The DWHD660EFM is the Masterpiece® Collection, bar-handle version of Thermador’s Sapphire-spec 24-inch dishwasher, matching the DWHD660EFP’s 44 dBA rating and StarDry Zeolite-based drying system but with fixed bar-handle hardware rather than the Professional handle. It also includes the ZoneControl™ customizable lower-rack cleaning zones and Sapphire Glow interior lighting.
Because it uses StarDry with Zeolite, a chamber-heater or fan-motor problem (E2120/E2130) is diagnosed as its own drying subsystem, separate from the drain and inflow electronics that generate the E22-E25 and E14-E18 code families. Sapphire Glow and Blue PowerBeam are status/cosmetic lighting features, diagnosed separately from wash performance.
