Quick answer
F3 on a DCS DD24 DishDrawer means the temperature sensor failed; check that incoming water is under 150°F.
Model compatibility: DCS reuses codes across series and model years, so F3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Temperature sensor failed.
A DD24 DishDrawer that displays F3 is reporting a failed temperature sensor.
Check the supply water
The user guide asks you to confirm that the incoming water is under 150°F. A tempering valve may be needed on the supply if it is hotter.
Codes to compare
Heating and sensing faults share the F-series: F4 covers a faulty temperature sensor or element, while F2 is a motor problem and F1 a flood switch event.
