I bought the door latch OEM part, followed the video linked in the part description and it was a breeze. It is worth noting that I am a Master Diesel Mechanic so tools and taking things apart are no strangers to me. If you're not even slightly mechanically inclined, call someone who is...a pro repairman, a friend who is a mechanic, heck, even a DIY'er with basic skills can do this repair but don't hesitate to ask for help if you even think you might need it. A favor is cheaper than buying a new washing machine. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
