I have a few coin Whirlpool washers CAM2752TQ3 and when the button is pressed for large load the water is not filling the whole tub. I know that there are 2 switches for this washer a Low pressure switch W10414162 and a High pressure switch W10414164. Would it be the low or the high switch that would be causing the tub not to fill. I am new at repairing these machines.
