METHOD OF DETERMINING WHETHER PROCESS WATER IS PRESENT IN A CIRCULATION PUMP OF AN APPLIANCE FOR WASHING AND RINSING GOODS, AND APPLIANCE AND COMPUTER PROGRAM THEREWITH
Provided herein is a method of determining whether process water is present in a circulation pump of an appliance for washing and rinsing goods, and an appliance performing the method. The method of determining whether process water is present in a circulation pump of an appliance for washing and rinsing goods may include measuring a minimum value of a property representing load of the circulation pump at a predetermined first speed, measuring a maximum value of a property representing load of the circulation pump at a predetermined second speed, the second speed being higher than the first speed, determining a relation between said minimum value and said maximum value, and determining, from said relation, whether process water is present in the circulation pump.
