The machine leaked the first time I used it. I then had to contact Beko and wait a week for an engineer to come and fix the problem. This is really inexcusable for a brand new item that should be thoroughly tested at the factory.
Now fixed, it's basically fine. Not as thorough cleaning as I would like - sometimes items don't get cleaned property, but this is rare enough. On the plus side, it's quiet and spacious, with a good range of different modes/durations to choose between.
Here's a description of the fault in case this is useful for anyone else: about an hour into the cycle, error 01 appeared on the display, which indicates that water is gathering at the bottom of the machine. Under the machine, there was a noticeable puddle under the left side. It turns out that the seal that connects the water tank to the metal inner body was faulty.
