A dispensing device for liquid and/or powdered treating agents includes a compartment for holding a first treating agent. A first nozzle is disposed above a lateral region of the compartment and configured to convey water therethrough onto the first treating agent. A second nozzle is disposed above a central region of the compartment and configured to convey water therethrough onto the first treating agent. A receptacle configured to hold a second liquid treating agent can be inserted into the compartment so as to form a gap between a wall of the receptacle and a wall of the compartment. Introduction of water through the first nozzle and the second nozzle is selectively controllable.
