  If your Hurlcon Swimming Pool Heater won't light, several issues could be the cause. First, ensure the power to the heater is on and the pump is running. If the pump isn't running, start it. Check for leaks if the pump is airlocked, and clean the filter or pump strainer basket if they're dirty. Also, make sure the thermostat is turned on and the set temperature is higher than the water temperature. If the gas control is defective or the water is too hot, shut off the gas supply and call for service. If a fault condition is displayed, refer to the fault indication table.

  Short cycling (rapid on and off operation) in your Hurlcon Swimming Pool Heater can be caused by a few things. Check for insufficient water flow by cleaning the filter and pump strainer. Defective wiring can also cause this issue, so repair or replace any faulty wiring. Finally, a defective high limit or thermostat could be the culprit; repair or replace these components if necessary.

  Knocking noises in your Hurlcon Swimming Pool Heater may occur if the heater continues to operate after the pump has shut off, or if the heat exchanger is scaled. In either case, the suggested solution is to shut off the gas supply and call for service.
