Thermador dishwasher not draining is a known issue affecting DWHD660WFP. Our technicians specialize in Thermador-specific diagnostics and repair.
Bosch dishwasher was leaking onto our hardwood floors in Rockridge. EasyBear sent someone same-day who replaced the door gasket and checked the drain pump — completely fixed and no water damage.
“One of the induction zones on our Thermador cooktop stopped responding. The EasyBear tech diagnosed a failed induction coil and ordered the part. Second visit was quick — total cost $385. Not cheap,…”
Thermador dishwasher not draining is typically caused by clogged drain hose or failed drain pump. Thermador-specific factor: star speed wash cycle drain pump thermal fuse tripping during accelerated programs with heavy soil loads. Repair costs $100-$250 with free diagnostic and 90-day warranty.

Sapphire series zeolite crystal drying system regeneration failure causing excessive moisture retention and sensor recalibration loops
AquaStop Plus anti-flood system false activation from condensation on the base pan moisture sensor, halting drainage mid-cycle
Third rack Flex loading tray rail binding preventing complete drainage of trapped water in the tray recess
InfoLight floor-projection LED failure on fully integrated panel-ready models — the only visible cycle status indicator, absence masks drain errors
Other Thermador models may also be affected. Book a free diagnostic for confirmation.
Seeing one of these codes? It likely indicates not draining.
Sacramento Thermador zeolite drying system degradation accelerates with hard water — mineral deposits on the zeolite granules reduce their moisture absorption capacity, and the regeneration cycle cannot fully restore performance. After 800-1000 cycles, the zeolite cassette requires replacement. The dry Sacramento climate masks the symptom initially because ambient evaporation compensates for reduced zeolite performance.
Tilt the unit forward 45 degrees and check the base pan for water — any water triggers the AquaStop E15 sensor and blocks drainage
Run a drain-only test cycle via the Thermador service menu — listen for drain pump engagement and time the drain duration
Inspect the drain hose at the garbage disposal connection — verify the disposal knockout plug was removed and the hose has a proper high loop
Check the InfoLight projector on integrated models — if the LED is burned out, the user may not see the error code displayed; access the service menu for stored fault codes instead
The technician first checks the AquaStop base pan for condensation or leak water, dries it, and resets the sensor. For genuine drain pump failure, the pump assembly is accessed from below and replaced — a 45-minute repair. Zeolite cassette replacement is a Thermador-specific procedure requiring removal of the drying module from the door assembly and installing the factory-charged cassette. The InfoLight LED is replaced as a complete module through the bottom panel.
