Miele's appeal is durability: the company says its machines are tested for the equivalent of 20 years of use, and Miele consistently tops UK reliability rankings and independent repair data. The WSD323 adds PowerWash and a QuickPowerWash cycle Miele rates at around 49 minutes for a full clean, plus the patented honeycomb drum designed to be gentle on fabrics. The trade-off versus the Bosch above is stark on price and capacity: you pay roughly double for an 8kg drum rather than 9kg, so you're buying claimed lifespan and fabric care rather than headline specs or value. If you keep appliances for a decade or more and hate replacing things, the maths can work; if you upgrade every few years it's hard to justify over the Bosch. Indicative pricing is around £999-£1,099; check the retailer, as stock is thinning at some sellers (checked September 2026).
