A washing system for determining an operating state of a dishwasher comprises a dishwasher, in particular wherein the dishwasher comprises a dishwasher interface, a dispenser unit, in particular wherein the dispenser unit comprises a dispenser interface, wherein the dispenser unit is connected to the dishwasher for dosing a detergent to the dishwasher, a logic unit, in particular wherein the logic unit is connectable to the dishwasher interface and the dispenser interface, and a current sensor for measuring an electrical current consumed by the dishwasher, wherein the current sensor is connected to the logic unit. By replacing costly water meters by a current sensor, the cost efficiency of the washing system may be increased. In addition, the assembling and maintenance effort of the washing system may be reduced.
