If you don’t see any water dispensing while pressing your sparkling dispense button, then you need to replace külCO2.

You should see around 250 – 8oz. glasses of sparkling water, which replaces 125 – 16 ounce bottles.


kül Ultimate removes a long list of contaminants including Pharmaceuticals, Asbestos, Chlorine, and Lead. Please visit our filtration page for a full list of contaminant reduction.

kül’s filter life monitor will alert you when it’s time to replace your filter. Since water quality varies, those areas with heavy sediments may find that filters clog, and the water will dispense slower. Replacing your filter will restore normal flow.


If the water coming from the faucet seems slower than normal, it might be time for a filter change. In some areas the water quality may cause your filter to expire before the year point. If you have changed your filter and are still experiencing low kül flow, please call the kül Tech Squad.

If you press any of the dispense buttons on the touch screen and don’t receive any water, there are several items to check. Make sure the filter is installed in the fully locked position. Also, make sure your Shut-Off Valve in the back is in the ON position and your water line is functional.

If this doesn’t solve the problem, there might be an issue with another area of the kül. Contact the kül Tech Squad for further diagnosis.

Tip: When cleaning the kül, be careful to keep water away from the Touch Screen area and avoid detergents – clean the kül with mild soap and a damp towel. Moisture can damage the Touch Screen and require more frequent replacement.
