Where to buy the Smeg DI4522 dishwasher
🏆 Review & price summary
The Smeg DI4522 dishwasher is a practical 45cm fully integrated model with nine place settings, six programmes, automatic door opening, adjustable baskets and Total Acquastop protection. It is well suited to compact kitchens, although the E energy class, four-hour Eco cycle and limited slimline capacity are important trade-offs.
✓ Key strengths
- ✓ Fully integrated 45cm format suits compact kitchen layouts
- ✓ Dry Assist+ and automatic door opening support better drying after the cycle
- ✓ Flexifit sliding hinges and adjustable feet offer useful installation flexibility
- ✓ Six programmes include Auto, Eco, Self Clean and Express options
- ✓ Stainless-steel tub, stainless-steel filter and Total Acquastop provide reassuring construction and water protection
Worth considering
- E energy class is below the higher-rated dishwasher options available in the category
- Nine place settings provide less capacity than a full-size 60cm dishwasher
- The 46dB noise rating is quiet but not class-leading for open-plan kitchens
- The four-hour Eco programme is slow when a faster turnaround is needed

The review counts only features explicitly assigned to the exact model in Smeg's product specification; additional retailer claims not clearly assigned by the manufacturer have been excluded.
Slimline integrated design
The Smeg DI4522 dishwasher is designed for fully integrated installation in a 45cm-wide cabinet, making it suitable where a full-size dishwasher will not fit. Its 818mm height, adjustable feet and Flexifit sliding hinges give useful installation flexibility, while the kitchen furniture panel is fitted separately.
The sliding hinge system is particularly useful for kitchens with a low plinth because the furniture panel moves over the dishwasher door rather than opening directly into the plinth area. The manufacturer specifies compatibility with a 2–7.5kg frontal panel.
Programmes and cleaning performance
There are six programmes: Soak, Express 50°, Eco, Self Clean, Mix 60° and Auto 50–60°. The Auto programme is intended for mixed loads and adjusts the washing parameters, while the Extreme option can increase the selected programme's temperature and duration for more demanding loads.
The dishwasher has electronic controls, a programme-time display, salt and rinse-aid indicators, a three-hour delay option and automatic switch-off. This is a useful, practical feature set, although it is not as extensive as models offering a wider range of specialist cycles.
Loading and drying
The nine-place-setting capacity is appropriate for a slimline dishwasher, with a height-adjustable upper basket and a separate cutlery basket. The upper basket can be adjusted through two levels, and the manufacturer lists maximum dish heights of 20cm in the upper basket and 31.5cm in the lower basket.
Dry Assist+ combines natural condenser drying with automatic door opening at the end of the cycle. The lower basket also has anti-drip inserts, while the stainless-steel tub and filter should provide a durable interior.
Efficiency, noise and overall verdict
The dishwasher has an E energy rating, using 70kWh per 100 Eco cycles and 9.9 litres of water per cycle. Its four-hour Eco programme is economical in operation but lengthy, so the Express programme is more appropriate when turnaround time matters.
At 46dB, it should be reasonably unobtrusive in normal kitchen use, although quieter alternatives are available. Overall, the Smeg DI4522 dishwasher is a well-specified slimline integrated model with strong installation flexibility, useful drying features and sensible safety protection, but its E rating and nine-place capacity limit its appeal for buyers wanting maximum efficiency or full-size loading space.
