An airlock is a common occurrence for any hot tub owner, so don&#x2019;t be alarmed if you run into this with your AV-2! An airlock is very easy to identify and fortunately, very easy to resolve as well.Use the video below, as well as the instructions that follow, to guide you through identifying and fixing an airlock problem. <iframe width="632" height="355" src="https://www.youtube.com/embed/kQF4GNApbBo" title="Troubleshooting: How to resolve an airlock on your Aquavoss Model 2 (hot tub side)" frameborder="0" allowfullscreen class="fr-draggable">&#xA0;</iframe>&#xA0;IDENTIFYING AN AIRLOCK IN YOUR HOT TUBThere are two ways to determine if there&#x2019;s an airlock in your hot tub:First, when you power on your hot tub, the unit will enter priming mode. You&#x2019;ll hear the circulation pump start. However, you won&#x2019;t see any water circulating through the hot tub. Normally, you would see bubbles appear in the middle of the hot tub when there is proper circulation.Second, the control panel will display OHH for overheating or DRY after approximately 5 minutes, indicating a lack of water flow.RESOLVING AN AIRLOCKNow that you&#x2019;ve identified that your hot tub indeed has an airlock, here are the steps to address this problem:1. Turn off the system:&#xA0;Find your subpanel where your GFCI breaker is located and turn the breaker to the &#x201C;OFF&#x201D; position.2. Remove the front access panel: Take off the front access panel to access the internal components.3. Locate the water union: Find the water union that connects the pump to the control system.<img width="624" height="280" src="https://attachments.gorgias.help/0eMnwxKwWRVx9bDN/hc/zKB3oxwjaDW7rkVO/2026020620-6d25981d-a155-4e30-86ee-c8cc1ac015a0-d7c44441-3129-436d-ba75-201ec53542a3.png" class="fr-fic fr-dii">&#xA0;4. Release air from the water union: Loosen the water union by turning it counter clockwise until you hear a hissing sound. This hissing sound indicates that the trapped air has been released. Continue to twist until you visibly see water coming out of the union. Very important: place a bowl underneath the union when you do this so that when the water spills, it does not spill onto the pump underneath it.5. Turn on the system: Return to your subpanel where your GFCI breaker is located and turn the breaker to the &#x201C;ON&#x201D; position.6.
