Today's tip is how to keep your dishwasher running in tip top shape. You should do this a few times a year. I just did it last week. Pour white vinegar in the detergent tray and the hole where you would keep your rinse aid and run EMPTY on pots and pans cycle. This will clear out any junk you may have in the lines.
Another tip is before starting any new load, always run hot water in the drain and turn your disposal on and run it for 30 seconds. This will flush the lines so that the food in your drain doesn't end up running through the lines in your dishwasher.
That's my short, but sweet tip to keep your dishwasher happy.
