Troubleshooting Tips

It is unusual for one of these units to fail during the warranty period. Typically if a JED Model 203 or 603 fails within the first year of use, something has blocked the airflow. Having the air stone positioned deeper than 4 feet below the surface of the water can also cause an issue. If the water inside the tank is deeper than 4 feet, you may devise a float in order to keep the air stone suspended at no more that 4 feet beneath the surface of the water. This allows the air stone to move up and down with changes to the water level without allowing it to fall deeper than 4 feet. Other possibilities that can block airflow would include a clogged air stone, kinked air hose, or the tubing getting pulled/yanked out of the corona discharge assembly—even only slightly. This causes ozone to fill the enclosure and destroy the unit. In some cases, a lightning strike can take out the transformer, and while the air pump might still work, it may no longer produce ozone.
