Troubleshooting Problems
(Continued)
Problem
Possible Cause
Corrective Action
Pump trips and restarts
constantly
Air in system
Suction lift above design limits
Blocked suction/
Blocked discharge
System flow too high. System changing flow
too quickly.
In floor cleaning system issues.
Priming not enabled.
Issues related to other equipment, such
as, Heat Pumps and Heaters with internal
valves that vibrate.
Bleed air from filter. Ensure that air bubbles are not visible
coming into pump pot.
Insert vacuum gauge into pump port connection port.
Confirm vacuum level is 25 in. mercury (hg) or less.
Stop pump and clear blockage.
Reduce system flow. Change speed.
Reduce water flow. In floor cleaning systems must be
designed with balanced hydraulic losses on all legs.
Enable priming from the “PRIMING” menu.
Lowering ramp speed below 200 RPM may resolve the
issue or addition of external manual valve controls, may
resolve issue.
Inadequate circulation.
(For IntelliFlo pump alert display
messages, refer to Alerts and
Warning on page 43).
Clean debris from pump strainer
basket.
Speed is set too slow for proper
filtration cycle.
Check trap basket; if plugged, turn pump off and
clean basket. Suction/discharge piping is too small.
Check and clean pool filter.
Increase filtration run time
Electrical problem.
(For IntelliFlo pump alert display
messages, refer to Alerts and
Warning on page 43).
Could appear as a “Low Voltage” alarm.
PRIME ERROR may be displayed.
Could appear as “Over Heat” alert.
PRIME ERROR may be displayed.
Check voltage at motor terminals and at meter 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 connections.
Motor internal terminal overload protector is open.
Motor runs too hot. Turn power to motor off.
Check for proper voltage.
Check for proper impeller or impeller rubbing.
IntelliFlo pump does not
respond to IntelliTouch,
EasyTouch, SunTouch,
IntelliComm system commands
Improper automation IntelliFlo pump
setup.
Communication network inoperative.
1. Ensure that the communication cable is
connected at both ends.
2. Check that the IntelliFlo pump local address
matches with the address used in the IntelliTouch
system.
3. Check that the IntelliFlo pump has been assigned
a circuit name on the IntelliTouch system.
4. Ensure that the IntelliFlo pump display says
“DISPLAY NOT ACTIVE”.
A defective device on the network can inhibit the
proper operation of other network device. Devices
should be disconnected sequentially until the
network starts working.
