I have seen the internal view of dishwasher how its working, its just spary water and soap, detergent acid what ever we used, but logically it wont work good, you can’t use the dishwasher to clean the milk pan, if its hard, It can be used to wash the same type plates in hotels before its became dry.
my suggestion pay for maid or wash your self and don’t waste money in dishwasher its not at all useful for Indian kitchen,
Think Twice thrice before buying dishswasher.
