Washer ran all over the floor after filling up and didnt stop filling

Well, there are two main possibilities: Inlet valves and pressure sensor system. to test the inlet valves, turn off the machine, do they stop? Dirt can keep them open.
If power off stops the water, I suspect the pressure system. There is a component outside at the bottom of the drum that measures the water volume, using pressure. This collector component sometimes gets clogged with detergent. If it is open, test the transducer at the other end of the plastic hose. The system is designed to stop the power to the inlet valves when the pressure builds.
