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 display - - - - . 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.
MISCELLANEOUS SERVICE INFORMATION
The jet pump is equipped with an 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.
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.
ACTS INVALIDATING WARRANTY
The limited warranty is void if the Hot Spot Spa has been subjected to alteration, misuse or abuse, or if any repairs on the spa are attempted by
anyone other than an authorized representative of Watkins Manufacturing Corporation. Alteration is defined as any component or plumbing
change, electrical conversion, or the addition of any non-approved sanitation, or water purification device, or heating system which contributes to
a component failure, unit failure, or unsafe operating condition. Misuse and abuse shall include any operation of the spa other than in accordance
with Watkins Manufacturing Corporation printed instructions, or use of the spa in an application for which it is not designed; specifically: use of the
spa in a non-residential application; damage caused by operation* of the spa at water temperatures outside the range of 35°F and 120 °F (2°C and
49°C); damage caused by a dirty, clogged, or calcified filter cartridge; damage to the spa surface caused by the use of Tri-Chloro Chlorine,
BCDMH, chemical tablets in a floater, acid, or any other spa chemicals, or spa surface cleaners which are not recommended by Watkins
