Took washer apart, put it back together and now it won't start

Go on line for Support and download the manual with schematics.

We would advise you contact the manufacturer of the carseat as the likelihood is that the unit will need to be sent to specialist engineers to inspect and put back together correctly. Due to safety implications of the harness being incorrectly fitted it may not be possible to do this yourself.

Ignore all the other comments, they are wrong.
The feed dogs are driven by the feed driver mechanism, turn the hand-wheel forward and the feed dogs will come up. (Providing you have the feed dog switch to the up position).

Open it back up and check to make sure you didn't accidentally pull one of the cables out.

3949247 is the actual part number for that lid switch, and you won't find a blow out of the thing taken apart because its a molded part and not designed to come apart/

I had the same problem, started filling right away, also when the wash cycle is done, the clothes are wet, it starts to fill again after spin cycle. I intended to buy a load sensing switch the next day, but it was $76 dollars. i removed the switch, gentley pryed it apart, there was 2 small thin brass/copper contact tabs, I bent them slightly to make better contact. I put the switch back together and reinstalled it, put the machine back together, and it has been 3 months with no problems.

It covers your model. Pay attention to the Motor Brushes, making sure
they are maiking contact with the Motor after re-assembly.

Drained the water from the tub into a bucket. Since the water flowed through the disharge tub I knew there were no obstructions in the line. I then took took the discharge pump out and took it apart. Turned out to be a bobby pin in the motor that was jamming the impeller.

Put it all back together and it works just fine. Took me about 2 1/2 hours total to diagnose and repair.
