Abstract
An electric household appliance has a chamber that is at least partially filled with liquid during operation of the appliance. A motor drives a pump for drawing liquid from the chamber. A monitoring device detects the rotational speed and the power of the motor, compares detected values for the rotational speed and power to a predefined characteristic, and signals an exceptional state if the comparison indicates that the detected values deviate significantly from the characteristic.
