General Troubleshooting & Servicing of Spa's Electrical Equipment
DANGER
Risk of electric shock. Before working with any electrical
connections, make certain that the Main Power breaker from
the house breaker box has been turned off.
WARNING
ALL ELECTRICAL WORK MUST BE PERFORMED BY A
QUALIFIED ELECTRICIAN AND MUST CONFORM TO ALL
LOCAL CODES.
IMPORTANT
DUE TO THE DANGER OF SEVERE ELECTRICAL SHOCK,
LOCATE ALL POWER DISCONNECTS BEFORE SERVIC-
ING A SPA. PRECAUTIONS MUST BE TAKEN WHENEVER
WORKING WITH BREAKER BOXES, G.F.C.I.’S, OR SERVICE
DISCONNECTS.
Always refer to the wiring diagram that is included with each
system on the inside of the system box cover. Use this diagram
for voltage measurement points, and for proper reconnection
of wires.
HIGH VOLTAGE CAN SERIOUSLY INJURE OR KILL!
ONLY EXPERIENCED TECHNICIANS SHOULD SERVICE THIS EQUIPMENT.
DO NOT REMOVE THE PROTECTIVE COVERS FROM ANY ELECTRICAL ENCLOSURE, OR ATTEMPT TO SERVICE ANY RELAT-
ED ELECTRICAL DEVICE, UNLESS YOU ARE A QUALIFIED ELECTRICIAN OR SERVICE PROFESSIONAL.
SAFETY TIPS
Keep children and pets away.UÊ
Be aware of your surroundings. Standing in water whileUÊ
repairing a spa puts you at serious risk.
Avoid working in cramped or crowded conditions.UÊ
Consider placing a padlock on the service panel to lockUÊ
out anyone who might power up the system.
A terminal marked “GROUND” is provided
within the System Control Center enclosure.
To reduce the risk of electrical shock, connect
this terminal to the grounding
terminal of the electric supply
panel with a continuous
green insulated copper wire
equivalent in size to the circuit
conductors supplying this
equipment, but no smaller than
#12 AWG.

G.F.C.I. Troubleshooting
IF CORRECT WIRING IS VERIFIED
Check to see if the proper G.F.C.I. is installed.UÊ
Check the label in the system box near TB1 to determine theUÊ
maximum amperage draw for the system.
Be sure the G.F.C.I. is rated for more amperage than theUÊ
system will draw.
For a 240 V dedicated system, a 2-pole G.F.C.I. with no loadUÊ
neutral is acceptable.
For a 120/240 V system, the G.F.C.I. must include a loadUÊ
neutral out.
If the white load neutral wire is routed from the G.F.C.I.UÊ
neutral bar directly to TB1 in the system box, then the G.F.C.I.
will trip when a 120 V device is activated.
For a detailed wiring checklist, please review the previ-UÊ
ous segment of this manual on proper G.F.C.I. wiring or the
G.F.C.I. manufacturer’s instructions.
If the wiring is correct and the G.F.C.I. will not reset, thenUÊ
unplug the pump and try to reset the G.F.C.I.
If the G.F.C.I. trips again, then unplug the blower and resetUÊ
the G.F.C.I.. If the G.F.C.I. continues to trip, then do the same
procedure for the ozone generator.
If the G.F.C.I. stops tripping after you unplugged one of theUÊ
spa’s components, turn off the power to the spa then plug in
each component except the one that tripped the G.F.C.I.
Power up the system. If the G.F.C.I. no longer trips, then youUÊ
have correctly identified the problem.
Repair or replace the component as instructed by the spaUÊ
manufacturer.
If you have unplugged all of the spa’s components and theUÊ
G.F.C.I. still doesn’t reset, then the problem is most likely a
ground fault in the heater.
TO DISCONNECT THE HEATER
First, turn off the main circuit breaker, then remove bothUÊ
heater straps or wires from the system heater output, not
the heater itself.
After restoring the power, try to reset the G.F.C.I. again. If itUÊ
no longer trips after the system calls for heat, then replace
the heater.
If the G.F.C.I. still trips, look for pinched or shorted wires atUÊ
the transformer. Make sure that the screws that attach the
transformer to the system box have not pinched or damaged
the insulation of the transformer wires.
If the transformer wires are undamaged, check for any otherUÊ
pinched wires. Refer to the wiring diagram to verify the
correct wiring of the control system.
If everything looks to be in perfect working order, then theUÊ
G.F.C.I. may be defective.
Keep in mind that a majority of G.F.C.I. tripping problems can be attributed to incorrect wiring. G.F.C.I. troubleshooting
usually finds the problem.

