Diagnostic Fault Codes
Code Fault
F1
Motor Underload • Over-pumped well
• Broken shaft or coupling
• Blocked screen, worn pump
• Air/gas locked pump
• SubDrive not set properly for pump end
• Underload Sensitivity setting incorrect
• Drive is in thermal foldback
F2 Undervoltage • Low line voltage
• Miswired input leads
• Loose connection at breaker or panel
F3
Overcurrent or • Motor and/or pump misalignment
Locked Pump
• Dragging motor and/or pump
• Motor and/or pump locked
• Abrasives in pump
• Excess motor cable length
F4
Incorrectly Wired • Input and output wires are swapped
F5 Output Open • Loose connection
Phase
• Defective motor or drop cable
• Wrong motor
F6
Short Circuit • When fault is indicated immediately after
power-up, short circuit caused by a shorted
connection, defective cable, splice, or motor
F7
Overheated Drive • High ambient temperature
• Direct sunlight
• Obstruction of airflow channel
F8
Over Pressure • Measured pressure exceeds setting
F9
Internal PCB Fault • A fault was found internal to drive
F12
Overvoltage • High line voltage
• Internal voltage too high

Possible Cause Corrective Action
• Frequency near maximum with load less than configured underload sensitivity
(SubDrive Connect Plus mobile app)
• System is drawing down to pump inlet (out of water)
• High static, light loading pump - reset Underload Sensitivity setting (in the
programming menu and mobile app) if not out of water
• Check pump rotation, reconnect if necessary for proper rotation
• Air/gas locked pump - if possible, set deeper in well to reduce
• Verify MAX AMPS setting (in the programming menu and mobile app) is correct.
For MagForce application, make sure MAX AMPS matches pump load's rated
current.
• If the drive is in thermal foldback, see corrective actions for fault code F7.
• Line voltage low, less than approximately:
- 155 VAC (normal 230 operating range = 190 to 260)
- 290 VAC (normal 460 operating range = 380 to 520)
• Check incoming power connections and correct or tighten if necessary
• Correct incoming voltage - check breaker or fuses, contact power company
• Amperage is above MAX AMPS at minimum frequency
• Remove and repair or replace as required
• Reduce motor cable length. Adhere to Maximum Motor Cable Length table.
• For FE MagForce application, verify motor model selection, pump load, and max
amps.
• Check wiring, check motor size, adjust or repair as needed.
• Open reading on DC test at start.
• Check drop cable and motor resistance, tighten output connections, repair or
replace as necessary.
• Use dry motor to check drive functions. If drive runs and exhibits an underload
fault, drive is good.
• Amperage exceeded 25 amps on DC test at start or SF amps during running
• Incorrect output wiring, phase to phase short, phase to ground short in wiring or
motor
• If fault is present after resetting and removing motor leads, replace drive
• The drive has exceeded max rated temperature, needs to drop below 167 °F (75
°C) to restart
• Fans blocked or inoperable, ambient above 104 °F (40 °C), direct sunlight, air flow
channel blocked
• Replace fans or fan module; or relocate drive as necessary
• Remove debris from fan intake/exhaust
• Troubleshoot system to locate reason for high pressure
• Contact your Franklin Electric Service Personnel
• Unit may require replacement. If problem persists, note the sub-fault number on
the display before contacting the FE Service Personnel.
• Line voltage high, greater than approximately:
- 290 VAC (normal 230 operating range = 190 to 260)
- 600 VAC (normal 460 operating range = 380 to 520)
• Check incoming power connections and correct or tighten terminals if necessary
• If line voltage is stable and measured below 260 VAC and problem persists,
contact your Franklin Electric Service Personnel.
