In a medium sized mixing bowl, stir together the ketchup, brown sugar, vinegar, Old Bay seasoning, and the liquid smoke.
Place the ribs in the bottom of your Instant Pot and pour the sauce on top.
Pour the water on top, but don't mix it in with the other ingredients.
Place the lid on top of the Instant Pot and move the valve to SEALING. Press the MANUAL (PRESSURE COOK) button and set timer for 25 minutes.
When the timer is done, let the pressure do a NATURAL RELEASE (this will take about 20 minutes).
Remove the lid and serve.

To make this into a freezer meal, place ribs, ketchup, brown sugar, vinegar, liquid smoke, and seasoned salt into a gallon-sized freezer bag. Place freezer bag into freezer and it will last up to 90 days. When ready to use, dump ingredients from bag into Instant Pot and add .5 cup of water in with the frozen food. Place the lid on top, move the valve to SEALING, and press the MANUAL button. Set timer for 45 minutes. Let the pressure do a NATURAL RELEASE when the timer is done. Follow the rest of the instructions as written.