Breaker (G.F.C.I.)
WARNING: THE OWNER SHOULD TEST AND RESET
THE G.F.C.I. ON A REGULAR BASIS TO VERIFY ITS
FUNCTION.

VOLTAGE VERIFICATION - MOST G.F.C.I. PROBLEMS ARE DUE TO LOW VOLTAGE
IMPORTANT:
IF THE VOLTAGE IS NOT WITHIN THE ACCEPTABLE RANGE, CALL AN ELECTRICIAN
OR THE LOCAL ELECTRIC COMPANY TO DIAGNOSE THE PROBLEM.
CHECK THE VOLTAGES AT:
1. Breaker Box Voltage Check
2. G.F.C.I. Line-In Voltage Check.
3. G.F.C.I. Load Out Voltage Check
4. System Box Check At Tb1
CHECK UNDER PEAK LOADS -- TWO TYPES OF PEAK LOADS
1. Spa System Peak Loads - Pumps, Heater, Blower & Light On
2. Household Peak Loads - May Be In Afternoon On Hot Day
Use Recording Meter If Possible - Records Max & Min Volts

Voltage Checks: Breaker Box, G.F.C.I. & System Box
When checking for proper voltage, keep in mind that the acceptable voltage range isUÊ +/- 10% of the recommended voltage.
Acceptable voltage when 120 V is specified is between 108 and 132 V.UÊ
Acceptable voltage when 240 V is specified is between 216 and 264 V.UÊ
Diagrams are on the following pages.UÊ
120 Volt Systems - 120V ± 10% - 108V - 132V
240 Volt Systems - 240V ± 10% - 216V - 264V
No More Than 2% (5 Volt AC) Difference Between Voltage
at the Breaker Panel And Voltage at the System.

Wiring Checks
WIRING CHECK PRECAUTIONS
When working in a system box always be aware that it mayUÊ
contain high voltage.
Always keep your fingers and hand tools away from anyUÊ
wiring or circuit board when the power is on. Touching any-
thing in these areas can result in serious injury.
All service calls, no matter how minor, should include aUÊ
complete wiring check, beginning with the house breaker.
CHECK FOR LOOSE CONNECTIONS OR DAMAGED
WIRES
Make sure the power is off before you touch any wiring.UÊ
Once the power is off, carefully examine all wires for cuts orUÊ
defects.
SYSTEM BOX WIRE GAUGE CHECK
When inspecting the wiring for any control system, note that
connections for the incoming wires are clearly labeled at the
main terminal block.
30A service – minimum ten gauge copper wire.UÊ
40A service – minimum eight gauge copper wire.UÊ
50A service – minimum six gauge copper wire.UÊ
These wires must connect the house breaker box, through the
local disconnect, to the main terminal block. The wiring diagram
inside the system box shows the main terminal block as TB1.
IMPORTANT
Using non-copper wire can be dangerous, and also can be the
cause of a spa’s malfunction. If non-copper wire is used at any
point, we do not recommend servicing the spa until an electri-
cian replaces it with the proper gauge copper wire.
IMPORTANT
This service must be single phase. Any abnormal voltage read-
ing requires an electrician. Do not attempt to fix these types of
problems yourself. High voltage can seriously injure or kill.

