Symptoms

Look for these signs to confirm error 5C on your Samsung Dishwasher:

  • 5C error code displayed – often at the end of a wash cycle during drain phase
  • Standing water visible at the bottom of the dishwasher tub
  • Humming sound from the drain pump with no water movement
  • Dirty water backs up into the tub from the sink connection
  • Error may follow a period of gradually worsening drain performance

DIY Fix (Safe)

  1. 1Remove the bottom rack and pull out the drain filter assembly – clean all parts thoroughly under running water
  2. 2Check the sump area below the filter for any large debris like broken glass, toothpicks, or food
  3. 3If connected to a garbage disposal, ensure the knockout plug inside the disposal inlet was removed during installation
  4. 4Check the drain hose under the sink for kinks – it should rise to a high loop before connecting to the drain
  5. 5Run the garbage disposal to clear any blockage at the shared drain connection

Professional Action Required

  1. 1Access and inspect the drain pump for a jammed impeller – remove any debris lodged inside
  2. 2Test the drain pump motor for continuity – replace if windings are open or shorted
  3. 3Inspect the drain check valve (flapper) for stuck position or debris preventing operation
  4. 4Check the control board drain pump relay for proper operation
  5. 5If drain performance has been worsening over time, the entire drain pump assembly may need replacement due to worn impeller blades
