Pressure sensing assembly for a washing machine appliance

A washing machine appliance comprising:

• a wash tub positioned within a cabinet and defining a wash chamber and a sump;
• a wash basket rotatably mounted within the wash tub for receiving a load of clothes;
• a dispensing assembly mounted within the cabinet for selectively adding wash fluid into the wash tub;
• and
• a pressure sensing assembly in fluid communication with the sump of the wash tub, the pressure sensing assembly comprising:
• a sensor housing mounted to the wash tub, the sensor housing defining a fluid inlet in fluid communication with the sump, an air chamber positioned above the fluid inlet along a vertical direction and being in fluid communication with the fluid inlet, and a sensing chamber in fluid communication with the air chamber, wherein the sensor housing defines a dividing wall that extends upward along the vertical direction within the air chamber;
• and
• a pressure sensor mounted within the sensing chamber for detecting an air pressure of the air chamber.
