Bosch Dishwasher keeps filling with water when not in use

Dishwasher works fine. However it keeps filling with water (I think it’s clean water) when not in use. It fills to the point where is runs up and over into the floor when I open the door. Please help!

in most cases replacing fill valve solves problem .remove bottom panel ,fill valve is on left side .i find removing door shell gives much more room to work. you will need torque screw driver for that, do not remove control panel screws
