OK, here we go. If yo have B button pushed in and turn the dial to B position, you will get a prewash, main wash, and two rinses. That would be referred to as Normal Wassh cycle. Button B pushed in and the timer dial moved mini-wash, you will get the main wash and two rinses. That would be referred to as light soil or low energy cycle. Now, with the two buttons over A The left button is for Pots and Pans. If this machine follows teh standard whirlpool cycle sequence, A with Pots and Pans button selected, you will get a PreWash that will heat the water to a certain temperature, then a rinse, then the main wash and will be eated to a set temperature; after the main wash will be the two rinses. The 2nd of those two rinses will also heat the4 water to a set temperature. While the machine is heating the water on the Pots and Pans cycle, it will continue to circulate the water and wash the load and the timer will be paused until the temperature is set. The left of the two buttons over is for Heavy soil. It's the sequence of the Pots & Pans cycle, but no cycle delay for heating wateer. So its Prewash, ri8nse, main wash, and two rinses. There is another little cycle between the two words "off" on the dials. Taht is a rinse & hold cycle to prewash a partial load dirty dishes and hold them until you are ready to run a full load through a complete usual cycle. If the machine is functioning properly, this is probably the best cleaning dishwasher ever made, particularly with the Pots & Pans cycle. The joke is that it would take the chrome off a trailer hitch or the chrome off a truck bumper. Would llvoe to see a picture of the interior.
