The DWHD640JFM matches the Professional-handle DWHD640JFP’s spec — 14 place settings, 44 dBA, condensation drying, built-in softener, no TurboSpeed/Sanitize — with Masterpiece Collection bar-handle hardware instead.
Diagnosis follows the same approach: drainage and water-inflow codes are read directly from the documented Thermador error code table, and softener performance is checked as a maintenance item, since both models in this pairing share identical wash, drain, and control electronics under different handle hardware.
