...because that is often their experience.
However, what people seem to forget, it isn't that it is made in China or anywhere else that has a pool or cheap labour, what is important is the specifications that the product is built to. Any manufacturer can technically build a top quality or poor quality product - it isn't dependant of where it is made, just what actually goes in.
If Miele were to use a motor in their washers that was 'good for 500 cycles', then imagine how long that machine would last and what it would do to their reputation. So Miele specify good quality motors (and other parts) to ensure the quality is built in.Miele also make very distinct models which HAVE KEY DIFFERENCES mechanically the further up the range you go. This differentiates the models.
As an example, and using motors, Miele use a different motor on their top models which is incredibly quiet. Electrolux, to achieve a better sound profile, supply an insert for the base of the machine to try and achieve a difference between one model and the next. Same motor, same chassis, same basic machine....plus one insert to reduce noise - cost, probably about 50p.....but you won't be paying that...more like GBP40.00
In many ways, we have brought the demise of quality on ourselves. Consumers seem to have lost the focus of quality/price by associating 'quality' with 'gadgets' rather than build and longevity. Manufacturers have adapted to this miss-match, particularly with the availability of reliable and inexpensive electronics.
As an example. Electrolux import a range of front-load washers into Australia. Most are Zanussi based machines made in Thailand. Top range ones still come from Europe. They sell these across a couple of brands - Simpson for budget and Electrolux for mid-line and premium.... The Simpsons do look more basic. No digital display, less program options, generally lower spin speeds and smaller capacities.
However, the motors, basic electronics (and main programs!), chassis/suspensions are the same. There is nearly a 20% difference in price between the top 7kg/1000rpm Simpson without display and the same basic machine sold as a bottom line model in the Electrolux range.
When Electrolux was ditching the washing machine side of the Westinghouse brand here, I bought one. Same basic machine that was badged as John Lewis in the UK for AUD $570. The equivalent Electrolux was nearly $900.....
Bit of a ramble, but I hope it makes sense.....manufacturers distinguish by 'the frills' more often than not these days...with some exceptions AND where it is made does not always point to good or bad quality.
