The DWHD660WFP shares its specs with the Masterpiece-collection DWHD660WFM — 16 place settings, 44 dBA, condensation drying, built-in water softener — but with Thermador’s Professional handle hardware instead of the fixed bar handle. Both were discontinued from Thermador’s current lineup along with the rest of the W-series generation.
Diagnosis follows the same path as its Masterpiece sibling: drainage and water-inflow codes read directly from the documented Thermador error code table, and softener performance checked as its own maintenance item before assuming a deeper wash-system problem.
