Q: My pump’s driver is blinking red, what should I do?
A: The most common cause of a VorTech pump driver blinking red is because the auto-disconnect calibration was performed improperly. In order to enable disconnect auto-shutoff protection, you must perform a calibration step. This procedure is outlined in the instruction manual. An important aspect of this procedure is that the dry side of the VorTech pump must go through the calibration sequence while holding it in your hand. If you leave the pump attached to the aquarium during this calibration process, it will result in blinking red errors that will remain until the calibration is cleared from the pump’s memory. To clear the calibration, you must perform the following steps:
Hold mode (pump blinks white)
Hold mode and set (pump blinks yellow/white)
Cycle power to the pump by un-plugging and re-plugging it in
Upon re-powering, the pump should operate normally. If you would like to re-enable calibration properly, remove the dry side from the aquarium, hold it in your hand, and follow the directions for enabling pump disconnect auto-shutoff protection in your user manual.