Testing a System with Power
LOW VOLTAGE
At Balboa, it’s been our experience that the majority of the
problems associated with electronic control systems are due to
low voltage.
BROWN OUTS
“Brown outs” can have an effect on the spa’s operation in a
variety of ways. The control panel may go blank, have scrambled
messages on the LCD, or only a few features will function.
CHECKING THE SYSTEM POWER INPUT FUSE
WARNING
THESE PROCEDURES ARE PERFORMED
WHILE THE SYSTEM IS POWERED UP AND
RUNNING UNDER PEAK LOADS.
Measure between the white TB1 terminal and power inputUÊ
fuse. You should see 120 volts.
If the system is equipped with the additional power inputUÊ
fuse, measure additional power input fuse in the same
manner. You should also see 120 volts.
If the system is getting the proper
voltage at TB1, but still doesn’t operate,
then test for a blown power input fuse.
(See section: Testing Pump Fuses for Damage)

If your system uses 240V peripheral devices (below):
Measure between theUÊ red TB1 terminal and power input
fuse. You should see 240 volts. Measure the other side of
the input fuse. You should also see 240 volts.
If you determine that there is no voltage at both locations,UÊ
then the system power input fuse needs to be replaced.
Only use a fuse of the same type and amp rating when you
replace any fuse.
NOTE FOR ALL SYSTEMS:UÊ In each situation, the most
likely reason for the system power input fuse to blow is a
pump problem. However, on occasion, a blower problem
may also cause this fuse to blow if a 10A blower fuse is not
built in.
Once the power input fuse has been changed
Probe the red wire and the white neutral wire. Again,UÊ
voltage must be between 108 and 132 V.
Check the voltage between the black and red wires again.UÊ
Acceptable voltage range is between 216 and 264 V.

Testing a System with Power (cont.)
THESE READINGS SHOULD BE TAKEN UNDER
PEAK LOAD CONDITIONS.
IMPORTANT
If the voltage is not in the acceptable range, call
an electrician or the local electric company to diagnose
the problem.
TO DETERMINE THE CAUSE OF A BLOWN POWER INPUT
FUSE
Perform the following sequence of tests.
Test the System
Turn the power off.UÊ
Be sure to replace the system power input fuse with theUÊ
same type.
Unplug the blower and all pumps.UÊ
Restore the power and verify system operation.UÊ
If the fuse blows, power down the system and then re-checkUÊ
the internal system wires and connector for burns, cracks or
cuts in insulation.
Or, if the fuse does not blow, turn the power off and plug inUÊ
the pump.
NOTE: Be sure to test each device individually.
Test the Pump
Restore the power and activate the pump.UÊ
If the fuse blows, there is aUÊ pump problem.
If the fuse does not blow, turn off the power.UÊ
Test the Blower
Plug in the blower.UÊ
Power up the system and activate the blower.UÊ
If the fuse blows, then there is aUÊ blower problem.
If the fuse does not blow, the combined pump and blowerUÊ
amperage may be excessive. To verify this, first check
with your spa manufacturer for amperage draw limits on
each device.
Since the blower should now be running, you can checkUÊ
the amperage draw with an ammeter by measuring around
the black blower wire and compare with manufacturer’s
specifications.
TEST THE AMPERAGE DRAW
Turn off the power, disconnect the blower, make sure theUÊ
pump is plugged in, and restore power.
Start the pump and switch toUÊ
high speed (if available), this
should draw the most current.
Make sure all jets and valvesUÊ
are open.
Check theUÊ amperage at the
red pump wire. Compare your
reading with manufacturer
specifications. (If the other
plug-in devices exist, they
should be tested in the
same way.)
If the amperage draw forUÊ
each device is within manufacturer’s specifications, the
problem could be a nuisance spike in the pump, or water in
the blower.
NOTE: These slow-blow fuses are not always discolored when
blown. Always test continuity of a fuse with an ohmmeter.
NOTE: Miswiring of the spa is the most common reason for this
fuse to blow. However, a lightning strike in the area is a possible,
though less likely, cause of the failure.
ELECTRICAL PROTECTION
1. Local Disconnect:
A local disconnect (sometimes referred to as an “electrical
disconnect”) is installed apart from the main service panel.
The local disconnect must be installed where readily acces-
sible and within sight of the spa, but at least 5’ (1.5 meters)
from the inside wall of the spa.
2. GFCI:
It is required by code to install a Ground Fault Circuit Inter-
rupter (GFCI) in the supply power for a spa.
NOTE: A GFCI power cord is included with a 120VAC spa. This
can be used for a cord-connected 120V setup only, and only in
place of a stand-alone GFCI.

