  If your Astralpool Heater will not light, first ensure the power to the heater is on. Then, verify the pump is running. If the pump is running but the heater still won't light, check for leaks, clean the filter and pump strainer basket. Also, make sure the thermostat is turned on and that the set temperature is higher than the current water temperature. Finally, confirm the gas is turned on. If a fault condition is displayed or the heater is in a fault condition, refer to the fault indication table.

  If your Astralpool Swimming Pool Heater won't light, first ensure the power to the heater is on. Then, check if the pump is running and start it if necessary. Also, inspect for any pump air locks and leaks. A dirty filter or clogged pump strainer basket can also prevent ignition, so clean them. Verify the thermostat is on and the set temperature is higher than the water temperature. If the display shows a fault condition due to the water being too hot, consult the fault indication table. Finally, confirm the gas is turned on.

  If your Astralpool Swimming Pool Heater is short cycling, which means it's rapidly turning on and off, the most likely cause is insufficient water flow. To resolve this, clean the filter and the pump strainer to ensure adequate water flow through the system.

  If your Astralpool Heater is making knocking noises, it could be due to low water flow. Check the pump condition to ensure it's functioning correctly. If the heater continues to operate after the pump has shut off or the heat exchanger is scaled, immediately shut off the gas supply and call for service.

  If your Astralpool Swimming Pool Heater is making knocking noises, it could be due to several reasons. First, check the pump condition, as low water flow can cause such noises. If the heater continues to operate after the pump has shut off, immediately shut off the gas supply and call for service. Another potential cause is a scaled heat exchanger, which also requires shutting off the gas supply and calling for service.
