How to Unclog a Samsung Washing Machine
A Samsung washer that will not drain and throws 5E almost always has a clogged debris filter, a jammed drain-pump impeller (DC31-00054A), or a blocked drain hose. Clearing all three is a beginner job of about 20 to 40 minutes; expect standing water.
Three places a clog hides#
Samsung's front-load drain path has two stages plus the hose: the debris filter catches large items, the pump impeller pushes the water, and the drain hose carries it to your standpipe. When the filter overloads or small debris slips past, the impeller jams, and a pump forced to run against a blockage can burn out. Work all three points in order.
Before you start#
| Category | What you need |
|---|---|
| Tools | Phillips #2 screwdriver, a shallow pan, towels, flashlight, pliers, a flexible brush |
| Parts | None, unless the pump (DC31-00054A) is damaged |
| Time and level | 20 to 40 minutes, Beginner |
Safety warning: Unplug the washing machine before beginning. Water will drain when you open the filter — protect your floor.

Step-by-step#
1 - Set up for water. Unplug the washer; the drum is probably holding water. Open the small access door on the lower-left front and slide a shallow pan (a cookie sheet works) beneath it, with towels around it, since the sump and hose can hold a few cups.
2 - Drain it down slowly. If your model has the small black emergency drain tube beside the filter cap, pull it out, uncap it, and let water run into the pan. Otherwise, twist the main filter cap counterclockwise just a quarter turn and hold it there so water flows in a controlled stream; close it to empty the pan and repeat until the flow stops.
3 - Remove and clean the filter. With the flow stopped, unscrew the cap fully and pull the filter out. Coins, hair ties, bobby pins, lint balls, and small socks are the usual finds. Clear the housing, then scrub the filter mesh under running water with a toothbrush.
4 - Free the impeller. Shine a light into the housing cavity to find the multi-blade pump impeller at the back. Spin it with a finger; it should turn freely both ways. If it is jammed, tease out the hair, thread, or rubber bands wound around the shaft with pliers until it spins clean. A broken impeller, or a motor that will not turn with the impeller clear, means the pump (DC31-00054A) has failed.
5 - Check the drain hose. Disconnect the hose at the standpipe, hold the end over a bucket, and blow gently; air should pass with little resistance. Clear any lint or hardened-detergent blockage with a flexible brush or a garden hose, and straighten any kink, since a pinched hose alone can trigger 5E.
6 - Verify the standpipe. The hose should sit about 6 to 8 inches into the standpipe with an air gap around it, never sealed or taped, so it cannot siphon the drum during fill. Correct it if it has been pushed in too far or sealed.
7 - Reassemble and test. Refit the filter cap clockwise until snug, letting its O-ring seal without overtightening, reconnect the hose, and close the door. Plug in and run a Rinse and Spin, watching the filter area for leaks and listening for a steady pump hum as the drum empties with no 5E.
Troubleshooting a persistent 5E#
- Impeller spins but drain is weak: the pump motor may stall under load. Feel the pump housing during a drain cycle; excess heat means a struggling motor.
- Hose rises too high: most Samsung models cap drain height around 36 inches, above which the pump cannot push water.
- No pump vibration at all: suspect a broken wire or a board relay rather than a clog.
- Slow drain with the pump running: the one-way check valve at the hose connection may be stuck. Pull the hose at the pump outlet and inspect the flap.
