Right off the bat, I can think of three things that may cause this.
1. The air admittance valve under the sink has failed. If it doesn't open, it will significantly affect drainage. Solution: Replace AAV.
2. The holding tank is full. Have you pulled all three drain handles?
3. There is debris in the plumbing. Most likely, it's stuck in the trap. Solution: unscrew the trap and physically examine it. Since it's a pretty new unit, it could be construction debris.
