Verdict

The Bosch SPV4EMX21E Series 4 is a fully integrated, slimline 45 cm dishwasher featuring a 10 place-setting capacity, a low 45 dB noise level, and a Class D energy efficiency rating that utilizes 9.5 liters of water per Eco cycle. Its main advantages include smart Home Connect Wi-Fi integration, flexible VarioFlex baskets with a third VarioDrawer cutlery rack, a TimeLight floor projection status, and an EfficientDry automatic door-opening mechanism for enhanced drying performance. However, notable drawbacks include its relatively modest Class D energy rating and an eco program duration that takes up to 3 hours and 30 minutes to complete.
