Not a fan of surface mount components. Not horrible to remove or solder but good luck getting numbers off of them especially if they fail / fry.
If you work on things you can you can figure out the flow and circuitry but still need values or numbers to replace.

Depends on the appliance. A Sub Zero is worth repairing.

Lol. My wife is the same way.

Diverter valve
Is what it was on mine. 18 month old kenmore and started noticing dishes on bottom where not getting clean.

Chapped my ass that such a new appliance would have any failure but none the less I wasn’t about to buy another washer.

Found part for $80 on appliance repair site, cross referenced number to Amazon and picked up part for $25 shipped.

Now the bitch of it it I’m pretty sure the washing machine (clothes) needs a new bearing(s).

The shit they make now is straight garbage but I can’t afford to buy new every 2-3 years. Chaps my ass too that we tried to buy “good” appliances but my cheap-O washer and dryer we bought back in 08’ were the best and held up for 12 years almost.

Buy a Bosch.

Mine is 22 years old and still runs.  Only dishwasher I have ever had, except the wife.

Did you check to see if there was a recall on it?  When our Bosch had an issue, my appliance repair guy checked on the Bosch site, ordered the part and came over an replaced it no charge.

I just spent almost $200 in parts repairing a 20 year old washing machine myself.  No way I was buying one of them new fangled pieces of utter crap.

In five uesrs I have used the dishwasher about 5 times, typically after a large holiday gathering

The things are nearly worthless.

OP's original point is valid though.

Try pricing motorcycle parts. An LED headlight, with about $30 in parts, costs over $1k, and some go to $2k.

It's fucking totally absurd.

Now that they can make things disposable, they must make them fully recyclable.
