Without a model number I can only give you a generic answer which is to look under the top cover or inside the lower service panel for tech notes that will tell you how to do some diagnostics and maybe generate some error codes. The door lock mechanism sounds like a likely cause.

Ok, good, the tech notes should be inside the lower service panel and they should enable you to test the door lock mechanism and the main board.

Have you pulled the tech sheet? If so did you run a diagnostics? Also see what error codes are coming up.

Tech sheet in a plastic zip lock style bag, attached to the inside of the right or left wall.

note: the washer must be empty and the control must be in the off state before pressing the touch-pad sequence to start the test.

1. close the door.

2. select any one key (except pause/cancel) and follow

the steps below, using the same key (remember the key):

press/hold 4 seconds

release for 4 seconds

press/hold 4 seconds

release for 4 seconds

press/hold 4 seconds

3. Upon release, all console led lights will turn on for 5 seconds.

4. If there are any failure codes, they will be displayed in the estimated time remaining display.

Note: this program recalls the most recent failure code first.

press the same key to advance to the next failure code.

(if the console doesn’t change then, the same failure

code was stored multiple times.)

if there aren’t any more failure codes, all the lights on the

console will turn on for 5 seconds.

Following this the washer will begin a diagnostic test, you may cancel if you wish by pressing the pause/cancel button.
