When troubleshooting a draft system, which component is NOT essential to check?

In a draft system, ensuring optimal performance involves checking several critical components, but the cleaning schedule is not directly involved in the immediate troubleshooting process. While system cleaning is essential for maintaining quality and preventing issues like off-flavors or blockages, a troubleshooting scenario typically focuses on components that can affect draft pouring and beer quality in real time.

The temperature of the beer lines is crucial, as it directly impacts the pour quality and can lead to issues such as excessive foaming if not maintained correctly. Engaging the coupler is equally important because if it is not properly connected to the keg, no beer will flow, rendering the system inoperative. Lastly, confirming beer availability in the keg is fundamental to ensure that the draft system can dispense beer at all; if the keg is empty, there won't be any beer to pour.

While the cleaning schedule should never be overlooked for long-term system health and quality assurance, it is not an immediate factor to check when trying to resolve a service issue on the spot.
