Tools & Parts
This Trouble Shooting Manual has been designed for easy simple step-by-step problem solving and fault isolation.
It is important to identify all of the possible causes of the problem before making a final diagnosis. What you see at first
is usually a symptom of the problem, not necessarily the problem itself.
Read the entire trouble shooting procedure related to what you are testing for prior to performing the test. This will give
you a clearer overall view and help to avoid a misdiagnosis.
Tools Required · Phillips & flat screwdriver
· Pliers
· 11/32” nut driver
· ¼” open end wrench
· 3/8” open end wrench
· Jumper cable
· Multi-meter and clamp-on Ammeter
· Accurate thermometer
· GFCI tester (optional)
Parts Required · Spaside control
· Temperature sensor
· Hi-Limit sensor
· 30A Fuse
· System Board
Pre-Test Prior to the service call, have the
homeowner check the following:
· Make sure spa is filled to the water
level recommended.
· Insure that all water shut off valves
are open and not vibrating closed.
· Assure that there is no obstruction
to the pump suction fittings.
· Adjust diverter valves and/or jets to
allow adequate back pressure to
heater assembly.
· If an FLO error is reported: Remove
the filter and operate the system. If
the error goes away, a filter
cleaning is required. Let the
customer know that the filter may
never look dirty, we are dealing with
oils, lotions etc… Use an
appropriate filter-cleaning agent.
· Get all of the information required
off of the data label.

Pressure or Flow Switch Not Activated
If 3 flashing dots appear below the temperature display, the printed circuit board must be checked to see if the LED
error indicator is illuminated. If it is not the 3 flashing dots are related to a problem with the pressure or flow switch. If
the system does not detect any pressure when the pump is manually or automatically turned on, 3 flashing dots will
appear below the temperature display.
Note that there must be enough water in the spa for it to be used normally. This display can occur when the spa filter is dirty or when something
limits the flow of water in the pipe.
When the 3 flashing dots appear, the heater is shut off.
Power can remain on while the following steps are performed.
· A system with a flow switch displaying
the pressure or flow switch not activated
message will not be corrected by
installing a pressure switch.
· A system with a pressure switch
displaying the pressure or flow switch
not activated message will not be
corrected by replacing the pressure
switch.
· Verify that the pump is working. If the
pump is not functioning properly, refer
to the pump section of this manual.
· Make sure to clean the filter and to
check for air locks, closed valves or
anything that could restrict the flow of
water.
· Verify that the pressure or flow switch
cable is properly connected to the
pressure or flow switch and the printed
circuit board.
· If the problem still exists, lower the Set
Point temperature to 60°by pressing
and holding the Down Arrow Key. After
a 20 second cool down the pump will
turn off. Short the two terminals of the
pressure/flow switch cord using the
jumper cable. 3 flashing dots should
appear on the display.
· This message identifies the pressure or
flow switch as the source of the
problem.
· Readjust the pressure or flow switch. If
it is not possible, replace the switch.
· If the 3 flashing dots did not appear in
the previous step, the problem could be
with the switch cable or the system
circuit board.

Temperature Sensor
The system is constantly verifying that the reading of the temperature probe is within limits. If the actual spa water
temperature greatly differs from that displayed by the spaside control or if 32°F is constantly displayed, this indicates
a problem with the water temperature sensor.
Note that the temperature of the water should be over 35°F to perform the following steps.
Press a key after each step to reset the system.
Power can remain On.
· Verify that the temperature sensor is
properly connected to the printed circuit
board.
· Disconnect the sensor connector and
try and clean the connector pins. A
small coating of film can cause a bad
connection. Also inspect for bent pins.
· Reconnect the sensor.
· If the display is still unchanged on the
spaside control, replace the sensor with
a spare and place the probe in the spa
water.
· If this solved the problem, replace the
sensor. Replace the printed circuit
board if the problem has not been
corrected.
ECO-5 / 6100 Error Messages
High Limit Sensor / Over Heat
If 3 flashing dots appear on the spaside control and the LED error indicator on the printed circuit board is illuminated,
there is either a problem with the high limit temperature sensor or an over heat condition has occurred. This will
happen whenever the water temperature read by the high limit temperature sensor exceeds 115°F.
Power to the system must be turned off then on to reset the system.
Power can remain On.
If the reading is
below 115°F:
· With an accurate thermometer measure
the temperature of the water.
· Check to see if the heater housing is
hot.
· If the heater housing is hot, check for an
obstructive flow of water (closed valves or
dirty filter).
· If after clearing any obstructions the
error still appears on the display and the
LED error indicator is still illuminated on the
printed circuit board, replace the printed
circuit board.

High Limit Sensor / Over Heat
If the temperature of the water is at or higher than 115°F and the display on the Spaside control IS the right
temperature, perform the following tests.
If the weather is
very warm:
· Remove the spa cover. Wait until the
spa cools down (Add cold-water if
necessary).
If the weather is not
a factor:
· Lower the Set Temperature below the
actual temperature of the water (The
Heater On indicator on the spaside
control should turn Off).
· Open the access panel on the control
box. With a voltmeter, read the voltage
between P10 and P17 on the printed
circuit board. This is the power supply
for the heater relay coil. If you do not
read 120 VAC, the pump may be
overheating the water during the
filtration cycle. Lower the filter cycle
duration.
To Lower the Filter
Cycle
· Press both the Light and Up Arrow Key.
The current duration will be displayed.
· Use the Down Arrow Key to lower the
value. (60, 120 or 180)

Low Level Programming
It is possible to change the parameters of the Equipment System by positioning specific jumpers located on the
system board.
Jumper 1 Position 1: (High Current –240vac): There is no current restriction. This allows the
heater to operate with the pump in high speed.
(Current Limiting) Position 2: (Low Current –120vac): The system will not turn the heater on when the
pump is in high speed. The heater indicator will flash on the Spaside to tell
the user that there is a call for heat but the heater is not allowed to start.
Jumper 2 Position 1: Two Speed Pump
(1 or 2 Speed Pump ) Position 2: Single Speed Pump
Jumper 3 Position 1: 60 minutes Duration, Once a Day

ECO-5 / 6100 Identified Problems
Nothing Works!
If everything is connected properly and nothing seems to work, there is probably a problem with the power supply. If
you detect Low or High voltage conditions at the input power connection contact an electrician.
Perform the following tests to identify and correct the problem:
120V Operation · Measure the input voltage between Line
1 (P8) and Neutral (P10). You should
read approximately 120 VAC. (if you do
not get a good voltage reading, check to
make sure the system rocker switch is
in the ON position and that the Line 1
fuse is good.)
· If you are getting good voltage readings
but nothing seems to work, verify that
the Spaside control is properly
connected to the system circuit board
(and external receptacle, if applicable).
If nothing works, replace the circuit
board.
