Smeg sells you the retro-chic kitchen dream, but the appliance underneath is a gamble wrapped in gorgeous sheet metal. Heating elements have a documented habit of dying every few years, and replacements cost enough to make you wince twice, once at the bill and once at the realization you're locked into premium-priced maintenance for life. Cleaning is fine, not great, and you're paying a steep markup over Bosch or Miele for looks alone. Buy this if the aesthetic is worth the repair lottery and you've budgeted for parts; otherwise, get something boring that actually lasts.
Thermador builds a genuinely excellent dishwasher: lab-best cleaning, library-quiet operation, and the kind of rack flexibility that makes loading feel like a small daily win. The problem is what happens when the $2,000+ machine breaks. Owners who've needed service report waits stretching past two months, repair bills hitting $400 on three-year-old units, and parts shortages that leave expensive kitchens stuck with a dead appliance. Unless you're comfortable self-insuring a luxury purchase with spotty service infrastructure, spend half as much on a Bosch 800 Series and bank the difference for your next remodel.
