Well, here’s some truth for you. A lot of your dishwasher problems don’t have anything to do with your dishwasher — they have to do with you.
No other appliance operates with so many variables, many of which you can affect: the amount of dishes, the amount of soil, the amount of detergent and rinse aid, dish placement, etc.
Before you get all huffy because you spent X-hundred amount of dollars on the darn thing, understand that little, tiny changes to the way you do things will improve the cleaning results of your dishwasher immensely.
If you do nothing else differently, here’s the best dishwasher hack: just before you turn on your dishwasher, run your faucet until the water is steaming hot.
Otherwise, the water pumped into your dishwasher will be cold from sitting in your copper pipes. This way, you start with steamy water that has the best chance of reaching the high temperatures necessary for cleaning and drying completely. Water needs to be heated to 140-degrees Fahrenheit to dissolve food messes and disinfect dishes.
