The SUB is equipped with a pump inside that helps to keep the mini-keg under pressure, so don’t be alarmed when the noise comes on as soon as you begin to pour. The sound will go away after a few seconds.
If you feel that the noise is excessive try the trouble-shooting tactics below.
- Try a different outlet
- Wait at least 1 hour after inserting a mini-keg
- Unplug the SUB for 1 hour and then plug in again
If none of these steps work, please contact us using our support form and, if possible, include a video of your SUB malfunctioning.
