I dont know amigo, I have never had issues with a properly loaded dishwasher not cleaning dishes properly, no smell, no residue, no issue..
yes when someone loads the dishwasher improperly…yeah
I have seen people who want to overstuff the dishwasher, and then run it on speed cycle, well yeah then u are not going to get things cleaned properly. or if the water is too hard then it will not work with detergent too well, or the stuff is really baked on and left to become crisp.
so peeps, load the dishwasher properly and if the dishes are heavily soiled run the dishwasher on a diff setting.
