Abstract (en)
Method for detecting faults in electric appliances operated with water preferably a washing machine or a dishwasher in which an electric resistive path (R water ) to ground / earth (GND) is temporary created by water flowing in the appliance or by water drained from said appliance, the resistive path (R water ) created through water is supplementary to the normal electrical connection to ground / earth (GND) and allows detecting abnormal conditions when said electrical connection to ground / earth (GND) is not present.
