My washer is in lock mode and I can't open it. Is there a way to override the lock command and open it?

This has happened to me twice. Both times I found the drain pump seized up with
1st time) The right rim from a pair of reading glasses
2nd time) A plastic toothpick
Both times the object was in the discharge port of the pump. You can see this by lifting the check valve with the pump removed. Removing the pump is simple. Unplug the washer. You have to remove the drain line from where its attached to the rear of the machine (one screw) to remove the rear access panel which slides into upper and lower slots. You will see the pump with an inlet and discharge line attached. The lines have simple squeeze clamps. When you remove the lines, you will drain the wash basin so have towels and a squeegie handy. Remove both lines and wait until the basin drains. When it stops draining remove the pumps electrical connector by squeezing the release catch on it while pulling it. The connector can only go on one way. Remove the 3 hold-down bolts on the pump baseplate. Remove the pump and lift open the discharge check valve and you'll find something there I guarantee it. Remove with needle nose pliers and re-assemble in reverse order.
This is actually a good design because the computer protects the pump by sensing a higher than normal current draw when foreign debris gets jammed in it. It will trigger the ND (No Drain) code and sometimes lock the door. Always check this first before you call the expensive repair man. If its not a jammed pump it will most likely be the control panel/processor. Good luck and always clean out pockets before loading the washer to prevent this,

Your water pump probably has debris in it. Remove the back center cover. The water pump is right there. Thread the drain line back through the machine and put the end in a bucket on the ground, most of the water will drain. I used towels to deal with the rest. Remove the water pump and open it up, I found a quarter. Reinstall and if you found debris the machine should work. It took me 1/2 an hour to do this, not worth calling for service.

Take out the bleach and softener tray (it just lifts out, angle it a little) and unscrew the 4 bezel screws and take out the bezel. You will find a red or green plastic pull line that is supposed to release the door. You may have to "man-handle" the door a bit and pull hard on the line before it will release. Once you work on the door release mechanism (I had to replace the wax motor again, even though it was the "upgrade" black plunger type) I recommend shooting a little silicon spray on the white plastic moving parts of the locking mechanism to get them to move more easily.
This is true on a Maytag Neptune MAH3000AWW front loading washer. Mine is 11 years old, and had the initial wax motor work done at 7 years.

1. Remove the lower panel under the door by loosening the three screws under the bottom edge on the front of the washer. HINT: If you prop up the front feet of the washer with some small blocks of wood, this will make access to the screws much easier.
2. With the screws removed, the lower panel should drop down then come off. If the panel sticks, a light tap on either side will knock it loose.
3. Reach your hand up inside the washer behind the front casing on the right-hand side. This is where the door latch assembly is located.
4. At the bottom of the door latch assembly is a small pull tab. This is the manual release for the door. Pull the tab straight down and the door will come open.

Sometimes these doors will not unlock for whatever reason. If there are no error codes being generated, this could have just been a momentary glitch. If you see "Fdl" or "Fdu" error codes, these are usually indications of a failed door latch assembly and will require replacement.

these units have had alot of problems especially if it is on a pedistal ...they won't admit this is a problem but i have been a lg servicer for over 4 years now and see it everyday ...the unit has a stator on the rear of the tub and on the stator is a device called a hall sensor that goes bad very often... it is what controls the spped and balance of the tub..if the load starts getting unbalanced the hall sensor will tell the motor controller to slow the speed down... most likely this is your problem.... good luck please vote
