Claim:
A method for executing a washing program in a household dishwasher, the method comprising: within the dishwasher having: a housing having a washing compartment; a crockery retainer that statically retains crockery that is to be washed in the washing compartment of the dishwasher; a flow section, which is disposed within the housing of the dishwasher, that circulates a washing liquid therein to be subsequently sprayed onto the crockery as a washing program is executed, wherein the flow section heats the washing liquid to a predetermined temperature; and a spray system for spraying the washing liquid onto the crockery that has been disposed statically in the dishwasher only after the washing liquid has been heated to the predetermined temperature by the flow section, wherein the flow section is separate from the spray system such that the washing liquid does not substantially impinge on the crockery in the washing compartment of the dishwasher as the washing liquid is being circulated and heated in the flow section, and wherein the flow section includes: a valve circuit controllable by a program control system and forming a substantially closed circuit that circulates the washing liquid; and a heater for heating the washing liquid being circulated in the valve circuit of the flow section to the predetermined temperature only in the flow section, providing the washing liquid to be eventually sprayed by the spray system, as the washing program is executed, onto the crockery in the dishwasher; heating the washing liquid to the predetermined temperature in the flow section that is separate from the spray system to an extent such that the washing liquid does not substantially impinge on the crockery in the dishwasher as the washing liquid is being heated in the flow section, whereupon the washing liquid is heated without substantially wetting the crockery in the dishwasher; and after the washing liquid has been heated to the predetermined temperature, delivering the washing liquid into contact with the crockery in the dishwasher, whereupon the crockery in the dishwasher that essentially has not essentially been heated is heated by the washing liquid.
