Beverage appliance

A method of controlling an appliance for making a beverage having at least one beverage making component using liquid for making the beverage, a liquid flow path integrally formed with and providing the liquid to the at least one beverage making component and a filter assembly configured for the appliance and filtering the liquid in the liquid flow path, the method comprising:

• determining a first electrical signal indicative of a degree of purity of untreated liquid in the liquid flow path;
• determining a second electrical signal indicative of a degree of purity of treated liquid in the liquid flow path, the treated liquid being provided to the at least one beverage making component;
• and
• monitoring performance of the filter assembly based on the first electrical signal and the second electrical signal.

An appliance for making a beverage, the appliance comprising:

• at least one receptacle configured to receive liquid;
• a sensor assembly configured to generate an electrical signal indicative of ionic content of the liquid in the receptacle;
• and
• a controller coupled with the sensor assembly and configured to control descaling of the appliance, wherein the controller is configured to:
• determine a first ionic content value indicative of ionic content of the liquid in the at least one receptacle of the appliance based on the generated electrical signal;
• determine whether the appliance is in a descaling mode;
• in response to determining that the appliance is in the descaling mode, determine a type of a descaling agent based on the determined first ionic content value;
• and
• control descaling of the appliance based on the determined type of the liquid.
