Place all ingredients into the pressure cooker inner pot, stir and secure lid, ensuring the valve is turned toward sealing. Set timer to 20-30 minutes, depending on how soft you like your beans. The longer the softer.
When cooking cycle is complete, let naturally release for 5-10 minutes, then release remaining pressure.
Remove lid, drain beans or remove with slotted spoon. Remove ham hock and bay leaf and serve warm.
