Auto and heavy lights starts flashing after the cycle runs for 15~20 mins and when try to stop the cycle the water is continuously flowing inside and is not stopping. I had to shutoff water supply. Is the water valve bad ? Or pcb is bad? Any guidance on how to change water inlet valve ?

Probably the water valve. Connect your meter to the water valve and check after the fill cycle the voltage drops to 0V. If the valve is still open, replace it. If the voltage remains at 120 VAC replace the control.
