I repair white goods for a living. Alhough I regularly see 15-20 year old Miele washing machines and tumble dryers, I do, also, see 4-5 year old Miele appliances with blown control boards - a repair bill costing around £650. In my experience, very few appliance engineers touch Miele appliances, which means labour charges are higher and parts prices are eye-watering. As with anything these days, nothing is built like they used to be. As for Bosch appliances, I have noticed that a lot of their newer washing machines/dishwashers are being made in Turkey (incidentally, where Beko have their factories). I own a Beko washing machine, which has been problem-free for 8 years. If I had to buy a washer/dryer, my money would be going on an AEG machine.
