There are auctions where you can buy new display kitchens very, very cheaply. Nobilia kitchens as well as other manufacturers for 2-3000 euros. You just have to be a little patient until something suitable is offered. But when ordering new from the kitchen studio, you pay ten times as much and also wait many months for delivery.
I wouldn’t spend 20 or 30k on a kitchen either.
The heating pump in my Bosch dishwasher fits in pretty much all other dishwashers. So the technology in dishwashers is mostly the same. Regardless of whether it’s a no-name brand or a brand manufacturer. You can just as well buy the cheapest. But since many people here are very brand-conscious, they just want to pay a lot of money for nothing.
If I couldn’t repair it myself – it’s always the same parts that break – I would have already had to buy and install the 3rd dishwasher by now. Within exactly 5 years.
