Water bottle does not empty into the base; unit runs dry quickly and shuts off.

Safety first: Turn off and unplug the unit before removing the bottle.

• Test valve flow: Remove the bottle cap and press the valve stem over a sink. Water should flow freely. If not, soak the cap in vinegar to dissolve scale and rinse thoroughly.
• Clear vent hole: Ensure any small vent hole in the cap is not blocked by debris or scale.
• Check float movement: In the base, verify that the float (if equipped) moves freely up and down. Clean off mineral buildup.
• Properly seat bottle: Refill the bottle, install the cap, and place it squarely on the base. Push down until you see a steady stream of air bubbles.

If the bottle still does not empty, replace the bottle cap/valve assembly.
