I can't seem to be able to control the fill water level. No matter what level I choose, it fills above the highest level. I set it on lowest level and it fills to the highest level or above. 745G Model LAT5005AAW

This is caused by a faulty water level switch. It is a diaphragm-like device that has a small clear plastic tube attached between the switch and the bottom of the washer's outer tub. As the water level increases, so does the pressure on the air in the plastic tube and when it reaches a certain level, it activates the switch to turn off the water and signals the timer to start the appropriate cycle. Check for any obstructions in or damage to the plastic tube. The switch can be tested using a multimeter or ohmmeter. Check for continuity. A lack of continuity indicates a faulty switch. Hope this helped and best wishes.
