace the door latch assembly.

Also I could bet you need to replace your door latch assembly. Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Hello & Welcome to FixYa
This is a common problem that occurs when self-clean cycle is used after a long time or when the oven gets old. Recommended repair is replacing the door latch-lock assembly as the latch mechanism cannot be repaired. Please get back to me if you have any other questions.

Just bang the door again until the error goes away. The door is not lined up and won't latch properly. At least that is what ours does. I usually slam the door on my machine.

Doot lock hook may not be engaging or door lock is faulty- wiggle the door around while pushing on it, check the door hook , replace the electric latch

I would check to make sure the connectors to that door lock are all connected. If they are it's probably the lock/switch mechanism itself. Wow I just checked and they are about $120. The p/n is wh10x10006 You can google around for the best price. Good luck!
