Samsung DMT400RHB Quick Start Guide

To reset your Samsung DMT400RHB dishwasher, press and hold the start button for 3 seconds. This should reset the appliance and clear any error codes.
Check the drain hose for kinks or blockages, and ensure that the filter is clean. If the problem persists, inspect the drain pump for any obstructions.
To clean the filter, remove the lower rack and locate the filter at the bottom of the dishwasher. Twist it counterclockwise to remove it, then rinse it under running water to remove debris.
Ensure you are using a rinse aid, as this helps prevent spots. Also, check the water temperature; it should be at least 120°F (49°C) for optimal cleaning.
Unusual noises may be caused by items touching the spray arms or loose objects in the dishwasher. Ensure everything is properly loaded and that no items obstruct the spray arms.
Clean the spray arms every few months to ensure optimal performance. Remove them and rinse under water, using a toothpick to clear any clogged holes.
The 'Heavy' cycle is designed for heavily soiled pots, pans, and dishes. It uses more water and higher temperatures for intensive cleaning.
Ensure that the rinse aid dispenser is filled, and choose a cycle with a heated dry option. Also, slightly open the door after the cycle ends to allow steam to escape.
Check if the spray arms are spinning freely and that nozzles are not clogged. Make sure the dishwasher is not overloaded and that dishes are properly arranged.
Run an empty cycle with a cup of vinegar on the top rack monthly to eliminate mold and mildew. Keep the door slightly open between cycles to allow the interior to dry out.
