GENERAL INFORMATION

Your HOT SPRING spa has been designed to provide years of trouble-
free use. As with any appliance, problems may occasionally occur
that require the expertise of a qualified service person. Though such
simple repairs as resetting a GFCI switch or breaker, or resetting a
high limit thermostat may not require a service call, they may indicate
that a more serious condition exists. These conditions may require an
experienced service person. Before calling for service, please refer to
the Troubleshooting Guide. Always retain your original sales receipt for
future reference.

GFCI AND HIGH LIMIT THERMOSTAT

If your spa fails to operate at any time, first check the power supply to
the spa.
Check each of the GFCI breakers in the subpanel. If a GFCI has tripped,
reset it. If it will not reset, this may be an indication of a ground fault
(short circuit) within the electrical components. Contact an Authorized
Service Technician for a complete diagnosis.
If upon checking the GFCI's you find that they have not tripped, check
the house breaker panel and ensure the main breaker for the electrical
circuit supplying the spa has not tripped. If it has, this is an indication
that the circuit was either overloaded or a ground fault exists between
the breaker panel and the spa receptacle or subpanel. Contact a
qualified electrician.
If upon checking the main house breaker and spa GFCI's you find no
failures, check the high limit thermostat. To check it, simply turn off
power to the spa for 30 seconds. This will automatically reset the high
limit thermostat if it has tripped. If the spa energizes once you turn the
power back on, this indicates reduced water flow through the heating
system. Tripping of the high limit thermostat is normally a result of
one or a combination of these problems. 1) clogged filter cartridge(s),
2) blockage within the system plumbing, 3) a non-functioning heater
circulation pump, 4) power was not disconnected from the spa before it
was drained, 5) an air lock in the plumbing lines. (The Power Indicator
on the front of the spa's control panel will also be blinking if the high limit
thermostat circuit has tripped.)
If the spa does not function after tripping and resetting the GFCI's or
resetting the high limit thermostat, then the problem should be referred
to an Authorized Service Technician. Refer to the Heater section if the
spa operates but does not heat, or refer to the Troubleshooting Guide
for additional service information.
NO-FAULT HEATER AND
INTEGRATED PRESSURE SWITCH
Watkins Manufacturing Corporation unconditionally warrants the
NO-FAULT heater against any failure that would require replacement.
This warranty's duration is equal to the time period identified in the
Component Warranty. This warranty defines unconditional as warranty
coverage without exception provided that the component has failed to
operate properly within the spa's system. This means that conditions
that would normally invalidate the limited warranty, such as water
chemistry damage, do not apply to the NO-FAULT heater.
It is important to note that the NO-FAULT heater is protected by both the
heater high limit thermostat circuit and the integrated pressure switch.
The causes of heater high limit tripping are discussed in the previous
section.
If the spa is not heating, the red and green lights are blinking, but
the pump and light are operating, then the pressure switch may be
open. Opening of the pressure switch is normally a result of one or a
combination of these problems:
1. A clogged filter cartridge
2. Blockage within the system plumbing
3. Power was not disconnected to the spa before it was drained
4. An air lock in the plumbing lines
Once the problem has been identified and corrected the pressure switch
will close which will energize the heater.
SILENT FLO 5000 CIRCULATION
PUMP AND CIRCULATION PUMP
THERMAL CUT-OFF
The HOT SPRING SILENT FLO 5000 circulation pump is a dedicated,
water cooled, energy efficient, quiet pump that provides continuous
filtration for the spa. Since the SILENT FLO 5000 pump is water cooled,
it is equipped with a thermal cut-off to prevent the pump from being
damaged by running hot when water is not present.
Reset the circulation pump's thermal cut-off by disconnecting power to
the spa and allowing the pump to cool.
Tripping of the thermal cut-off is normally the result of one or a
combination of these problems: 1) clogged filter cartridge(s), 2) blockage
within the system plumbing, 3) power was not disconnected to the spa
before it was drained, or 4) an air lock in the plumbing lines. Once the
problem has been identified and corrected the pump thermal cut-off will
be able to be reset which will allow it to operate normally.
MISCELLANEOUS SERVICE
INFORMATION
The control and high-limit thermostats are equipped with electronic
sensors that are connected to the spa's plumbing. Never cut or kink the
wires that connect the sensors to the thermostats within the control box.
The jet pump is equipped with a thermal overload cutoff switch that is
designed to protect the pump from overheating. If the pump shuts itself
off in an older spa, it could indicate failure of the pump motor bearings. If
the pump shuts itself off in a new spa, it is usually the result of one or a
combination of the following factors:
• Thermal overload: Although mass-produced, not all thermal overload
cutoffs are exactly the same. Some are more sensitive than others and
will shut the pump off at lower temperatures.
• High temperature: All HOT SPRING spa models are equipped with a jet
pump shroud that vents the heat generated by the pump motor to the
outside of the equipment compartment, and back into the spa water. If
the vent is blocked by masonry, grass or debris, overheating of the jet
pump may occur. Once the pump motor has cooled sufficiently and any
blockage has been removed from the vent opening, the jet pump can
be restarted.
• Friction: Sometimes the moving parts of a new pump are tight enough
to cause heat build-up due to friction. After a normal break-in period,
the pump will run cooler.
• Improper wiring: If the spa is connected with an extension cord, and/
or the house wiring is undersized, the pump may starve for voltage and
therefore may draw more amperage and generate excessive heat.
