There are many reasons as to why you may be experiencing fobbing beer. Please try these basic tests first:
◉ Pressure - A common cause (especially with external gas bottles) is having too little or too much pressure in the keg. With the built in air compressors, all you need to ensure if the air compressor switch on the back of the unit is on and the keg will be at the correct pressure. If you’re using Co2 gas, ensure your pressure is set to around 23 PSI and mixed gas around 35 PSI.
◉ Gas Leak - If you have a gas leak in your lines or coupler, the pressure in the keg may drop resulting in the beer fobbing. The best way to test for a gas leak is to fill a spray bottle with water and some detergent then spray over the gas line. If you see bubbles forming at any point on the line there may be a leak in that area.
◉ Cooler - If your cooler isn’t turned on enough, you may find the beer fobs slightly.
It is very rare, however if it is none of the above, it can be the keg itself that is very foamy. If it is a keykeg you are using, you can try the below as a last attempt:
If your KeyKeg is excessively ‘fobby’ one potential solution is to ‘vent’ the keg. This is a essentially method of releasing excess pressure that may have built up in the keg due to excess fermentation or the beer being over-carbonated at time of packaging at the brewery.
Try the following steps for venting:
◉ Turn off your dispenser unit
◉ Use the pull ring on the keykeg coupler to release gas from the keg.
◉ Pull down the beer tap to let all the excess gas get released(you will lose a bit of beer here unfortunately).
◉ Leave the beer tap open for at least 2 hours. You should see big bubbles of beer coming out - that's a good sign!
◉ After 2 hours turn the beer tap off, turn the Lindr back on, then try to serve again
