"A dishwasher is a dishwasher, the cheapest model does what the most expensive model does: clean dishes."
A few years ago I replaced my dishwasher as the old one was beyond "economical" repair. Asking friends for recommendations of their proven ones - I discovered that manufacturers change their models every couple of years. On-line reviews were a similar problem - not to mention some of the horror stories.
Finally went for a Siemens as a mid-priced brand used by some friends - and on-line reviews seemed favourable for a specific model.
Every time I use it I wish that I had had the old one repaired. Yes - the new one is quieter and has "eco" features - but it just doesn't clean the dishes reliably. Everything has to be "clean" before it is loaded into the machine otherwise it needs a hand wash afterwards.
I suspect the noise of the old one meant it was spraying the water at a much higher velocity. The "Eco" features also seem to minimise the drying cycle - so that things are still wet at the end.
A microwave oven is an appliance one would expect nowadays to be - well - just a microwave.
I have given up trying to buy a new one. My requirements are obvious - or so I thought: stainless steel cavity; touch timer panel; enough ventilation so that the interior doesn't drip copious amounts of water during cooking. Oh - and no reviews saying "failed after a few weeks" - or - "caught fire".
