Abstract

A washing machine appliance includes a wash tub defining a wash chamber for receipt of a load of articles for washing and a water control valve for regulating a flow of water from a water supply into the wash chamber. A controller is configured for detecting a low water level in the wash chamber, e.g., due to a low water supply pressure, by obtaining a target volume and a fill volume; obtaining an underfill limit based at least in part on the fill volume; obtaining a tub water level after attempting to fill to the target volume; obtaining a new fill level if the tub water level is less than the underfill limit; and filling the wash tub to the new fill level.
