Why does my Goulds Controller show F04 Over Current error?
- C
  Christina Jones MDAug 19, 2025
  The F04 error on a Goulds Controller indicates an overcurrent situation. This can be due to: * Using the wrong motor (incorrect voltage or phase). * Mechanical binding from debris in the pump. * Electrical or mechanical failure of the motor. * Incorrect setting of the “MOTOR OVERLOAD SETTING (SFA)” switch. If the controller detects three overcurrent faults, manually reset it by turning the power off for one minute, and then back on.

What to do if my Goulds Aquavar Solo 2 Controller shows F03 Sensor Fault?
- J
  joshua18Aug 22, 2025
  The F03 error on your Goulds Controller indicates a sensor fault. This can be caused by: * A disconnected sensor. * A disconnected sensor cable lead inside the controller. * A broken wire in the sensor cable. * A miswired sensor cable. * A failed sensor. To troubleshoot, ensure the sensor is properly connected. With the sensor cable connected to the circuit board, measure the DC voltage between the black and white wires of the sensor cable at the sensor connector. The voltage measured should be between 0.5Vdc and 4.5Vdc depending on the system pressure.

How to fix Goulds Aquavar Solo 2 Controller F05 Short Circuit error?
- J
  janet62Aug 26, 2025
  The F05 error on a Goulds Controller indicates a short circuit. This can be caused by: * Electrical failure of the motor. * Electrical failure of wiring between controller and motor. To address this, first, turn the power off for one minute and then back on to verify the error. If the error persists, the motor and wiring between the controller and motor must be checked. Turn the power off for 5 minutes, remove the motor wires from the output terminal block, and check the wiring and motor for shorting phase to phase and phase to ground.

What causes F06 Ground Fault on my Goulds Aquavar Solo 2 Controller?
- R
  ryan07Aug 28, 2025
  The F06 error on your Goulds Controller indicates a ground fault. This can be caused by: * Electrical failure of the motor. * Electrical failure of wiring between controller and motor. * Miswiring of motor cable. To troubleshoot, verify the error by turning the power to the controller off for one minute and then back on. If the error persists, the motor and wiring between the controller and motor must be checked.

How to troubleshoot a Goulds Aquavar Solo 2 with no light?
- J
  james13Aug 31, 2025
  If there is no light on your Goulds Controller, it may be due to low or no input voltage. Check the input voltage to the controller using an AC Voltmeter between L1 and L2. The voltage should be greater than 190Vac.

Why does my Goulds Aquavar Solo 2 Controller display F07 Temperature error?
- B
  Brandi HughesSep 3, 2025
  The F07 error on a Goulds Controller indicates a temperature issue. This can be caused by: * High ambient temperature (above 122º F or 50º C). * Low ambient temperature (below -4º F or -20º C). * Fan failure. Ensure the fan is not obstructed or clogged.

What does F08 Open Lead mean on my Goulds Aquavar Solo 2?
- S
  Susan DiazSep 6, 2025
  The F08 error on a Goulds Controller indicates an open lead. This can be caused by a disconnected or broken wire between the controller and motor. To resolve this, verify the error by turning the power to the controller off for one minute and then back on. If the error persists, the motor and wiring between the controller and motor must be checked.

What causes F09 Low Pressure Cut-Off on my Goulds Aquavar Solo 2 Controller?
- O
  omullenSep 9, 2025
  The F09 error on a Goulds Controller indicates a low-pressure cut-off. This occurs when the pressure is 20 PSI below the set point for 30 seconds, possibly due to a broken pipe or a tripped pressure relief valve. If a 20 PSI or more pressure drop for 30 seconds is normal for the system, switch the Low Pressure Cut-Off protection off or change the system to prevent the pressure drop.

How to remove Goulds Aquavar Solo 2 from Program Mode (PrOG)?
- A
  Anthony BowmanSep 12, 2025
  The 'PrOG' indication on the Goulds Controller means it is set to programming mode. This happens when the Programming Position pins on the upper-left corner of the UIB are connected at power up. To exit Program Mode, disconnect the jumper or connection linking the Programming Position pins, turn off the controller, wait one minute, and then turn it back on.

What to do if my Goulds Aquavar Solo 2 shows F02 Dry Well No Water/Loss of Prime error?
- D
  David LeNov 15, 2025
  The F02 error on your Goulds Controller, indicating a dry well, no water, or loss of prime, can occur for several reasons: * The water supply level in the well might be below the pump's suction inlet. * The suction screen could be plugged. * There might be a restriction in the pipe between the pump and the pressure sensor. * The pump might be air-bound. * The “MAXIMUM SPEED” switch might be set incorrectly (ensure it’s at 80 Hz for mismatched pumps and motors). * The “MOTOR OVERLOAD SETTING (SFA)” switch might be set too high (it should not exceed the motor's Service Factor Amps). To address this, ensure an adequate water supply. If the issue persists, try the following: * Set the Dry Well Sensitivity switch to HIGH. * Measure the maximum output current and set the MOTOR...
