Hi carlos. Initially it would be necessary to know the model of the machine to be able to help you correctly. For what you say, it makes me think that the washing machine is indicating an overfill error, even more so if you decide that the drain pump is turned on. If the error appears without water in the tank you should initially check the proper functioning of the pressure switch, that your hose is healthy and free of obstructions and the continuity of its wiring and connectors. Greetings.
