If you compare a low-end washing machine, say a Whirlpool or Inndesit or something, to a mid-range one (Bosch etc), to a high-end one (Miele), it's immediately obvious what's going on. On the low-end one, costs are cut to the bone; everything feels flimsy. The door, the drum, even the buttons feel cheap and flimsy. The mid-range one, things feel better (and repairs become easier; easily replaceable drums etc). The top-end one feels like an industrial machine (and durability improves; high-quality motors, the afore-mentioned iron counterweight and so on).
To a large extent, with washing machines, you get what you pay for (as long as you avoid smartphone integration and other nonsense). There's consumer demand for really, really cheap ones, so manufacturers make them, and they break quickly. You can still buy a top-end one which will last, but it'll cost you.
I paid usd$350 for our new Kenmore washer in 1995. I have had it apart three times in that period, all for repairs that cost less than $50 in parts and at most two hours time.
Contrast this with our 2012 $950 Bosch dishwasher, which broke three times in its second year of service (1-year warranty), and cost collectively $850 to fix because nothing was user serviceable. We threw it out when it broke the fourth time.
My experience with home appliances has been mostly that the cheaper ones last _longer_ than the expensive ones.
So far, only miele does that marketing, but sadly without the price.
[1]Gigabyte did/does that with motherboards, their ultra-durable line, when they tell you all kind of technical stuff(like "we use tantalum capacitors" which attack a common and cheap MB failure point) to convince you it's reliable.
250 euros per ~7.5 years = 33 euros per year.
See the problem ?
But also improving the reliability of washing machines isn't hard or expensive. Remember, you're talking about a machine that the most common source of problem with it is a broken/faulty lid switch. cheap and easy to fix.
Surely, with that level of engineered failure(or maybe extreme cost engineering), there's similar stuff hidden there.
