I guess your washing is still in there as well. Since you don't say what kind of machine you have it complicates things slightly but follow this general fix.
Have your user manual on hand. Open the flap at the bottom front - find the emergency drain hose & empty the water into a bucket or similar - activate the emergency door release (either a white plastic screw type or pull ring) - door opens, retrieve washing - open filter & check for foreign objects in there. If you find a blockage fine, if you don't suspect either a blocked sump hose or defective pump. Good luck
