I've never been convinced about the idea of serious engineered failure for this type of device. I think there are two problems, both consumer-related; price sensitivity (adjusted for inflation, these machines are far cheaper than they used to be) and demand for features (more modes, smartphone integration, bigger drum, higher spin speed), and something has to give.
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.
