I've checked water inlet hoses and hose beneath unit. All are clear. The problem is the washer KEEPS FILLING (overfilling) until the LF error and then stops. Then I press Power and the unit drains. For some reason, it will not stop filling until this error occurs roughly 5-7 minutes into the wash cycle. And because it's overfilling, when the unit drains, some water pools and overspills onto the floor during the draining. The machine works fine on the Rinse/Spin cycle selection. What is the diagnosis for this?

Replace the water level pressure switch.
