How did that person who uploaded the YouTube video figure it out? They didn't have a video to watch. So why couldn't you?

I'd say it's more of specific hypothetical, and I don't understand how one couldn't read about a fuse on a forum or in a manual and diagnose with a DMM. Sure, YouTube is convenient because we are all out of time, all the time.

It's also a further reflection of how helpless we have become with regards to so much of what we rely on.

He spent a month trying different repairs (replacing pump, etc) that didn't work and then finally stumbled onto the electrical relay as the root cause. This is the deep link to the video I used: https://www.youtube.com/watch?v=3Gm_2qISYvk&t=2m41s

Maybe I eventually could have fixed it if I spent weeks on it and replicated all his failures but I didn't have to because ... he uploaded a video to help me. His video was the breakthrough I needed because it identified the particular relay. I actually had to watch more Youtube videos to learn how to actually replace the relay because the board is encased on epoxy resin and I had no idea how to deal with it. Various Youtube videos showed ideas of using an exacto knife and Dremel rotary tool to cut through the plastic case on the other side.

One could hypothetically read the text of fixing a single relay of that particular washer model on a forum ... if... that guy in the vid hypothetically wrote a post on a forum... but he didn't. Sometimes, the mode of sharing is Youtube instead of a forum post. I can't control what other people do.

I did eventually find the official Samsung service manual PDF file and had to download it from some sketchy warez website because end-consumers are not supposed to have it ... but it only talks about board-level repairs ($250) instead of isolated repairs of replacing a single faulty relay.

Without hypotheticals or exaggeration, Youtube has literally saved me thousands of dollars. Showing how to fix cars, plumbing, ice makers, sewing machines, coffee machine, sprinkler systems, etc.
