TROUBLESHOOTING
QUICK REFERENCE GUIDE
DIAGNOSTIC F
AUL
T CODES
Power down, disconnect leads to the motor and power up the SubDrive:
- If the SubDrive does not give an “open phase” fault (F5), then ther
e is a pr
oblem with the SubDrive.
- Connect the SubDrive to a dry motor
. If the motor goes thr
ough DC test and gives “underload” fault (F1), the SubDrive is working pr
operly
.

POSSIBLE CAUSE
CORRECTIVE ACTION
F1
MOTOR UNDERLOAD
- Overpumped well - Br
oken shaft or coupling
- Blocked scr
een, wor
n pump
- Air/gas locked pump - SubDrive not set pr
operly for pump end
- Underload Sensitivity setting incorr
ect
- Fr
equency near maximum with load less than configur
ed underload sensitivity (Potentiometer or Wi-Fi)
- System is drawing down to pump inlet (out of water) - High static, light loading pump - r
eset Potentiometer for less sensitivity if not out of water
- Check pump r
otation (SubDrive only) r
econnect if necessary for pr
oper r
otation
- Air/gas locked pump - if possible, set deeper in well to r
educe
- V
erify DIP switches ar
e set pr
operly
- Check Underload Sensitivity Setting (Potentiometer or Wi-Fi setting, whichever is applicable)
F2
UNDER
VOL
TAGE
- Low line voltage - Misconnected input leads - Loose connection at br
eaker or panel
- Line voltage low
, less than appr
oximately 150 V
AC (normal operating range = 190 to 260 V
AC)
- Check incoming power connections and corr
ect or tighten if necessary
- Corr
ect incoming voltage - check cir
cuit br
eaker or fuses, contact power company
F3
OVERCURRENT / LOCKED
PUMP
- Motor and/or pump misalignment - Dragging motor and/or pump - Motor and/or pump locked - Abrasives in pump - Excess motor cable length
-
Amperage above SFL at 30 Hz
-
Remove and r
epair or r
eplace as r
equir
ed
- Reduce motor cable length. Adher
e to Maximum Motor Cable Length table.

use “dry” motor to check drive functions. If drive will not run and exhibits underload fault r
eplace drive
F6
SHOR
T CIRCUIT
-
When fault is indicated immediately after power
-up, short cir
cuit
due to loose connection, defective cable, splice or motor
-
Amperage exceeded 25 amps on DC test at start or SF amps during running
-
Incorr
ect output wiring, phase to phase short, phase to gr
ound short in wiring or motor
-
If fault is pr
esent after r
esetting and r
emoving motor leads, r
eplace drive

F12
OVER
VOL
TAGE
- High line voltage - Inter
nal voltage too high
- Line voltage high - Check incoming power connections and corr
ect or tighten if necessary
- If line voltage is stable and measur
ed below 260 V
AC and pr
oblem persists, contact your
Franklin Electric Service Personnel
F14
BROKEN PIPE
- Br
oken pipe or lar
ge leak is detected in the system
- Drive runs at full power for 10 minutes without r
eaching pr
essur
e setpoint
- Lar
ge water draw
, such as a sprinkler system, does not allow system to r
each
pr
essur
e setpoint
- Check system for lar
ge leak or br
oken pipe
- If the system contains a sprinkler system or is being used to fill a pool or cister
n, disable the Br
oken Pipe Detection
