Beer system troubleshooting
Common commercial beer-system symptoms and the system areas that should be checked.
Fault diagnosis
Beer not pouring?
A stopped tap can be caused by gas supply, couplers, frozen or blocked lines, failed pumps, empty kegs, refrigeration faults or control issues.

Beer pouring too foamy
Persistent foam usually points to temperature, pressure, restriction, dirty glassware, line condition or equipment issues rather than a single universal setting.
View page →Flat beer
Beer pouring flat
Flat pours can result from low pressure, gas loss, incorrect balance, warm product, excessive residence time or product-specific requirements.
View page →Temperature fault
Beer too cold or freezing
Overcooling can freeze product, restrict flow and create erratic pours. Glycol set points, circulation and line position should be checked.
View page →Cooling fault
Beer too warm at the tap
Warm beer can start with keg-room temperature, glycol capacity, pump circulation, python insulation, long idle periods or refrigeration failure.
View page →Gas fault
Beer system losing pressure
Pressure loss may come from gas supply, regulators, leaks, fittings, couplers or a system that has not been correctly balanced.
View page →Circulation fault
Glycol pump failure
A failed or weak glycol pump can leave remote fonts and product lines warm even when the chiller itself appears to be operating.
View page →Font cooling fault
Beer font not cooling
A warm font can indicate poor glycol circulation, air in the loop, insulation problems, a blocked path or inadequate system capacity.
