Testing a System with Power (cont.)
MOST PROBABLE OVERHEATING CAUSES, INSPECT
THESE FIRST
Check slice or ball valves. Make sure that they are open. UÊ
Make sure the correct pump is installed. UÊ
Clean the filter/skimmer if there is any blockage. UÊ
Check heater element alignment. UÊ
Check for debris on the heater element. UÊ
In extremely hot weather, check for proper cabinet ventila- UÊ
tion.
Make sure the temperature sensor is fully inserted into the
UÊ
sensor fitting on the heater.
Check for excessive filter duration.
UÊ
Check the water level. UÊ
Check the water temperature with an accurate temperature UÊ
thermometer. Remove the spa cover and allow the water to
cool to below 108° F. Adding cool water may be necessary.
Touch any button to reset the system. If the water is still
hotter than the set temperature, press the blower button (if
applicable) to cool the spa.
If the Problem Recurs, test the Sensor Set. UÊ
NOTE:
A common programming mistake is overlapping filter
times that may cause the spa to filter continuously.
If alternating with temperature, it may just be a temporary
condition. If flashing by itself, spa is shut down.
If the panel also displays “Service Req” spa is shut down.
If the spa shuts down due to this error, one (or both) of the
sensors are probably reading several degrees off. If the problem
recurs, test the sensor set.
FREEZE CONDITION
When either sensor reads below 40°F (4°C), the system provides
freeze protection. It automatically activates the pump (and the
heater if necessary) to circulate the water and warm the plumb-
ing. The equipment stays on until the sensors detect that the
spa temperature has risen to within 15°F of the set temperature.
The other pumps and the blower will purge for 30 seconds to 2
minutes at the end of the freeze condition. If pump 1 was turned
on due to this reason alone, this message will appear for up to
two minutes right after very cold water is detected.
NOTE: Internal freeze protection only functions when there
is proper power running to the spa, and the control system is
operational. Using an optional freeze sensor may be necessary
in extreme climates to prevent plumbing damage, but will only
work properly if placed inside the spa skirt in the coldest area.
All spa models are different in shape and size and have different
thermal characteristics; therefore, Balboa Water Group cannot
be held responsible for freeze damage to the spa’s plumbing.
Testing is the responsibility of the spa manufacturer and must be
done to determine the best location for the freeze sensor.
SOME TROUBLESHOOTING SCENARIOS
You find out the system is in “OHH”. This alone doesn't explain a
lot. What led up to the “OHH” is much more important. If it's a
Prestige, review the fault log carefully. Otherwise, see if the user
has any additional information (for example, how long before
the “OHH” was the spa panel last checked, and how hot was
the water then). If the spa has cooled, see whether the problem
can happen again, this time watching carefully to see if there
are additional clues leading to the “OHH” (for example, other
messages that appear shortly before the “OHH” happens).
You find out the system keeps showing “HFL,” or is now in “LF,”
or is shut down due to a "dry" fault. Put the spa in test mode
with the light on, so that you see the two sensor temperatures.
Are they normal (within 1°F/0.5°C) when not heating? How far
apart are they when heating? “HFL” happens when they are
6°F/3°C apart (4°F/2°C on 120V and other low-heater-wattage
systems), see how quickly that happens after heating starts. If
it's getting close to that right away, it's probably a consistent
flow problem, but if it's nowhere close to the “HFL”-causing
temperature difference, the flow problem may be intermittent or
only occur in certain specific situations.
TEST MODE
Test modes vary for different systems and configurations. Please
refer to the specific Tech Sheet applicable.
MESSAGE CODES
Refer to Tech Sheets for each system code. Or, a general set of
codes for BP systems is found under the sectionTP400, TP600
Message Codes in this manual. Message codes are the same
for all TP panels.
