Verdict

The Siemens SN73EX01CE iQ300 is a fully integrated, full-size 60 cm dishwasher featuring a spacious 14 place setting capacity, 6 wash programs, a flexible rack system with a dedicated cutlery drawer, and an efficient Class C energy rating with a 9-liter water consumption per cycle. Its main pros include an exceptionally quiet 40 dB operation, VarioSpeed Plus for up to three times faster washing, intelligent autoOpen Dry functionality, smart Home Connect app integration, a sideLight operation indicator, and a varioHinge sliding door ideal for low plinths. On the downside, it lacks higher-end features like Zeolith drying technology, relies on mid-range condenser drying, and does not include internal cabinet illumination.
