The DWHD640EFP is Thermador’s Emerald® tier 24-inch dishwasher, sharing the same core wash and drain systems as the Sapphire and Star Sapphire tiers above it in the Radiance Collection. A door-sensor problem (E8000) on this or any Radiance Collection model typically means the unit won’t start reliably, since the door sensor is part of the safety interlock the control system checks before running a cycle — not something to bypass, but a reasonably quick diagnostic once confirmed.
As with the rest of the lineup, we read the exact displayed code against Thermador’s own documented meaning before assuming which system is actually to blame.
