Unusual Taste or Odor: This often indicates that the carbon filters (GAC, CTO, Post Carbon) need replacement. Ensure proper flushing after new filter installation.
Leaking: Turn off the water supply immediately. Check all connections for tightness. Ensure O-rings are properly seated and not damaged.
No Water Production: Verify the water supply is on and the feed water adapter is open. Check the tank's air pressure. The RO membrane might be clogged.
