Question about KitchenAid Dishwashers
A heavy film can be the product of bad water conditions, bad cleaning action from the machine, incorrect/inadequate chemistry, and even water temps being too low.
Start by washing some of the dishes by hand to determine if the film can be removed. Use a quality detergent and some elbow grease. If film can be removed, test the machine for proper washing action. I like to do this by coating the inside of several glasses with mayonaise and placing them strategically throughout the machine. Run a cycle and ensure ALL mayonaise is removed. Is mayo removed? If no, check for plugged wash arm jets or screens. If yes, check for good water temps. 120F or higher is best, depending on machine type/model.
If machine is good and film is removed by hand, then you either have a water problem (water hardness, TDS, etc), a temp issue (raise temps above 120F), or a procedural issue (improper loading of wares, inadequate/insufficient detergent, too much food soil entering dishmachine).
Hope this helps,
