  If the water temperature isn't increasing even though the red indicator is lit on your Intex Swimming Pool Heater, make sure to use a pool or solar cover when the pool is not in use. Also, the pool size or water capacity may exceed the heater's capacity, so increase the heating time accordingly.

  If the red indicator on your Intex Swimming Pool Heater isn't lighting up during use, first ensure the power cord is properly plugged in. Then, check that the knob is fully switched to the 'I' (on) position. Also, verify that the GFCI/RCD plug is turned on by re-plugging it and pressing the 'RESET' button. Another potential cause is that the water temperature might be too high; the heater will cut off power above approximately 95°F (35°C) and resume when it drops below 82°F (28°C). Finally, check that there is sufficient water flow by turning on the filter pump and ensuring the plunger valves are open, filter cartridges are clear, and any trapped air is released from the circulation line. Also, check the direction of water inlet and outlet hoses, and reverse if necessary.
