The DWHD660WFM is a discontinued 24-inch dishwasher from Thermador’s previous W-series generation, sitting at the mid-tier of that lineup with a built-in water softener and condensation drying, but without the Zeolite-based StarDry system Thermador introduced on higher tiers and later generations.
Because there’s no Zeolite drying chamber on this model, persistent wet-dish complaints are diagnosed against the standard heat-pump/condensation drying path and softener performance rather than a Zeolite-specific error code. Drainage and inflow codes are read the same way as on current-generation models, since the core control platform carried forward.
