Troubleshooting Guide
Solution
A
Turn the unit's power off and on,
adjust the settings, and attempt to
resume pumping.
B
1.
Use a multimeter to measure
the line voltage used by the
pump motor.
2.
Compare the voltage rating on
the unit's label (on the back of
the pump motor) with the line
voltage to make sure that you
are using the correct line
voltage. The pump motor
requires line voltages of 90
to 130 Vac (for 115 Vac units)
or 190 to 260 Vac (for
220 Vac units).
3.
If the line voltage is
inappropriate for the pump
motor; move it to another line
voltage source.
C
Check the pumping environment
for devices that could be creating
electrical noise. If possible, shut off
these devices or move the pump
motor to another location.
D
Turn the unit's power off and on,
adjusting the settings, and attempt to
resume pumping. If the problem
persists, call Customer Service.
