I would have to say that my experience of brands doesn't necessarily follow the general trends that are talked about on here. I really think it's difficult to generalise about the huge manufacturers like Indesit, Candy, BSH and Electrolux.
I've seen fantastic products from all of them at the high end of their ranges and utter rubbish at the lower price points.
The likes of Miele can cherry pick and simply doesn't do lower end. Also, many of the machines from the old days were designed for a very different market and were MUCH more expensive (in relative terms) than a bottom of the line modern machine.
If you for example compare the lowest end basic Indesit model with the 1600 spin Aqualtis you'll find they're totally different machines. One is practically disposable and cheaply built, the other is a decent washing machine.
Likewise, a cheap Candy machine vs a Hoover Vision or Candy Grando will give you a similar shockingly huge difference.
It's all about branding, which is why you're seeing all of the major machine makers tier their brands. e.g. Indesit vs Hotpoint/Ariston and Scholtes
or Candy vs Hoover
Electrolux : AEG, Electrolux, Zanussi and then budget brands like Tricity Bendix..
IF the same badge is applied to the cheap stuff as the high quality stuff you end up with a tarnished name.
In my own experience I've had Ariston dishwashers that lasted almost 20 years without a single service, and Bosch machines that have been ridiculously prone to problems e.g. our dishwasher needed 2 control panel replacements and two new detergent cups!!! We also had a Zanussi (Electrolux) Jet System washer that went through two wash recirculating pumps in 4 years!!
The only brand that's held true in terms of reliability has been Miele.
I really think you need to be looking at buying middle/upper range products rather than avoiding particular brands.
