I fit kitchens for a living ranging from £5000 – £150,000 so I get to see and install a good spread of appliances, the only ones I would use are –
Miele, expensive but with a service life of 20-30 years so an investment really, the best you can buy.
Siemens, cheaper but still very good
Bosch, cheaper still and still good
Basically avoid anything under £400, they are built down to a price and will not last more than a couple of years at best!
