Abstract

Provided herein is a method performed by an appliance for washing and rinsing goods of detecting process water added to a sump of the appliance during interruption of operation of the appliance, upon recommence of appliance operation, and an appliance performing the method. The method may include detecting process water added to a sump of the appliance during interruption of operation of the appliance, upon recommence of appliance operation. The method may include increasing operating speed of a circulation pump of the appliance to a target speed, measuring an indication of circulation pump pressure or process water flow rate through the circulation pump, and determining that process water has been added to the sump of the appliance during the interruption in case the measured pressure or flow rate is maintained at a sufficient level after the speed of the circulation pump has reached the target speed.
