Service Information

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, or resetting a

high limit thermostat 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. 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.

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 Troubleshooting Guide

for additional service information.

HEATER AND INTEGRATED

PRESSURE SWITCH

WATKINS WELLNESS unconditionally warrants the 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

heater.

It is important to note that the 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

4. An air lock in the plumbing lines

5. Circulation pump not properly working

Once the problem has been identified and corrected the pressure switch

will close which will energize the heater.

CIRCULATION PUMP AND

CIRCULATION PUMP THERMAL

CUT-OFF

The circulation pump is a dedicated, water cooled, energy efficient, quiet

pump that provides continuous filtration for the spa. Since the 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.

MISCELLANEOUS SERVICE

INFORMATION

The control and high-limit thermostats are equipped with electronic

sensors that are connected to the spa’s plumbing. Never cut or kink the

wires that connect the sensors to the thermostats within the control box.

The jet pump is equipped with a thermal overload cutoff switch that is

designed to protect the pump from overheating. If the pump shuts itself

off in an older spa, it could indicate failure of the pump motor bearings. If

the pump shuts itself off in a new spa, it is usually the result of one or a

combination of the following factors:

• Thermal overload: Although mass-produced, not all thermal overload

cutoffs are exactly the same. Some are more sensitive than others and

will shut the pump off at lower temperatures.

• High temperature: All CALDERA spa models are equipped with a jet

pump shroud that vents the heat generated by the pump motor to the

outside of the equipment compartment, and back into the spa water. If

the vent is blocked by masonry, grass or debris, overheating of the jet

pump may occur. Once the pump motor has cooled sufficiently and any

blockage has been removed from the vent opening, the jet pump can

be restarted.

• 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 wiring: If the spa is connected with an extension cord, and/

or the house wiring is undersized, the pump may starve for voltage and

therefore may draw more amperage and generate excessive heat.
