The DWHD661EFP is Thermador’s Star Sapphire® tier 24-inch dishwasher, part of the Radiance Collection, with Home Connect app connectivity on top of the same core wash and drying systems used across Thermador’s dishwasher lineup. Because Thermador documents an unusually detailed error code list for this category, we start diagnosis from the exact code displayed — checking the filter and drain pump for drainage codes, the inlet hose for water-flow codes, and treating any E15/base-water code as a reason to shut off the water supply immediately, exactly as Thermador’s own documentation instructs.
The Home Connect app can also surface some diagnostic information before a technician visit, which is worth checking and mentioning when booking.
