Beer is not pouring or not pouring well

Problem	Possible Cause & Solution
Pouring too quickly	Beer Line may be too short. Please refer to this chart for a guide to recommended lengths for beer line of various diameter
	CO2 pressure may be too high. Most short draw kegerator systems and beers are served at approx. 10-12psi. Please refer to this Carbonation Chart for more info
	Beer may be over-carbonated. The keg will need to be de-carbonated by reducing excess CO2 pressure. Refer to this guide to fix over-carbonated beer
Pouring too slowly	CO2 pressure may be too low. Most short draw kegerator systems and beers are served at approx. 10-12psi. Please refer to this Carbonation Chart for more info
	Beer Line may be too long. Please refer to this chart for a guide to recommended lengths for beer line of various diameter
	Beer may not be fully carbonated. Leave the keg hooked up to CO2 until full carbonation is achieved.
Beer is too foamy/frothy	Beer may be over-carbonated. The keg will need to be de-carbonated by reducing excess CO2 pressure. Typically most beers in a short draw system are served at approx. 10-12psi. Refer to this guide to fix over-carbonated beer
	Beer Line may be too short. Please refer to this chart for a guide to recommended lengths for beer line of various diameter
	The beer lines may be frozen. If the beer line comes in contact with the cold plate in the fridge it can partially freeze the beer in the line. This creates turbulence in the line which can cause excess foam. Ensure the beer lines are not in contact with the cold plate.
	Beer may be too warm. Increase the Set Point of the kegerator or leave the keg in the kegerator until it is fully chilled
Beer does not have enough head	Beer may not be fully carbonated. Leave the keg hooked up to CO2 until full carbonation is achieved. Please refer to this Carbonation Chart for more info
	Beer Line may be too long. Please refer to this chart for a guide to recommended lengths for beer line of various diameter
	Beer may be too cold. Increase the Set Point of the kegerator
	(Homebrew) Beer may not have much head. Not all beer styles produce a lot of head - this may be due to the grist of the particular brew or possibly a brewing technique affected the head
No beer comes out of tap	Lines or connections may be blocked. If the beer contains a lot of hop matter there could be hop matter stuck in the liquid dip tube or liquid post of the keg. To fix this, release the pressure in the keg by pulling on the PRV. Remove the liquid post with a socket or spanner. Remove the liquid dip tube and ensure no hop matter is blocking the dip tube or the post
	The beer lines may be frozen. If the beer line comes in contact with the cold plate in the fridge it can freeze the beer in the line and partially or completely block the flow. Ensure the lines do not come into contact with the cold plate
	CO2 cylinder may be empty. If there is insufficient CO2 to pressurise the head space of the keg then beer will not pour. Replace or refill the CO2 cylinder if empty
	Keg may be frozen. If the Set Point is too low or there is an issue with the temp probe calibration, the keg(s) may freeze. Check and correct the calibration and Set Point of the kegerator
Beer is too warm	Kegerator may not be cold enough. Check and adjust the Set Point of the kegerator. 2°C is typically the correct temperature to achieve a good pour
	Keg may not be cold enough. Leave the keg in the kegerator until it is fully chilled. This can take up to 24 hours (for example) with a room temperature 50L keg
	Kegerator may need calibrating. Check the actual internal temperature of the kegerator. If this is much higher than the indicated temperature then perform Offset Calibration to ensure the correct temperature is maintained
	Font not cool enough. Direct the Font Fan tubing to the top of the font. Cut the Font Fan tubing to the correct length. Cut the tubing at a 45° angle to ensure it remains unobstructed. Ensure the fan is turned on

Gas Issues & Gas Leaks

Problem	Possible Cause & Solution
CO2 Cylinder is empty	Cylinder may be used up. It takes approx 6g of CO2 to dispense 1L of beer at normal serving pressure. Thus, a 2.6kg CO2 cylinder will dispense approx. 8 x 50L kegs. More CO2 will be used if also carbonating the kegs. Refill the CO2 cylinder when empty
	Possible Gas Leak. Perform an Isolation Test to check for potential CO2 leaks

