Quick answer: Water entering a powered-off washer is not normal. Close both household supply valves, stop using the machine, and determine whether the water is clean supply water entering through the inlets or dirty water backing up through the drain.
This symptom can occur on different washer styles, but the internal valve arrangement and service procedure vary. The checks here remain outside the cabinet and do not assign a failed part without model-specific diagnosis.
What the documented behavior tells you
- Samsung instructs owners to turn off the water valves when a washer continuously fills, because the level can rise without the normal cycle protection.
- Clear fresh water appearing slowly after shutdown points toward the supply side, while discolored or odorous water after household draining suggests plumbing backflow.
- Closing only one supply valve can help a technician understand which inlet path is involved, but both should remain closed when the appliance is unattended.
- A drain hose inserted too deeply or a backed-up standpipe can return water to the washer and should not be mistaken for commanded filling.
Checks that preserve the evidence
- Close the hot and cold water valves and contain any water before it reaches the rim or floor.
- Note the color, odor, and timing of the water without tasting it or reaching into an energized appliance.
- Inspect the visible standpipe and drain-hose position for backup evidence, keeping the hose installed to the model requirements.
- Leave the supplies closed and arrange service or plumbing help based on whether the source appears to be inlet water or drain backflow.
Normal behavior or a fault?
If the level stops rising when the supply valves close, the water-supply path needs model-specific appliance diagnosis. If household wastewater is returning through the drain, the standpipe or plumbing system is the next priority. Either condition should be corrected before another load.
The safe service boundary
Do not leave the washer with open valves, do not energize it to see whether more water arrives, and do not remove internal panels. Water near outlets or cords requires power isolation from a safe dry location and professional help.
Why this needs a separate answer
Off-state water entry has a distinct safety response and diagnosis from overfilling during a controlled cycle. The “washer fills with water while off” question is therefore best answered within the documented Top-load and front-load washing machines scope. The checks above stay focused on stop uncontrolled filling and distinguish an inlet path from drain backflow; they do not turn one visible symptom into a confirmed part failure or import an undocumented control sequence from another platform.
