The GFD65 is a spacious, energy-efficient workhorse that does one thing well: dry clothes without fuss, especially if you stick to the mechanical-dial base models that skip the fragile electronics. Step up to touchscreen controls and you inherit a real problem: control boards fail within a few years, leaving the drum spinning nonstop until you unplug the machine, and replacement boards cost $300 when they're available at all. Buy the cheapest dial-equipped version for a decade of boring reliability, or pay extra for features that might total the dryer before it's paid off.
Miele's heat pump dryers once defined longevity, T1 owners routinely saw 15 years of quiet, 120V plug-and-play service, but the warranty collapse from ten years to two tells you everything about where the engineering went. Recent buyers report F47 and F99 error codes within months, and Miele support has turned glacial when owners need help. The three-hour cycle is heat pump physics, not a flaw, but you're paying £1200, 2500 for a machine the manufacturer itself only trusts for 24 months. Hunt down a used T1 if you find one; otherwise, Bosch delivers five-year coverage at half the cost.
