If your beer dispenser is not performing as well as usual, it may be time for some draft beer system troubleshooting. We understand the importance of serving the perfect pint, and maintaining your system is crucial to achieving that goal. Even the best-maintained systems can encounter problems, but with a little know-how, you can keep your beer flowing smoothly. Let’s dive into some of the most common issues and how to address them.


One of the most frequent issues encountered is improper beer temperature. Draft beer should typically be served between 36-38°F to ensure optimal taste and presentation. Temperature fluctuations from keg to glass can lead to foamy beer or off-tastes. It’s essential to maintain consistent temperatures throughout your system to prevent these issues. Allowing kegs to rest in the refrigerator before dispensing and ensuring there are no warm spots along the beer lines can help maintain ideal temperatures.


Correct pressure is vital for maintaining carbonation levels and preventing excessive foaming. CO2 pressure between 12-15 lbs is generally recommended for most ales and lagers served at 36-38°F. Adjusting pressure based on the type of beer and elevation can help ensure optimal carbonation levels. Too much or too little pressure can result in foamy or flat beer, so it’s important to dial in the correct pressure for your specific setup.

System Maintenance

Regular cleaning and maintenance of your draft beer system are essential for preserving the quality and flavor of your beer. Components such as faucets, beer lines, and keg couplers should be cleaned every two weeks or with every keg change. Bypassing cleanings can lead to cloudy beer, off-flavors, and gunk build up. By following a regular cleaning schedule and utilizing proper cleaning products, you can ensure your beer stays brewery-fresh with every pour.

Faucet Operation

Proper faucet operation is crucial for achieving the perfect pour. Opening faucets slowly or incorrectly can lead to excessive foam. Ensure your system’s faucets are opened quickly and fully to minimize foaming and achieve a clear pour. Correcting any issues with faucet operation can help prevent wasted beer and ensure customer satisfaction.

Troubleshooting Checklist

Most dispensing problems can be traced back to improper temperature, pressure, or cleaning issues. Before troubleshooting specific problems, check that your kegs are stored at the correct temperature, the CO2 pressure is within the recommended range, and all system components are regularly cleaned and maintained.
