Samsung Washing Machine Won't Drain: How to Fix

The drain error means the machine did not sense the water level dropping in time. That can be as trivial as a sock in the filter or as real as a burned pump winding, so the point of troubleshooting is to spend nothing until the meter tells you the pump is dead.

Kit for the job#

Bring a Phillips #2 screwdriver, a multimeter, a flashlight, towels, and the Samsung Smart Care app on your phone for reading stored codes. No parts are needed for diagnosis; order them only after the test identifies the failure.

Safety#

Disconnect power before testing any internal components. For gas dryers, also shut off gas supply.

Diagnose the drain#

1. Observe and document the symptom. Note whether the tub is full or empty, whether the pump hums or is silent, and exactly what code appears. A humming pump that moves no water points at a jam or a partial clog, while a dead-silent one during the drain step points at a power or winding problem — write down which you have before you touch anything, because the two lead down different paths.
2. Check the simple causes first. Lay the towels, open the front debris filter, and expect a cupful of water to spill; clear coins, lint, hair, and the occasional sock. Then pull the drain hose and check its whole run — a kink behind a foot, a crush against the cabinet, or a clog where it enters the standpipe will all stall the drain. Reseat the hose no higher than the machine's spec so it cannot siphon. The large majority of 5E calls end right at this step.
3. Test components systematically. With power off, remove the pump access and inspect the impeller for a wrapped thread or a shard jamming the vanes, spinning it by hand to feel for grit. Then set the meter to resistance and read across the pump motor terminals — an open or shorted winding condemns the DC31-00054A pump, while an in-range reading tells you the motor is healthy and the fault lies elsewhere.
4. Identify the failed component. If the filter and hose are clear and the pump reads open, the pump is your part. If the pump reads healthy but never energizes on a drain, watch for 120V or 240V arriving at the pump connector during the drain step: no voltage there means the harness or the control board is driving the failure, not the pump itself.
5. Verify before ordering parts. Re-run a short cycle with your findings in mind and confirm one clear fault. Ordering a pump on a hunch when a clogged filter was the real problem is the most common money-wasting mistake on this repair, so prove the diagnosis before you buy anything.

When to call a pro#

If the pump and drain path are clear yet the machine still will not drain, the water-level sensor or main board may be misreading, which is a technician-level trace. Repeated pump failures point at a chronic problem — a partial clog shredding impellers or a leak drowning the pump — worth a professional eye.
