If your dishwasher isn’t drying, just know that your dishwasher drying problems might be completely fixable.
The No. 1 cause of wet dishes is lack of rinse aid, or drying aid as I like to call it.
Most think of rinse aid’s aesthetic benefits, because it helps water “sheet” off dishes rather than forming water droplets that cling and leave icky spots.
But modern dishwashers are designed to use rinse aid for drying, so without it, your dishes and dishwasher interior will have excessive moisture. Also, the heated dry option will not perform as well without rinse aid. (Now is a good time to check if your dishwasher includes a Heated Dry – or Extra Dry – option you might not be using.)
Once you fill your rinse aid dispenser, don’t forget to refill it. A full dispenser will last about a month, but I top mine off every couple weeks.
Proper loading also ensures good drying performance. Load items, especially plastic, at an angle so water can sheet off. Plastics have a porous surface and tend to collect droplets, so they take longer to dry and might not dry completely in a normal dry cycle.
For best results, the water should be 120 degrees F as it enters the dishwasher – not lower or higher by much. If your water heater is located far from the dishwasher, it may be necessary to run the hot water at the faucet closest to the dishwasher to minimize the amount of cold water in the water line.
