Full review
Bosch's Series 8 WNC254ARGB is the washer dryer for a busy household. Bosch UK lists a 10.5 kg washing load and 6 kg in one continuous wash-and-dry cycle, energy class D for the full wash-and-dry label (the washing part alone is class A), 50 litres for an Eco wash and 75 litres for wash and dry, and a 70 dB(A) spin in noise class A. Marks Electrical adds the energy figures: 52 kWh per 100 wash cycles and 305 kWh per 100 wash-and-dry cycles.
i-DOS doses detergent automatically, AutoDry stops drying when clothes are dry, and Wash & Dry 45 washes and dries a small load in 45 minutes. Home Connect gives app control, and AquaStop protects against leaks.
Bosch is offering a five-year warranty on purchases registered between April 2026 and March 2027, plus ten years on the SilentPowerDrive motor. Bosch's own online shop showed it as unavailable when we checked, but Marks Electrical listed it in stock.
Like all washer dryers, drying uses much more energy than washing, which is why the overall class is D. If you have space, a separate washer and heat pump dryer will cost less to run.

Spec check note: Marks Electrical lists noise class D, but Bosch states class A at 70 dB(A); we use Bosch. Marks says Wi-Fi is not applicable while listing Home Connect; Bosch lists Home Connect app control, which we use. Energy per 100 cycles is from Marks, as Bosch's page does not give it.
