I am having problems with my washer not filling up to capacity when starting a load of laundry. It doesn't matter if I am washing a "small" load or a "large" load of laundry the outcome is still the same. Is there a "float" or something that needs adjusting that would be easy enough for me to attempt myself? Any suggestions?

The load size selector switch is also known as a pressure switch. There is a hose that goes from the washer tub to the switch. You can gain access to it from behind the control panel. Pull the hose off and blow through it to make sure it is clear. You can blow bubbles back into the tub (if there is water in it). Drain the tub and re-attach the hose. Fill again. If this does not fix your problem you need a new pressure switch.
