I'm not sure what to try next. The washing machine will not fill high enough when set to Super. I replaced the air tube which I definitely thought was the problem since it was moldy. That didn't fix it. I then replaced the pressure switch and that didn't solve it either. All the cycles work correctly such as agitate, drain, spin, rinse. One trick I do to get the water higher is hold the knob on the load size between middle and Super, it will continue to fill up. Then it stops when you release it back to Super. The air chamber on the side of the tub that the pressure tube connect into looked fine to me as well.
