Turn off the Samsung dishwasher and unplug it from power before inspecting 🔧. Remove the bottom rack and take out the filter to clean away trapped food or grease. Check the drain hose at the back for clogs, kinks, or bends blocking water flow. Inspect the drain pump for debris and clear out any objects preventing it from running. If the Samsung dishwasher still won’t drain, the pump or control board may need replacement for a permanent fix.
