Troubleshooting Guide
PHT 1000 and 2002
(T & LT models)
Temperature Readout is Wrong
– Remove temperature sensor/thermister from the tub location and submerge it directly into the water. This
will verify if the sensor has been installed where ambient air has affected it or if it is defective.
– Insulate the through wall dry well so the ambient air does not influence the temperature measurement.
Overheat
– If the water is too hot and the high limit has tripped, the water must be allowed to drop to less than 112°F
before it will reset. Reset by pressing the heat key at the topside control or restarting the system.
– The circulation of the water may be too low, allowing the heater body to overheat. Be sure that all valves are
fully open to allow maximum water flow over the heater element.
The friction and radiant heat from the pump motor can cause an extremely high ambient temperature around
the spa and the equipment causing an overheat condition. If this condition is suspect, try running the spa with
the equipment door off to see if it still overheats.
Pump(s), Blower or light does not shut off
– Try new topside control
– Replace main board
Circulation pump does not work
– Check the fuse and power connections.
Light does not work
– Press Light key at top side
– Check bulb
– Check 12V out to light at J4 and J5
