Direct answer
Water entering an idle washer points to a supply-valve or inlet-valve problem, not a cycle setting. Close both wall valves to stop the flow and identify whether the water is clean supply water or drain backflow.

- ×Account ownership, billing or warranty disputes
Observe before changing anything
ReversibleNote whether the water is clean and whether it enters with the wall valves open but the washer powered off.
Isolate the failing boundary
ReversibleClose both supply valves. If water stops, the inlet path is implicated; if dirty water appears from the drain side, inspect drain installation and household plumbing.
Apply the narrow correction
ReversibleLeave the supply valves closed between uses and arrange the exact-model inlet-valve or plumbing repair.
Verify the result and stop at the boundary
ReversibleStop immediately if water threatens electrical parts or continues with both household valves closed.
