A Samsung WV55M9600 FlexWash that keeps taking in water when it is turned off, or finds water in a drum that you did not fill, has a stuck or leaking water inlet valve, and the first step is the same whichever washer is affected: turn off the water. This model is two washers in one cabinet, a full front-loader below and a small top-loader in the lid above, and each has its own water path, so you first need to identify which washer is filling.
The checks in more detail
Look at the upper drum and the lower drum separately and note which one has water in it when the washer is off. The cause is almost always an inlet valve that does not close fully. Each washer has solenoid valves behind the back panel where the hoses connect; when the washer is off the valves should be shut. Sediment or a worn seat can hold a valve slightly open, and water trickles in until the tub is full, or it continues to fill after a cycle ends.
A full tub that you did not ask for is not a control fault. Close the hot and cold taps at the wall whenever the washer is not in use until it is repaired, which prevents a flood, and drain the tub by running a drain cycle or through the filter. Check the simple things. Make sure the water supply hoses are connected to the correct valves, hot and cold, and that nothing is leaking at the hose fittings; a leaking hose looks like a filling drum.
Clean the small inlet screens where the hoses join the washer, because debris on the valve seat can cause the leak-through. If cleaning the screens does not stop it, the inlet valve is faulty and needs replacing, which Samsung service does with the model number WV55M9600AV from the label. Because the two washers run independently, only the valve of the washer that fills is the one at fault. Do not leave the taps open when you go out until it is fixed.
