How many rows of tines are on the bottom rack? Is there a heating element?

This unit features easy-to-use system of adjustable tines and rack height provides more flexibility and versatility when loading dishes of various shapes and sizes. The number of tines in the lower rack are not specified in the Owner's Manual. The dishwasher does not rely on a heating element for the drying process; instead, it relies on the heat that is retained by the dishes and the tub during the wash and rinse cycles to turn the moisture in the tub into humidity. ^Daphane
