water stays at one level, low

It does show on the parts break down that there is a pressure hose as well as a pressure switch that I mention on the first answer. I have attached the link for the pressure hose. It is number 5 on the diagram.

Hi. The pressure switch is what controls the amount of water the washer gets. p# W10544357. When I looked up a photo of this part it did not look like a pressure switch to be. When you select the different load sizes on this unit you still get the same amount of water?

Sounds like you could have an issue with the pressure switch or pressure hose witch attaches from the switch to the tub. This hose could have a hole or could be clogged. It doesn’t sound like there is an issue with the hose but check to be sure. Sounds like the switch. Make sure you have good water pressure to the unit on hot and cold.
