Why is my Koralia Evolution running in reverse?
There are several possible causes of reversal in the Koralia Evolution.
- The bushing that sits inside the black wing of the impeller may have slipped down. If this has occured, simply push the bushing back into place. You can also contact Hydor USA Customer Service and request an upgraded bushing that snaps into place, preventing slippage.
- The front cover maybe damaged. If your cover is damaged, you can contact Hydor USA Customer Service and request a new cover.
- The rubber bumper on the inside of the front cover maybe missing or damaged. Hydor USA Customer Service can supply you with replacement parts.
If you cannot diagnose the cause on your own, feel free to contact Hydor USA Customer Service for assistance.
