My washer out of the blue says that the door is open when it is shut. So I did what I seen on here and checked the striker, then replaced the Door Lock/Switch. When I emailed parts pros and asked if could be the mother board they said just to change the swtich. The striker doesnt look cracked, loose, or missing anything. I accidentally ordered the wrong door lock/switch (which obviously didnt work) then i ordered the correct one per model number and still same error/sounds.
So since the new (correct) switch didnt fix it I am wondering is there a way to reset (if help) or should I look at (repair/replace) the mother board?
We are going on 2 1/2 weeks without our washer and desperately need to get it fixed ASAP. Any help will be greatly appreciated.
Thanks,
Nick

Our Affinity front load washer kept flashing the error code "dr" and beeping 4 times. It did this over and over as long as the power was plugged in. Other online forums say you should replace the door lock mechanism which I did. But when I plugged it back in, the problem came back.

THE TRICK that worked is: you have to break rule number one for working with electrical things and leave the power plugged in! Then open the door and peel back the rubber seal/boot. (You may need to remove a spring loaded metal ring that's hidden inside the groove of the seal.)
Then reach inside to the right. Find the door lock mechanism. Unplug the bottom connector. (The one to the wax motor.) You will hear a clunk sound. The dr code will change to something like "18h" and the darn beeping will STOP. Wait a few seconds. Plug it back in. You'll hear another sound.

If you have long skinny arms, you might be able to do this by sliding off the top of the washer and reaching in.

This won't fix all problems of course, but it's a cheap and easy thing to try first.

Going thru the top is a lot easiest than dealing with seal and putting if back on!
