Abstract

The invention relates to a household appliance (1) for the care of laundry items, with a tub (4) in which a laundry drum (3) designed to hold the laundry items is arranged, and with a pump system (7)which comprises a circulation pump by means of which a fluid can be conveyed from a lower region (13) of the tub (4) into an upper region (14) of the tub (4). A control device (20) provided for controlling the circulation pump is designed to determine a delivery rate of at least the circulation pump on the basis of at least one operating parameter of the circulation pump. The household appliance (1) comprises a flow measuring device (23), by means of which a flow of the fluid through a line (16) of the pump system (7) can be detected, via which the fluid can be fed to the circulation pump. Thecontrol device (20) is designed to take into account at least one measured value of the flow measuring device (23) when determining the delivery capacity of the circulation pump. The invention further relates to a method for operating such a household appliance (1).
