System TroubleShooting
Problem
What Could Be Wrong
How To Fix
The System motor will not
turn on.
NOTE: the float switch directly cuts power to the motor when the liquid gets low.
Use float jumper to diagnose any float issues.
Insecticide level is to low. Float is down
Refill insecticide reservoir.
Float switch (inside the reservoir) is
stuck in a downward position.
Release float from stuck
position. And/or shake float bulb
to see if it is possible internally
stuck
Digital timer makes a single
snapping noise when cycle
activates, but motor does
not run
The snapping means power is being
sent to the onboard relay, but not getting to the motor. The float is the only
interrupt in between the timer and the
motor.
Float could be stuck or float
could be defective. Use jumper
plug to diagnose. Possible replacement of float could be
needed.
Analog clock timer keeps
time, but does not operate
the System at preset times.
Manual button WORKS.
Possible 24 hour clock problem
Replacement of 24 hour clock
may be needed
Analog clock timer keeps
time, but does not operate
the System at preset times.
Manual button DOES NOT
work.
Possible internal interval/relay problem
Replacement of
may be needed
interval/relay
Analog timer runs continuously and will not shut off
unless unplugged
Possible internal relay contacts sticking
Replacement of
may be needed
interval/relay
Contacts in potentiometer (seconds
knob) are bad.
Replace potentiometer.
Problem
What Could Be Wrong
How To Fix
Digital timer does not keep
time or program in memory
when power is lost.
NOTE: Replace batteries
once per year.
On board AA batteries are low on
power/dead.
Remove front display panel to
access black AA battery case.
Replace AA batteries. Perform
“reset to defaults” Reprogram
timer.
Digital timer has odd reading on display, but works
via manual button (up).
On board AA batteries could be low on
power/dead or could need to perform
“reset to defaults”.
Replace AA batteries (see previous page) and/or perform “reset
to defaults”.
Digital timer has no display
reading, will not perform
any functions.
Display/logic board may be corroded or
malfunctioning.
Replace LCD/Logic board.
Digital timer has no display
reading, but programming
and manual functions work.
The display is LCD and has lost visibility under extreme heat.
Relocate system reservoir and
pumping unit to area out of direct sunlight or indoors (garage
or shed).
Digital timer will only activate via manual button (up)
or with remote control.
NOTE: a “reset to defaults”
can help to cure this if all
else fails.
Timer is in manual mode. LCD screen
reads “off”
Push the down keypad button so
LCD screen reads “on”.
Button on keypad could be defective or
keypad cable could be cracked.
Replace keypad.
Digital timer performs all
functions but remote control
does not work.
Battery in remote control is dead.
Open remote control and replace battery. Older remotes
will need to be reprogrammed to
the timer.
The System operates at
normal pressure, but
nozzles do not spray.
Nozzle tips may be clogged with
debris.
Clean or replace nozzle tips.
Filter water when filling to minimize clogging problems.
Tubing could be kinked not allowing
liquid to get to nozzles.
Unbend or unkink tubing.
Gauge could be defective and giving
an incorrect (lower) reading.
Replace gauge.
Inline filter could be clogged.
If system has an inline filter,
check to see if it is clogged and
needs cleaning. Filter should be
located in the outgoing feed line
after the pump.
Problem
The System operates, but
has low or no pressure.
The pump/motor surges
on - off, on - off.
The system is tripping a
circuit breaker.
What Could Be Wrong
How To Fix
Pump may be defective.
Unplug system. Remove pump
from motor, spin shaft on pumpwith fingers. Shaft should spin
freely, if tight, replace pump.
Needle valve fitting on pump is in an
outward position, bypassing liquid back
into reservoir..
Turn screw on needle valve fitting in, clockwise, until pressure
reads 170-180 psi on gauge.
Needle valve fitting on pump is defective and not allowing pressure to build.
Replace needle valve fitting on
pump
Suction filter (inside of reservoir) is
plugged with debris.
Remove suction filter, clean or
replace.
Air leak on the suction fitting (elbow)
on the pump.
Check fittings, secure tubing into
suction fitting making sure it is
properly seated.
Check valve before suction filter in reservoir is malfunctioning.
Remove check valve from tubing
and run system briefly to check.
Replace check valve.
Tubing has a leak, cut or break.
Look for leak, use union to slice
in or replace tubing.
Needle valve fitting on pump is
screwed in to far. Motor will heat up
from this and cause to thermally shut
off.
Turn screw on needle valve fitting out, counter-clockwise, until
pressure reads 170-180 psi on
gauge. If motor is hot and will
not run, let it cool down and the
thermal overload will reset.
The reservoir liquid may be low and
the return liquid is spraying onto the
black float bulb.
Reposition the return line so that
the liquid is not spraying onto
the black float bulb. Refill the
system.
.
The motor may be defective.

Unplug system. Remove pump
from motor, spin shaft of motor
with fingers. Shaft should spin
freely, if tight, replace motor.
And/or run motor without pump
attached to see if the motor runs
tough, makes noise or heat up.
Replace motor if any of these
symptoms occur.
