Pros
- The WAK2426SIN 7KG front loading washing machine comes with a silent EcoSilence drive, SpeedPerfect, ActiveWater, and bacterial reduction tech.
- The WAK2426SIN’s Auto Restart option ensures that this washing machine restarts from where it stopped during power cuts.
- The Bosch WAK2426SIN washing machine has a 7KG load capacity, sufficient for a medium-sized family.
- It comes with 15 automatic wash programs and three additional options that can handle any laundry type.
- The new anti-tangle feature minimizes tangles in clothes up to 50%.
Cons
- Bosch’s after-sales & service is patchy. In some cities, the service quality is excellent, and in others, it is downright poor.
- Expensive and with far fewer features compared with Whirlpool’s 7212. We understand German engineering etc., but Bosch should drop their price considering their service quality.
- There are no Steam and WiFi options. The WAK2426SIN lacks features that you see in other 7KG front loading washing machines.
- This machine is not a washer dryer and will not dry your clothes 100%.
Bottom Line
Bosch stands for quality and innovation. Expect no less from the WAK2426SIN. It is a durable machine with exceptional build quality. This washing machine should work without issues for many years to come. With a 7KG wash capacity, EcoSilence drive, one of the best inverter motor, this Bosch washing machine makes washing clothes easy.
Watch out! This Bosch washer will not give you the best value for money. It lacks some of the features you get in lower-priced 7KG Whirlpool washers. Also, the after-sales service for a premium brand like Bosch is poor and unacceptable. Also, its features like anti-tangle and SpeedPerfect are not practical or useful.
Without features like Steam and WiFi connectivity, the Bosch WAK2426SIN disappoints. We urge our readers to carefully evaluate all their options and read our reviews of other washing machine brands before choosing this washer.
