Possible Cause Checks Corrective Action
Out of fuel. Stick the tank to verify level of
fuel. Order fuel if tank is empty.
Leak detector did not open. Leak in supply line or piping. Replace defective leak
detector if it does not open.
Call qualified service
personnel.
Shear valve tripped. Is valve tripped? Check for
what caused it to trip (loose
mounting to island, cabinet
had been hit, etc.) Reset, or if necessary, replace
shear valve if it is tripped.
Correct cause of tripping.
No AC power to solenoid
valve. Using an AC voltmeter,
measure across the solenoid
after reset is complete. Is
115VAC measured? Repair or replace the electric
reset if 115 VAC is not
measured at solenoid.
Defective solenoid valve. Check if solenoid valve clicks
open when 115VAC is applied. Replace the solenoid valve if it
does not click open when
115VAC is applied.
No AC power to starter relay (if
applicable). Using an AC voltmeter,
measure between neutral and
the output of the A contacts of
the pump power terminal
block. Is 115VAC measured?
Using an AC voltmeter, in the
AC junction box, measure the
electric reset submersible
drive output. Is 115VAC
measured?
Using an AC voltmeter,
measure across the starter
relay coil. Is 115VAC
measured?
Replace the pump override
switch if 115VAC 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.
Repair wiring from electric
reset to starter relay if 115VAC
is not measured across relay
coil.
Defective starter relay (if
applicable). Does starter relay close when
115 VAC is applied? Replace starter relay if it does
not close when 115VAC is
applied.
