The DWHD640JFP sits at the entry-to-mid tier of Thermador’s discontinued J-series generation, with 14 place settings and condensation drying like its 650J/651J siblings, but without the TurboSpeed or Sanitize cycle options offered on the tiers above it — its documented cycle options are limited to Extra Dry, Half Load, and IntensiveZone.
Because it lacks a documented NSF-certified Sanitize option, we don’t assume a Sanitize-cycle complaint applies to this model — the cycle list itself is the first thing checked before diagnosing a missing feature as a problem. Drainage and water-inflow codes are read the same way as on the rest of the lineup.
