  • 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.

Bottom Line

Bottomline inforgraphicsBosch 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.

Wash programs of the Bosch Serie 4 7KG front loading washing machine WAK2426SIN

Wash programs of the front-loading washing machine

The following are the various wash programs of this Bosch washing machine. Remember, choose a washing machine that offers many options. Look for ones that give you control over tub spin speed and spin cycle, rinse options, pre-wash and turbo wash modes for handling stubborn stains, fault code display, washer dryer combo, etc.

  • Cottons & Cottons 60 – This wash program is suitable for handling colored cotton garments. In this mode, the washer increases the water temperature up to 60C to remove tough stains. Cotton 60 is the economy cotton mode that completes in 60 mins. The washer uses a 1200RPM spin speed to wash clothes in this mode.
  • Wool & Delicates/Silk – This wash program of the WAK2426SIN is suitable for washing causals and delicates. You can use the Wool wash mode for garments meant for hand wash in the label. The Delicates wash program will give you a gentle wash and remove solid and protein stains from a baby’s clothes by providing better rinse performance.
  • Jeans & Sports – Use these modes for clothes that have heavy soil. This mode can take various types of laundry (except delicates like silk and wool). The Jeans wash mode is for heavy and rugged garments.
  • Synthetics – The Synthetic wash cycle is for washing synthetic material.
  • Quick 15/30 – This wash program takes only 15/30 minutes and is suitable for washing lightly soiled laundry.
  • Rinse – Use this wash mode for laundry that needs only rinsing. For best results, add fabric softener to the laundry.

Other features of the Bosch Serie 4 7KG front load washer WAK2426SIN

Other features of the front-loading washing machine

In addition to the wash programs, this Bosch washing machine also comes with the following useful features.

  • Delay start function – Use the start delay function to set the expected start of the washing cycle. You can set a start delay from 1 hour to 24 hours.
  • Childproof lock – For added safety, this washer comes with a Childproof lock feature. You can activate the key lock by pressing the Delay start and Spin Speed buttons for 3 seconds. When the child lock is on, all the control panel functions become inaccessible.
  • ActiveWater – The Bosch WAK2426SIN washer has a special spin cycle to reduce water wastage. Using its sensor, this washer cuts off water intake if it senses only a half-load.
  • Spin speed selection – This washer spins its drum with a top spin speed of 1200 RPM. Each wash program has a pre-defined spin speed. You can use the Spin button to change the spin speed in any wash program.
  • Water Temperature selection – Depending on the wash program, you can select the desired water temperature for washing clothes. This washer uses an inbuilt heater to raise the water temperature for washing your laundry. You can select the water temperature up to 95 C.

  • Anti-tangle – Press the anti-tangle button to reduce the tangling of your clothes. At feel that this is not a practical feature considering this machine is not a 100% dryer. You will anyway hang your clothes to dry.
  • Water plus – Press the water plus button to increase the water intake inside the tub. This option is useful when you want to remove detergent altogether from your laundry.
  • SpeedPerfect – Press the SpeedPerfect button to minimize the wash time. In this mode, the washer increases the spin speed to reduce the wash time. Watch out; this mode will consume more power.
  • EcoPerfect – EcoPerfect ensures low power consumption and, at the same time, delivers excellent washing performance. This is yet another feature that isn’t practical.
