GENERAL INFORMATION

Your 

CALDERA

 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 

VACANZAZ

 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 CALDERA spa has been improperly 

installed, subjected to alteration, misuse, or abuse, or if any repairs on 

the spa are attempted byanyone other than an authorized representative 

of Watkins Manufacturing Corporation. Alteration shall include 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 component or unit failure or unsafe 

operating system.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 1.7°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, misuse of chemical tablets in a floater, 

acid, or any other spa chemicals or spa surface cleaners which are not 

recommended by Watkins Manufacturing Corporation; damage caused 

by allowing undissolved spa sanitizing chemicals to lie on the spa surface 

(no spa surface material can withstand this kind of abuse); damage 

to components or spa surface caused by improper water chemistry 

maintenance; and damage to the spa surface caused by leaving the spa 

uncovered while empty of water and in direct exposure to sunlight (this 

may cause solar heating distress in warm weather regions). These are 

considered abuses and may invalidate this warranty.
*Operation of the spa does not mean “use” of the spa! Watkins 

Manufacturing Corporation does not recommend using the spa if the 

water temperature is above or below the spa’s control panel temperature 

range.

DISCLAIMERS

Watkins Manufacturing Corporation shall not be liable for loss of use 

of the

 VACANZA
