Troubleshooting Guide
PHT 2004 ULX Controls
(ULXT models)
No Heat
– Check the topside control for “HL” Error Condition. This indicates that the system has overheated. Make sure
the temperature has fallen to less than 112°F and press the Heat (Up/Down key) to reset.
– Check for flashing LED at topside control to indicate heat demand
– Check that filters are clean
– Check to see if the board LED at the equipment panel is on. This indicates a flow problem. If this light is off
and there is still no heat, the element should be checked for continuity. If the element is open, it needs to
be replaced.
– If the board LED still does not turn off, then the pressure switch may need to be adjusted. The pressure switch
is located on the heater body and has a small plastic screw (for flat screw driver) on it. This plastic screw (for
flat screw driver) should be turned counter clockwise to allow the heater to run on less water flow/pressure.
This pressure switch is a protection switch that is meant to turn the heater off if the pump fails to operate
or if there is not enough pump pressure. A test to see if the pressure switch has been adjusted correctly is
to unplug the circulation pump and see if the heater shuts off. It should operate again when the pump is
plugged back in. The heater should not be allowed to operate under static (gravitational) pressure when the
pump is not on as it will cause an instant overheat.
– If a flow switch is used it must be checked for continuity when closed.
– Replace the circuit board if the above remedies do not work.
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 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.
