A Samsung washer that will not drain usually has a clogged drain hose, a blocked pump filter, or a failed drain pump. The washer leaves water in the drum, stops mid-cycle, or shows a drain error code.
This guide covers the checks you can do safely at home and explains when the pump needs replacement. Bonita Appliance Repair has repaired washers in San Diego County since 2012, including Samsung models.
Signs of a drain pump problem
- Water stays in the drum after the cycle ends
- The washer stops at the drain or spin stage
- The washer shows a drain error code. Check your owner’s manual for the meaning of the code.
- The pump hums, rattles, or grinds, or it makes no sound when the washer should drain
- Water drains slowly or backs up
Check these causes first
A clog causes most drain problems, and you can clear a clog without replacing the pump. Before you start, unplug the washer. Water in the drum or hoses will spill, so lay towels around the washer.
- Check the drain hose for kinks or crushing behind the washer.
- Check that the drain hose is not pushed too far into the standpipe. A tight fit can cause slow draining or backflow.
- Open the drain pump filter. Many front-load models have a small access door near the bottom front of the washer. Your manual shows the location for your model.
- Place a shallow pan and towels under the filter, and loosen the filter slowly. Water drains out as you do.
- Remove coins, lint, hair, and other debris from the filter and the opening. Reinstall the filter until it is tight.
- Run a short drain or spin cycle and watch for leaks.
When the drain pump needs replacement
A pump that stays blocked, makes noise, or does not run after you clear the filter may have failed. A pump motor fault, a damaged impeller, or a wire fault can cause the same symptoms. A control board fault can also stop the pump from running. See Samsung washer control board repair.
Why a technician should replace the pump
Replacing the pump means removing panels, disconnecting wiring, and handling a washer that can still hold water. The washer is also heavy, and the parts have sharp edges.
A technician confirms the cause before replacing the pump, so you do not pay for a part that is not broken. The replacement pump must also match your exact model number. See how to find your appliance model number.
