Problem
Possible Cause
Corrective Action
Inadequate circulation.
(For alert display

Filter or pump basket dirty.
Suction/discharge piping is too small.
Speed is set too slow for proper filtration cycle.
Check trap basket; if plugged, turn pump off and clean
basket.
Check and clean pool filter.
Increase piping size.
Increase filtration run time.
Electrical problem.
(For
alert display
messages, refer to Alerts
and Warning on page 23).
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 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 connections.
Motor internal terminal overload protector is open.

Check for proper impeller or impeller rubbing.
Mechanical Troubles
and Noise.
The pump motor is running but with loud noise.
Foreign matter (gravel, metal, etc.) in
pump impeller.
Cavitation.
If suction and discharge piping are not adequately
supported, pump assembly will be strained. Do not
mount pump on a wooden platform! Securely mount
on concrete platform for quietest performance.
Disassemble pump, clean impeller, follow pump ser-
vice instructions for reassembly.
Improve suction conditions.
Increase pipe size.
Decrease number of fittings.
Increase discharge pressure.
Pump does not respond
to IntelliTouch,
EasyTouch,
SunTouch, IntelliComm
system commands.
Improper automation setup.
Communication network inoperative.
1. Be sure that the communication cable is
connected at both ends.
2. Check that the pump local address matches with
the address used in the IntelliTouch control system.
3. Check that the pump has been assigned a circuit
name on the IntelliTouch control system.
4. Ensure that the 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
