We bought the whirlpool cook top stove with aqua lift auto cleaning fall 2018 from Lowes in Dubuque, Iowa this cleaning system does not work at all, we have tried to clean it as directed, does not clean anything of inside of oven, we have bought whirlpool products over and over again over 50 years now, I have never seen anything like this before, this is without a doubt the worst problem we have ever seen, and we would expect to have it replaced with a new stove without this feature, I can't believe that they could market this as self cleaning, this feature is very necessary because we can't physically do the cleaning ourselves, which is why we bought self cleaning, this is deliberate False Advertising, Ken & Bev Petty
