>Yeah, there are many appliance repair videos on Youtube. They're often service guys with a penchant for showmanship. They love what they do and genuinely want to be helpful,

They're not just being helpful; the ones I've seen also include links so that you can buy the replacement part from their online business. It's great salesmanship: "look, you can do it yourself and save a bundle! We'll sell you the parts for a great price!" (even though their price probably isn't really the best, but it's probably fair.)

Repairability varies: it depends on what broke, and how much the parts cost to fix it. I had a first-gen Maytag Neptune washer for about 17 years; it had some problems (including the infamous mold problem they mitigated under warranty), including a failed pump and a belt that slipped off. But finally, the main bearing gave out. The replacement part for this is $400; that just isn't worth it for a machine that old. I can get a newer machine secondhand for less than that, which is exactly what I did.

Also, as we're seeing now with mobile devices, sometimes they're glued together so it's quite impossible to disassemble them without damaging them. iFitIt complained bitterly about this with the new Surface notebook. Luckily, appliances aren't (yet?) built like this.
