The SMEG DI4522 has a rated capacity of 9 place settings (ps), making it a compact 45 cm fully-integrated dishwasher suitable for smaller loads.

This model provides 6 programmes: Soak, Express 50°, ECO, Self clean, Mix 60° and Auto 50°–60°. The Auto programme recognises the type of dirt and automatically adjusts the washing parameters, while the ECO programme is designed to use a low amount of water and energy.

Based on the ECO programme, the energy consumption is 70 kWh per 100 cycles and water consumption is 9.9 litres per cycle. The ECO programme is described as an economic wash that uses a low amount of water and energy to provide an environmentally friendly cleaning option.

The dishwasher uses a natural condenser drying system with Dry Assist+. At the end of the cycle, an automatic door opening system helps to improve the drying process. Some models also feature special anti-drip nozzles that further enhance drying performance.

Total Acquastop includes an electronic device on the water intake hose that monitors water levels in the machine, detects leaks in the hose and switches off the water supply immediately when necessary. This is in addition to the partial Acquastop protection present in all Smeg dishwashers.

Yes. The DI4522 includes a delay timer option of 3 hours on the appliance, and the delay timer feature is described as being able to postpone the start of the programme by up to 24 hours, allowing flexible scheduling of wash cycles.
