Cut rib rack into 3-4 rib sections. Suggested: the center ribs in 3 rib sections, ends in 3-4 rib sections because they're smaller.
Rub the rib sections with the dry rub powder.
Combine water, Worcestershire sauce, and soy sauce in a cup, then pour into the Ninja Foodi ceramic pot.
Place the rib sections in the Foodi air crisping basket. Make sure the plastic diffuser is attached to the air crisping basket. Arrange the rib sections to stand vertically in the basket, around the perimeter, with the meat facing the center of the pot.
Make sure the silicone seal is properly seated in the rim of the pressure cooking lid, then attach the lid to the main Foodi body. Set the SEAL/VENT knob to SEAL.
On the front panel, turn on the power, select PRESSURE and set the time to 20 minutes. Press START.
When the pressure cooking phase is complete, leave the unit alone until the timer counts up to 10:00 minutes. Then carefully turn the SEAL/VENT knob to VENT.
When the pressure is completely released, open the Foodi. Remove the ribs from the air crisper basket, then carefully remove the basket and the ceramic pot. Carefully empty the liquid from the ceramic pot and return the pot and the crisper basket to the Foodi body.
Baste the ribs with the BBQ sauce and return the ribs to the crisper basket, again arranging as previously done.
Close the Crisper lid. Set the front panel to BAKE/ROAST, 375 degrees, and 12 minutes. Press START.
When the timer expires, serve the ribs!
