Claim 9:
10. A washing machine appliance, comprising:
a wash tub positioned within a cabinet;
a wash basket rotatably mounted within the wash tub and defining a wash chamber;
a motor assembly operably coupled to the wash basket for selectively rotating the wash basket;
a drain pump assembly fluidly coupled to the wash tub for selectively draining wash fluid from the wash tub;
a fluid level sensor configured to generate a fluid level signal corresponding to a fluid level at the wash tub; and
a controller operably coupled to the motor assembly and the drain pump assembly, the controller being configured to:
rotate the wash basket to at least a desired speed;
determine whether an energy parameter threshold of the motor assembly is exceeded when rotating the wash basket within a period of time; and
generate an output signal corresponding to fluid detection at the wash tub when the energy parameter threshold is exceeded when rotating the wash basket within the period of time; and
generate a sensor fault signal indicative of fluid level sensor failure when the fluid level at the wash tub is determined by the fluid level sensor to be above a fluid level threshold and when at least the desired speed of the wash basket is achieved within the period of time.
