What could be a reason for no beer at the faucet in a direct cooled system?

In a direct-cooled draft system, both the condition of the beer lines and the source of CO2 can significantly impact whether beer flows at the faucet. If the beer lines are dirty, it can lead to blockages, restricting the flow of beer. Similarly, if the CO2 bottle is empty, there wouldn't be enough pressure to push the beer from the keg through the lines and out of the faucet.

Choosing both options as possible reasons recognizes that multiple factors can contribute to the lack of beer dispensing from the faucet. This understanding is crucial for troubleshooting draft system issues effectively. Assuring that you maintain clean lines and monitor CO2 levels is vital for the proper functioning of a draft beer system.
