Thank you for your question and I understand your concern.
If the water entering would not shut off by pushing the timer knob in or by disconnecting the power cord the water inlet valve on the back of the washer has stuck open and it will need to be replaced.
In order toe access and replace the water inlet valve the washer cabinet must the taken off the base. I added a YouTube video showing how to remove cabinet. Once the cabinet has been removed you will see the water inlet assembly which includes the Vacuum break and thermistor located the center top area.
Note: Disconnect the power cord and disconnect the hot and cold water fill hoses from the back of the washer.
There might be one or two screws to remove on the back panel before the water valve and vacuum break can be removed from the front. The par number of the water inlet valve assembly is W10144820 which can be ordered from
