A pool of water above the filter after a completed cycle needs investigation, but a little water in the sump can be normal on some models. Check the manual before treating every visible drop as a drainage failure.
Read the code correctly
5C / 5E concerns drainage on applicable Samsung models. OC / OE relates to an over-level condition, while LC / LE indicates a leak-detection condition on applicable models. Use the exact model’s code list; these are not interchangeable diagnoses.
If there is a leak warning or water outside the appliance, stop using it and close its water tap if safely accessible. Do not keep resetting it, tilt it or bypass the sensor.
Owner checks for a drainage problem
Switch off and safely isolate power, let the water cool and wear gloves because broken glass may be hidden. Remove and rinse only filters the manual allows you to remove. Do not reach blindly into the sump or remove an unfamiliar pump cover.
Inspect accessible drain-hose sections for kinks without pulling out the integrated machine. Check whether the kitchen sink also drains slowly. A shared plumbing blockage may need a plumber; recent installation work can also affect the drain connection. Do not dismantle a waste-disposal unit or disconnect plumbing unless qualified.
If the problem remains
A pump, sensor, wiring or installation fault may require testing. A humming noise alone does not confirm pump failure. Send the displayed code, model and when the water remains when requesting Samsung dishwasher repair. Ask for a diagnosis before authorising replacement parts.
