The domestic appliance 9 has at least one fill level sensor, wherein the at least one fill level sensor comprises at least one optical fill level sensor 1; 11; 21; 31 includes. The method is used to determine at least one state parameter, in particular a fill level h, of a liquid F in a domestic appliance 9, the method comprising at least the following steps: coupling light S into at least one light guide 2, the at least one light guide 2 at least partially is wettable by the liquid F; Decoupling light from the at least one light guide 2 into at least one light sensor 7 and determining at least one state parameter, in particular a fill level, of the liquid F in the domestic appliance 9 on the basis of measurement data of the at least one light sensor 7.
