Very logical design with a retro touch to the power supply. Probably to avoid using a switchmode type in a product involving liquid.

Pretty much what I expected inside, bar the standard transformer, I was expecting to see capacitive dropper or maybe a SMPS. As Wim said, the Nespresso ones (well one at both current and old work anyhow) have magnetic coupling, but all the others (Aldi & another brand) I have ever seen use the silicone seal like this one which seems a recipe for disaster.
