I don't think the reliability of (front load) washing machines sold here in the UK has changed much over the years, I don't think it has ever been more than about 10 years on average. If you want one that's likely to last a fair bit longer, you'd expect to pay a lot more money for a premium machine like a Meile.
I'd normally expect the rubber seal around the shaft to start leaking after about 8 - 10 years, letting water get to the bearings and wash out the grease. Which is usually terminal since most people will be reluctant to fork out for the high cost of repair on a machine that is already 10 years old, or want to put up with the inconvenience of waiting at home for a repairman to show. Before machines had effective out of balance detection, people would keep on using them till the rumbling and vibration got too much to bear, or something broke.
My mum used to have a repairman out quite often fixing her first couple of machines. Mostly trivial faults such as the fill valves not working, thermostat, and most commonly the water level pressure sensor, or its air chamber or pipe blocked. I'd usually only find out the machine had gone wrong after it had been fixed when I'd get home from school and see the old part that had been left behind on top of it. I used to take them apart as I was curious how the worked and would clean them up to get them working again and keep one as a spare. Never got to use any, not even after I started repairing more significant faults, because she'd never let me know it was broken.
Unlike the guy in the rant, while it used to be a problem, I've not had a solenoid valve on ours fail with a blocked pinhole or for any other reason for getting on for nearly 40 years now.
