Section 9
General
The AquaBoost II is a self-diagnosing controller. If a problem occurs, observe the Status Code Indicator Light on
the front of the unit. No Status Code Indicator Light means either no or low input voltage (less than 50 V).
Danger
Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch
DANGER
Hazardous and circuit breaker and wait 5 minutes before servicing. High voltage may still remain on

controller.
Refer to the status code label on the side of the controller access cover to diagnose system errors.
See Diagram 6 for details.
Use the following table to help troubleshoot problems.

Green Light Codes
Description
Constant Green Light indicates the pump is off. The system is in
Standby mode when there is no flow in the system and the pressure
setting has been reached. The system is in a Low Voltage condition
when the line input voltage drops below 196VAC.
Flashing Green Light indicates the pump is running. If pump is not
running, turn off power to controller and wait 5 minutes. Check
output power connections from controller to motor.
Red Light Codes
Replace AquaBoost II Controller
This fault is indicated if system pressure drops below 10 PSI for more
than 20 seconds. The system will automatically restart after 5 minutes.
If 10 faults occur in an hour, the system will not restart and needs to
be manually reset. If problem reoccurs, please verify well capacity and/
or pump capacity.
This fault is indicated if there is a drastic drop in system pressure in a
short amount of time. The pump will continue to run. This can be
caused by low air pressure in the tank or the tank bladder may have
failed. This can also be caused by extreme changes in flow. The error
is cleared each time the pump starts. If the error reoccurs often, check
the air pressure in the tank. Before checking tank air pressure, turn
power to control off to prevent pump from turning on. Relieve
system pressure by opening a faucet. The tank pre-charge may be set
anywhere between the factory preset 18 PSI and 10 PSI below the
pressure setting.
