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, resetting a high limit
thermostat or replacing a light bulb 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.
NOTE: 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.
In 115 volt models, check the GFCI at the end of the power cord. In 230 volt models, 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, or 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.

FRESHWATER III HIGH OUTPUT OZONE SYSTEM
The FreshWater III ozone system is practically maintenance-free because it is located within the spa's equipment compartment. If bubbles are
appearing at the spa's heater return but the smell of ozone is not noticeable (the water may also appear not as clear as usual) then the operation of
the ozone generator should be checked. Carefully open the equipment compartment door (remember to use care, as power is still connected to
the spa) and verify that the CD tube and its transformer are energized (a slight buzz will be emitted from the ozone generator housing). If a slight