SAFETY AND ELECTRICAL SYSTEMS
Use minimumUÊ 6AWG copper conductors only.
Torque field connections between 21 and 23 in-lbs.UÊ
Connect only to a circuit protected by aUÊ Class A Ground Fault
Circuit Interrupter (GFCI) CSA enclosure: Type 2.
The BP Spa Control Systems are classified as a “continuousUÊ
duty appliance” and is intended primarily for installation at
a single family dwelling. The installation recommendations
and instructions contained in this manual are directed solely
toward these issues.
WARNING!
If there is any doubt whether the system that you are installing
into does not have these features, contact a licensed, qualified
electrician. Do not attempt to modify the wiring yourself.
PRELIMINARY PANEL CHECK
If the problem is not obvious, look on the topside controlUÊ
panel for diagnostic messages.
If no messages are seen, run through all spa functions andUÊ
note any inconsistent operation.
Most error messages are stored in the fault log. To view theUÊ
fault log, the spa must be in test mode and the spa light
must be turned on.
Once you have determined that proper voltage is running through
the circuit board and transformer, continue to the topside control
panel. A panel that is not functioning properly may include the
following symptoms: low voltage such as missing or scrambled
segments, missing icons on the LCD, non-functional LED’s, or
nonfunctional buttons. If any of these symptoms are present,
perform the following:
Turn the power off and unplug the panel from theUÊ
circuit board.
Then, plug in your test panel and restore power. If every-UÊ
thing functions normally, replace the topside panel.
Disconnect ozone generator (if applicable).UÊ
If you still see symptoms of low voltage, such as a sluggish,UÊ
blank or partially blank panel, or if the display or the LED’s
do not function at all, turn the power off; unplug the ozone
generator (if equipped); then restore power to the system.
If the problem persists, turn off the power and replace the
circuit board.
FLASHING HEAT LED ON TP600 ("HEAT WAITING")
When there is a call for heat, the system will start the heater for
a few seconds and the Heat LED will light. After a few seconds
of heat, the heater will shut off for 90 seconds and the sys-
tem will look at the sensors to be sure they are within the M7
parameters for flow and a safe environment to run the heater.
During this 90 second wait time, the Heat LED will flash quickly,
or "shimmer", until the heater comes on again to heat. There is
no voltage to the heater during this cycle. This is normal for M7.
Once the heater comes back on, the LED will be on without shim-
mering. On the TP800 and TP900 panels, the screen will display
"Heat Waiting".
HEATER START UP INFORMATION
On M-7 systems, the heater goes through a testing phase every
time it starts up to assure that there is adequate water flow. This
provides sophisticated dry fire and low flow protection. It can be
confusing if you don't know what to expect. Step by step, here is
what happens. (Note that the timing/temperature details may be
slightly different on some older M7 systems.)
Prior to heating, the pump is run for at least two minutes,UÊ
and then the temperature difference between the sensors
is assessed. It must be 2°F/1.0°C or less for heating to
proceed, otherwise an error is issued.
The heater turns on for 6.5 to 18 seconds (depending onUÊ
heater voltage and wattage). At this point, the heat indicator
on the panel is "solid". During this time the panel is not
immediately responsive.
The heater turns off for 90 seconds, making sure that theUÊ
water flow keeps the temperature rise small and short.
(Abnormal water flows, or lack of water, will produce a large
and/or long temperature rise, and the system faults in that
situation.) At this point, the heat indicator on the panel may
appear to "shimmer" or "dim" (on some panels this may be
less obvious from certain angles and more obvious from
other angles, or in different lighting).
If the dry fire test has passed, heating turns back on to heatUÊ
the spa. The heat indicator on the panel returns to "solid".
During spa heating, a difference between the sensorsUÊ
of 2°F/1.0°C, or perhaps 3°F/1.5°C (at least with 4-6kW
240V heaters), is considered normal. A significantly higher
difference, however, is usually indicative of a flow problem,
and will cause a fault which disables the heating for at least
a minute (and then restarts the whole above process).
See manufacturer’s owners manual or reference card for general information on operating the spa, including
programming filters and other settings that are changed from the topside control panel.
