Samsung's table for dishes that do not dry on the DW80B7070 lists five causes: no rinse aid or too little (check the dispenser, use liquid rinse aid and check the rinse aid setting), low water temperature (use a hot supply and rinse aid with Sanitize or SmartDry), too many dishes, concave-bottomed glasses that hold water (empty the lower rack first, then the upper), and Auto Release Dry turned off (turn it on with Lower Rack plus Hi-Temp Wash held for 3 seconds and select A1). Also, multiple detergent tablets used without Sanitize leave dishes wet: select Sanitize or use rinse aid.

Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether Auto Release Dry is on (A1) and SmartDry Hi or Lo was chosen
- The rinse aid level setting and whether the refill light is on
- Whether tablets were used without Sanitize
Try in this order
0 of 5 completedAdd rinse aid and raise the level
ReversibleWhen the Rinse Refill indicator lights, refill with liquid rinse aid. In the settings menu choose F1 to F6, where a higher number dispenses more; the default is F4.
Turn on Auto Release Dry
ReversibleHold Lower Rack plus Hi-Temp Wash for 3 seconds to reach the Auto Release Dry setting and select A1. The door then opens automatically 1 to 15 minutes before the cycle ends.
Use SmartDry
ReversiblePress SmartDry Hi/Lo once for High, which raises the rinse temperature up to 73 C, or twice for Low, which reinforces drying with heated air circulation and is Samsung's recommended option.
Load for drying
ReversibleLoad dishes as recommended and do not clog the hot air outlet at the lower right corner. Keep plastic dishes away from it.
Unload the bottom rack first
ReversibleEmpty the lower rack first, then the upper, so water from concave cups does not drip onto clean dishes.
Model-specific
What is true of this model and not of its siblings
- Drying options in the manual
- SmartDry High increases the rinsing temperature up to 73 C and enhances drying compared with SmartDry Low; SmartDry Low is the manufacturer's recommended option and increases cycle time. Press SmartDry Hi/Lo three times to exit. Disabling Auto Release Dry can affect the drying results, so enable it (A1) for better drying.
