Upper Tray Levels-Dishwashers
Dishwashers have two trays to hold soiled utensils. The upper tray levels are the number of options of levels at which the upper tray can be fitted. The lower tray is at the bottom of the machine and is fixed. The upper tray is either fixed or adjustable. Adjustable levels are more convenient for users since it can be adjusted to fit in larger utensils like thalis, pans and kadhais. Only one upper tray level indicates that the upper tray is fixed.
