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.
