NO-FAULT 6000 HEATER AND HEATER THERMAL
CUT-OFF
® ® ®
The Hot Spring Spa No-Fault 6000 Heater is called the No-Fault Heater because it comes with an unconditional
warranty. This means that any failure during the stated warranty period that requires the replacement of the heater will be
warranted unconditionally.
®
It is important to note that the Hot Spring Spa heater is protected by both the heater high limit thermostat circuit and the
heater thermal cut-off. The causes of heater high limit tripping are discussed in the previous section.
If the spa is not heating, but the pump and light operate, then the heater thermal cut-off may have tripped. To reset it,
simply locate the red button on top of the heater and push down on the button. If the heater energizes once you push the
heater thermal cut-off button, this indicates reduced water flow through the heating system. Tripping of the heater thermal
cut-off 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, or 4) an air lock in the plumbing lines.
Once the problem has been identified and corrected the heater thermal cut-off will be able to be reset which will energize
the heater.

SILENT FLO 5000 CIRCULATION PUMP AND
CIRCULATION PUMP THERMAL CUT-OFF
®
The Hot Spring Silent Flo 5000 circulation pump is a dedicated, water cooled, energy efficient, quiet pump that provides
®
continuous filtration for the spa. Since the Silent Flo 5000 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 ofone 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, 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.
®
FRESHWATER II OZONE SYSTEM
®
The FreshWater II 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 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 Spring Spa dealer if your spa requires troubleshooting beyond the scope of this manual.
®
Freshwater II 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 page 43 of this manual for
ozone injector cleaning instructions.
