Thermador DWHD770WFP
At 42 dBA the DWHD770WFP is the quieter sibling in the Sapphire family, and its Sanitation option is the feature we get asked about by households with babies or with someone who cooks for large groups. Reaching a sanitizing temperature depends on the heater and a temperature sensor, and both are tested when owners say the dishes are not as hot as they used to be.
Thermador shows this model as no longer available and points to the DWHD760CFP as the model that replaces it. That is useful for us, since the replacement shares the same footprint, 33 7/8 x 24 x 24 inches, and similar parts.
We run a cycle with a thermometer, check the filter and the pump, then open the spray arms. A pump that hums without draining is usually a clog in the drain path, and we clear it before blaming the motor.
We measure the water temperature during a cycle. If the heater or sensor is failing, the temperature will lag. Then we test the parts individually before replacing them.
A clog in the drain hose, the check valve or the impeller is common. Stop the cycle, and we will clear the path and test the pump motor for proper rotation.
The cutout of 33 7/8 x 24 x 24 inches matches, which helps. We can advise, but repairs often cost less than a new unit if parts are available.
