Check voltage at motor terminals and
at panel while pump is running. If low,
see wiring instructions or consult power
company.
Check for loose connections.
Check line voltage; if less than 90% or
more than 110% of rated voltage, consult
a licensed electrician.
Increase ventilation.
Reduce ambient temperature.
Tighten any loose wiring connection.
Motor runs too hot. Turn power to motor
off.
Check for proper voltage.
Check for proper impeller or impeller
rubbing.
Control panel LCD
screen displays
sporadically or
flickers on/off.

performance.
Disassemble pump, clean impeller,
follow pump service instructions for
reassembly.
Improve suction conditions.
Decrease number of fittings.
Increase discharge pressure.
Inspect motor slinger and motor shaft
seal behind the slinger (NOT the pump’s
mechanical seal). Apply lubrication to the
motor shaft rubber seals.
Pump does
