your supply taps could be not shutting off completely or more likely a bit of dirt/grit has come through the water inlet pipes and got stuck/jammed in the inlet solenoid rubber preventing the water from not turning off. If you have 2 taps turn off 1 at a time does the machine fill? repeat for the 2nd tap. change the solenoid which causes the machine to fill
I am assuming this machine is NOT CONNECTED to the SINK U BEND as this can also fill the machine
