1. A laundry washing machine appliance, comprising:
a wash basket rotatably mounted within a tub, the wash basket configured to receive laundry articles;
a pump assembly configured to drain fluid from the wash basket;
one or more sensors configured to obtain a pressure value, a humidity value, or both; and
a controller configured to store instructions that, when executed, causes the appliance to perform operations, the operations comprising:
operating the pump assembly to perform a drain cycle;
determining a pressure value over a period of time during the drain cycle;
determining whether the pressure value over the period of time decreases at or above a pressure threshold rate; and
operating the pump assembly in a preset cycle mode when the pressure value over the period of time is below the pressure threshold rate, wherein the preset cycle mode comprises operating the pump assembly for a predetermined period of time during the drain cycle without utilizing pressure values from the sensor.
