It is a misconception that our Whirlpool dishwashers can handle whatever food left on the dishes. Anything we load into the dishwasher (aside from the dishes) has to go somewhere and it usually ends up in our drain lines, drain pumps, sumps and air gaps. Frequently, when dishwashers are either having trouble draining or are leaking, it is because particles of food, stems, pieces of that glass that broke and labels have made their home in our dishwashers draining components. To avoid the clogs, we need to be diligent in getting the pieces of food and stems off of our dishes before putting them into the dishwasher.
Additionally, there has been a rumor floating around the internet that the best way to get labels off of glass jars and such is by running them through the dishwasher. Yes, this will remove the stickers by sacrificing the functionality of our dishwashers. The sticky labels get stuck in the drain pump and will cause it to burn out over time. The best way to remove labels without ruining our appliances is to soak the jars in very very hot water. If the container with the label is plastic, you fill it up with the hottest water that comes out of the faucet. If the container is glass, you can actually heat water up in the microwave or heat water from a tea kettle and pour it into the container. Either route you go, let it sit for 20-30 minutes, then the sticky part is easier to remove. It may not be as clean as the dishwasher trick, but it will save a pretty penny, in the end.
