GENERAL INFORMATION

our 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 “HL.” 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 a qualified service technician. Refer to the Troubleshooting Guide for additional service information.
MISCELLANEOUS SERVICE INFORMATION
The high-limit thermostat capillary is not an electrical wire. It is a copper tube with a tiny bore which carries an expansive
fluid. NEVER cut, bend or kink the tube.
The jet pump is equipped with a overload cut-off switch, which is designed to protect the pump from overheating. If the
pump shuts itself off in a new spa, it is usually the result of one, or a combination of, the following factors:
High Temperature: During the summer months, especially in warmer climates, the ambient temperature contributes to
excessively high temperatures within the equipment compartment.
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 House Wiring: If the spa is not connected to a dedicated circuit, or is connected to an extension cord, or the
house wiring is undersized, the pump may starve for voltage and therefore may draw more amperage and generate
excessive heat. This will often cause the circuit breaker to trip repeatedly.
IMPORTANT:
1. If the pump is shutting down due to excessive heat, make sure the equipment compartment has adequate ventilation.
The air gap at the bottom and the jet pump vent at the bottom left corner must not be blocked. Should your jet pump
continue to shut off after short periods of use, contact a qualified service technician.
2. The Hot Spot
®
Spa is equipped with a safety suction spring valve which will break the prime of the jet pump if both
suction fittings are obstructed.
