Possible Cause Checks Corrective Action
Defective electric reset or
defective solenoid valve(s). Turn the pump handle on.
After reset has completed,
check if 115 (230) VAC is
measured at the SUBM
DRIVE and the solenoid(s) in
the dispenser junction box. If 115 (230) VAC is not
measured on the SUBM
DRIVE and the solenoid(s),
repair or replace the electric
reset.
If 115 (230) VAC is measured
on the SUBM DRIVE, go to
"No AC power at submersible
starter relay coil" if starter
relay is used; or "No AC
power at submersible pump
motor", if no starter relay is
used.
If 115VAC is measured at the
solenoid valve(s) but it
doesn't click open, replace
the valve(s).
No AC power at submersible
starter relay coil (if used). Measure across the
submersible starter relay coil
contacts. Repair the wiring between the
dispenser junction box and
the submersible starter relay
if 115VAC is not measured.
Defective submersible starter
relay (if used). Check if the submersible
starter relay closes when
115VAC is across the coil
contacts. Replace the submersible
starter relay if it does not
close when 115VAC is
measured across the coil
contacts.
