Possible Cause Checks Corrective Action
No AC power switched
through starter relay (if
applicable). Using an AC voltmeter,
measure the output contacts
of the starter relay. Is 115
(230) VAC measured?
Is the breaker which supplies
power to the submersible
pump through the starter relay
off or tripped?
Is 115 (230) VAC being
switched through the
submersible power feed
breaker?
Is 115 (230) VAC measured at
the input contacts of the starter
relay?
Replace the starter relay if 115
(230) VAC is not measured at
the output contacts of the
starter relay but is measured
at the input contacts.
Turn breaker on, if off.
Replace breaker if 115 (230)
VAC is not being switched.
Repair wiring problems if 115
(230) VAC is not measured at
starter relay input contacts.
No AC power to submersible
motor. If no starter relay, use an AC
voltmeter to measure between
neutral and the output of the A
contacts of the pump power
terminal block in the Series
1000 post. Is 115 VAC
measured?
If no starter relay, use an AC
voltmeter to measure the
electric reset submersible
drive in the AC junction box.
Is 115VAC measured?
Using an AC voltmeter,
measure the input to the
submersible motor. Is 115
(230) VAC measured?
Replace the pump override
switch if 115 VAC is not
measured at the output of the
pump power terminal block,
but is measured at the input.
Repair or replace the electric
reset if 115VAC is not
measured at the submersible
drive output.
If no starter relay and 115
(230) VAC is not measured,
repair wiring from electric reset
to submersible motor. If using
a starter relay and 115 (230)
VAC is not measured, repair
wiring from starter relay to
submersible motor.
Defective submersible motor. Call qualified service
personnel.
