Skip the dishwasher for the interior surfaces where your food touches, even though the enamel technically can handle it. the reason is that repeated hot cycles and harsh detergent can dull that gorgeous red finish over time, and once it starts looking cloudy or stained in there, it's tough to restore. the exterior and lid are fine in the washer if you really want, but honestly your stew pot deserves better than that treatment.
Hand washing takes maybe two minutes if you do it right - just wipe it out while it's still warm with some hot soapy water and a soft sponge, then dry it. I've seen too many beautiful pieces lose their luster because people got lazy about it. your pot isn't like a regular pot; it's an investment that'll outlast most things in your kitchen if you treat it decent. the enamel isn't like seasoning on raw cast iron that needs protecting either - it's a protective layer itself, but that doesn't mean the dishwasher is the best choice just because it *can* survive it.
