Method for operating a dialysis system

A method of operating a dialysis system comprising a plurality of hydraulically connected components and a control device, the method comprising the steps of:

• receiving, by the control device, component operating data from the components, the component operating data comprising at least demand data for an upcoming task to be performed by the respective component;
• determining an expected resource consumption of the component based on the demand data;
• monitoring, by the control device, of an actual resource consumption of the components;
• determining, by the control device, a deviation of the actual resource consumption from the expected resource consumption;
• and
• detecting, by the control device, a leakage in the dialysis system if the deviation is outside a predetermined range.
