The DWHD661EPR is the panel-ready version of Thermador’s Star Sapphire-spec dishwasher, carrying the same 42 dBA rating, StarDry Zeolite drying, and built-in water softener as the EFM/EFP versions, installed fully integrated behind a customer-supplied cabinet panel.
As the top panel-ready tier in the current lineup, this unit combines the panel-fit checks common to any EPR model with the Zeolite and water-softener maintenance items specific to the 661 spec — we diagnose each as a separate subsystem rather than assuming one problem explains every sign.