Kegerator cooling issues

Problem	Possible Cause and Solution
Kegerator not cooling to set point temperature	Set Point may be too high. Check and adjust the Set Point of the kegerator. 2°C is typically the correct temperature to achieve a good pour
	Ice build up. If there is visible ice build up on the cold plate this will act as an insulator and prevent the cavity of the kegerator from cooling properly. Defrost the kegerator by turning it off until the ice has melted. Note: Do not try to remove the ice physically as this may damage the refrigerant lines and is not covered under warranty
	Front vents may be covered. The UnderCover kegerator is designed to be built into a typical 600mm cabinet and thus does not require celarance at the sides or rear. The front vents require ventilation. Ensure that these are not covered or cooling performance and warranty may be affected
	Door left open/not closed properly. If the door is not properly closed or misaligned the kegerator may not cool adequately. Ensure the door is closed and aligned properly
	Not calibrated properly. If the kegerator is not cooling adequately but the compressor is cycling at the Set Point temperature the kegerator may require Calibration.
	Hot environment. If you are in a very hot environment remove the font tube from the font tower and instead direct it into the kegerator to improve air flow throughout the fridge. This is because of ‘heat ingress’ into the system
Kegerator is too cold	Kegerator may need calibrating. Check the actual internal temperature of the kegerator. If this is much higher than the indicated temperature then perform Offset Calibration to ensure the correct temperature is maintained
	Set Point temperature may be incorrect. Check the Set Point temperature. For best results set this to 2°C. Setting too low a temperature may cause freezing or performance issues

General Troubleshooting

Problem	Possible Cause & Solution
How to adjust Set Point Temperature	Press the Up or Down buttons to select the desired et Point. Press the SET button to save the Set Point
Excessive noise from fan	Ice build up. If there is visible ice build up there is likely also ice in the fan housing. The fan lades will hit this when spinning causing excessive noise. Defrost the kegerator by turning it off until the ice has melted. Note: Do not try to remove the ice physically as this may damage the refrigerant lines and is not covered under warranty
	Loose wiring. It is possible for the lead to the fan to become slightly loose and contact the blades causing noise. Remove the fan housing and reposition the wire to prevent it from contacting the blades
Ice build up on cold plate	Moisture or humidity ingress. If the door is left open or the seals are damaged or dirty then ice can build up on the cold plate. If there is visible ice build up on the cold plate this will act as an insulator and prevent the cavity of the kegerator from cooling properly. Defrost the kegerator by turning it off until the ice has melted. Once defrosted, locate and correct the source of moisture ingress. Note: Do not try to remove the ice physically as this may damage the refrigerant lines and is not covered under warranty
EE Error	This is an electrical fault. This can be caused by a faulty Temperature Probe (Thermistor) or a loose connection or damaged or faulty connection. Try replacing the Temperature Probe. Inspect the board for loose or damaged connections
Water is leaking from kegerator	Melted ice build up. If there is too much water, moisture or humidity ingress in the kegerator, the ice build up can overwhelm the evaporator plate at the rear of the kegerator. Defrost the kegerator (if necessary) by turning it off until the ice has melted. Once defrosted, locate and correct the source of moisture ingress. Note: Do not try to remove the ice physically as this may damage the refrigerant lines and is not covered under warranty

How To Fix An Over Carbonated Keg

If your beer is foaming after checking CO2 pressure, beer line length and kegerator temperature, then possibly the beer is over-carbonated. If this is the gas, then the carbonation level of the beer in the keg will need to be reduced in order to get a good pour.

19L Corny Keg

19L Cornelius Kegs have a PRV (Pressure Relief Valve) which makes releasing excess pressure quite easy. TO fix an over-carbonated 19L keg (or any homebrew keg with a PRV such as a 20L OXEBAR keg) follow these steps:

1. Disconnect the gas line to the keg

2. Pull the PRV to vent all headspace pressure

3. Wait a couple of hours and then repeat. DO not reconnect the gas line until the desired carbonation level has dropped

This process can be sped up if the keg is removed from the kegerator and allowed to come to room temperature - CO2 will come out of solution faster at room temperatures. You can also vent the PRV, then close the PRV and shake the keg for 30 seconds, then vent it again. This will help force CO2 out of solution. Please note that this can cause beer or foam to spray from the PRV when venting, so proceed with caution.

Commercial Keg

Commercial kegs such as 20L, 30L or 50L kegs which are connected to the beer and gas lines by a coupler do not have a PRV, so it is a bit trickier to vent excess carbonation.

If the beer is only slightly over carbonated, the easiest way to reduce carbonation is to turn off the CO2 cylinder valve and pour beer as normal. CO2 will come out of solution as the headspace pressure is purged. This will take a while however, depending on the level of over-carbonation.

To speed this up, remove the keg from the kegerator to allow it to come to room temperature. CO2 will come out of solution faster when the beer is warm.

Carbonation Chart

This chart is an easy way to determine the required CO2 pressure to achieve the desired carbonation level. As a general rule, setting the kegerator to 2°C and the reguator to 12psi will suit almost all beer styles
