Funny, I hopped on the computer to Google something I want to DIY this morning, but I took this little detour here first (yeah, that doesn't happen often). Good for you for figuring it out. Now that you've had such smashing success with your dishwasher repair, you'll have the confidence to tackle even more repairs, ultimately saving you loads of green soldiers. Wonderful!
Yesterday, DH was trying to fix the automatic sliding door on my van. It only opens intermittently. He learned how to take the door apart by watching a YouTube video, diagnosed the problem, and then Googled the part. He found it on line for $30. I hate to think what a dealer would have charged for the same repair.
