SERVICE INFORMATION
GENERAL INFORMATION
Your Hot Spot
®
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, high limit thermostat,
or pressure switch, 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, the following items should be checked:
1. Check the power supply to the spa.
2. Check the GFCI (located at the end of the cord in standard models or in the electrical subpanel in 30 amp converted models) and see
if it has tripped. 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.
3. If, upon checking the GFCI you find it has 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 either the circuit was overloaded or a ground fault exists
between the breaker panel and the spa receptacle. Contact a qualified electrician.
4. If, upon checking the main house breaker, you find no failures, the heater high-limit thermostat should be checked. Tripping of the
heater high-limit thermostat is normally a result of one or a combination of any of these problems: 1) blockage within the system
plumbing, 2) switch malfunction in the heater circuit, or 3) the low speed mode of the jet pump is not functioning.
5. If the heater high-limit has tripped, the control panel display will read “
◆◆◆”. Reset the heater high-limit by allowing the water to cool
and disconnecting power to the spa for at least thirty seconds. If the heater high-limit continues to trip, contact an Authorized Service
Technician for a complete diagnosis.
If the spa does not function and the GFCI or GFCI breaker and heater high-limit have not tripped, then the problem should be referred to
an Authorized Service Technician. Refer to the Troubleshooting Guide for additional service information.
FRESHWATER

III HIGH OUTPUT OZONE SYSTEM
The FreshWater III high output 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 (also functions as the floor drain) 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 buzz or hum is not audible, verify that
the generator is completely plugged into the spa’s control box.
If the unit is plugged in and power is connected to the spa, then the fuse (for the ozone generator) should be checked.
WARNING: Contact your Hot Spot Spa Dealer if your spa requires troubleshooting beyond the scope of this manual. Freshwater III
high output ozone systems should only be serviced by a qualified technician.
WARRANTY NOTE: Cleaning of the ozone injector is not covered under the warranty. Refer to the Ozone section of this manual for ozone
injector cleaning instructions.
The FreshWater III ozone system WILL ONLY operate when the low speed of the jet pump is on.
• During the low speed cycle, you will see bubbles escaping from the heater return, these bubbles come directly from the operating
ozone unit.
• The Circulation cycle must be activated in order to ensure adequate ozone circulation time. The Circulation cycle (when activated) will
turn the jet pump on low speed for a four-hour cycle daily. See CIRCULATION CYCLE in the HEATING AND HYDROMASSAGE
SYSTEM section of the Owner’s Manual for more information.
The FreshWater
®
III high output ozonator WILL NOT operate when the high speed of the jet pump is on.
• During the high speed cycle, you will also see bubbles escaping from the floor drain, however, the ozone unit is off and the bubbles that
are visible are air bubbles only!
