Samsung Dishwasher Drain Issues: Standing Water and Slow Drain

Quick Answer

Standing water after a Samsung cycle can appear with or without an error code. The Samsung drain pump has a mesh cover that collects fine debris not caught by the main filter.

Samsung dishwasher drain problems trace to three locations in order of likelihood: the filter basket, the drain pump mesh cover (Samsung-specific clog point), and the drain hose. Samsung's pump mesh requires a small brush to clean and is different from the main filter — this is the most commonly missed step. If the drain pump is silent during the drain phase, it has failed and needs replacement (DD31-00005A).

What Does the DRAIN-ISSUES Code Mean?

Standing water after a Samsung cycle can appear with or without an error code. The Samsung drain pump has a mesh cover that collects fine debris not caught by the main filter. Clean both before checking the hose or testing the pump motor. Most drain issues are resolved by cleaning.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Drain pump mesh cover clogged with film or debris40%

Filter basket blocked with food accumulation24%

Drain hose kinked, clamped, or too low14%

Pump motor failure12%

Drain pump impeller jammed by foreign object10%

Symptoms You May Notice

Puddle of standing water in tub bottom after cycle
SC, 5C, or SE error code displayed
Dishes not rinsing cleanly — old water residue
Drain pump hum is very quiet or absent during drain phase

Can you reset a Samsung dishwasher to clear the DRAIN-ISSUES code?

If SC/5C/SE code is showing, hold Start/Cancel for 3 seconds to clear after resolving the drain blockage.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Open the door and check the water level

Open the door and check the water level. If water is above the filter, bail or absorb enough to access the filter assembly.

Pull and twist the filter cylinder out of the tub floor

Check the drain hose routing at the back of the machine

Run a cycle and listen specifically during the drain phases

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Is it normal for a little water to remain in a Samsung dishwasher?

A small amount of water (less than a cup) in the very bottom of the tub or inside the sump cavity is normal — it keeps the door seal moist. A visible puddle covering the tub floor is not normal and indicates a drain problem.

Why does my Samsung dishwasher drain slowly but eventually clear?

Slow drainage usually means the pump mesh is partially clogged. The pump can move some water but not at full capacity. Clean the pump mesh with a small brush inside the sump opening to restore full drain speed.

How is the Samsung drain pump mesh different from the filter?

The filter basket (cylindrical, pull-and-twist) catches large food debris. The pump mesh cover is a flat screen at the bottom of the sump opening, visible only with the filter removed. It catches fine particles that pass through the filter and requires a brush to clean, not just rinsing.
