Vortex pump not full or stroke not complete alarms.

To ensure an accurate mix ratio the Vortex™ precisely tracks the amount of water through the system and based off the desired mix ratio tells the pumps when to stroke. The Vortex™ monitors every pump stroke to verify the pump fills fully and completes a full dispense stroke, from this monitoring 2 potential alarms could occur:

1. Alarm “A10: PUMP NOT FULL” indicates that the pump is still drawing in concentrate and has not fully filled before needing to stroke again. This is done by monitoring the concentrate pressure.
2. Alarm “A11: STROKE NOT COMPLETE” indicates that the pump has not completed a full dispense stroke before needing to stroke again. This occurs when a prox sensor isn’t made when stroking the pump.

The most common cause of these alarms is that the Vortex™ cannot pump concentrate fast enough to keep up with the water flow rate at the desired mix ratio. In this case either the pump stroke speed should be increased, or the water flow rate should be decreased. When making these adjustments target a delay of 2 seconds between pump strokes (between 1 red light turning off and the other turning on). 

If adjusting the pump stroke speed or water flow rate does not resolve these alarms refer to the manual as there could be a faulty sensor or another failed component.
