An air dome and air pressure sensor of the present invention are adapted to determine the level of water in a wash tub. The air dome is located within the wash tub and positioned such that water left in the sump will not enter and remain trapped in the air dome when the washing machine is tilted. The air dome may be comprised of an angled tube having a downward facing open end and being in communication with a pressure sensor via an air dome hose. The angled tube extends downward into the drain tube of the washing machine in such a way that water will not enter and be trapped in the air dome. The air dome may also be comprised of a downward facing air trap in communication with the air pressure sensor via an air dome hose. The air trap is also located within the wash tub and oriented so that water will not enter and be trapped in the air dome when the washing machine is tilted.
