Samsung washer: the short answer
On a Samsung washer, water left in the drum at the end of a cycle most often comes back to drain hose kinked, crushed or pushed too far into the standpipe, with pressure switch or level sensor reading water that is not there the next thing to rule out. Samsung is unusually sensitive to being out of level and to a restricted supply or drain, so installation faults belong near the top rather than at the bottom. The first checks below are owner-safe and need no tools beyond a flashlight; if they come back clean, what is left sits behind a panel and belongs to a technician.
What you are actually seeing
- Water standing in the drum when the cycle ends
- The machine humming at the drain stage with the level unchanged
- Not this fault: Water on the floor rather than in the drum — Means: a leak, which follows a different ranking
Ranked for Samsung, most likely first
- Drain hose kinked, crushed or pushed too far into the standpipe — Why: The hose is squeezed against the wall when the machine is pushed back, and a hose inserted too deep siphons and airlocks. — Owner serviceable: true — Brand note: Samsung is unusually sensitive to being out of level and to a restricted supply or drain, so installation faults belong near the top rather than at the bottom.
- Pressure switch or level sensor reading water that is not there — Why: A machine that believes it still holds water will not spin, and a blocked pressure hose is a common and quiet cause of that. — Owner serviceable: false
- House drain or standpipe partially blocked — Why: A washer discharges faster than a kitchen sink, so a partly blocked standpipe backs up under the washer and nowhere else. — Owner serviceable: true
- Drain pump filter blocked with lint, coins or hair — Why: On any front loader the pump filter is the first restriction and the first thing to check; it is also the only part of the drain path an owner can reach without tools. — Owner serviceable: true
- Body: The order below is specific to how Samsung builds this appliance; on another platform the same list ranks differently.
What to check, in this order, and why
- Samsung shows a self-diagnostic code on the panel and holds it in memory; note the code before cutting power, because power-cycling clears it. — Why: This one comes first because of how Samsung builds the machine, not because of where the fault ranks.
- Pull the machine forward and follow the drain hose for kinks and insertion depth. — Why: Installation faults are visible and free to correct.
- Note whether the machine drains but refuses to spin. — Why: That pattern points at the level sensing rather than the pump.
The checks you can safely do yourself
- Free and reset the drain hose — Tools: A flashlight — Time: About twenty minutes — Body: Pull the machine forward and follow the drain hose.
- Test the house drain — Tools: A bucket — Time: About ten minutes — Body: With the washer hose out of the standpipe, pour a bucket of water in steadily.
- Body: Stop at the first step that would need a meter on live terminals.
Before you open anything
Safety
Never defeat a door interlock, a lid switch or a safety thermostat to keep an appliance running. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Water and electricity share this cabinet. Switch the breaker off before mopping behind or under the machine, and never run an appliance that is standing in water.
Where the owner line ends
Call a technician in any of these situations. the filter, the pump, the hose and the standpipe are all clear and the drum still holds water

This is generalized information for Samsung washers as a family. It does not carry the model-specific detail — code tables, part numbers tied to a serial range, a chassis-specific procedure — and it defers to any page written for your exact model. Where a configuration changes the ranking materially — top-load models — that has its own page, and it carries the detail this one leaves out.
