Common Hurlcon / Astralpool Heater Information
Hurlcon & Astral Pool Heater Troubleshooting - Faults & Errors
Astralpool & Hurlcon Gas Heater Error Codes:
F0 - Heater locked off. Can't read temperature. Reset Power. If error re-occurs, call for service.
F1 - Thermostat reads very high temperature. Allow water to cool. Check filters are clean and there is sufficient water flow. Cycle mains power to reset. If error re-occurs, call for service.
F2 - Heater has gotten too hot. Check filters are clean and there is sufficient water flow. Wait several minutes for water to cool. Cycle mains power to reset. Clean filters, and re-try. If error re-occurs, replace Hi-Limit Switches, and brass plugs.
F3 - Temperature fault. Cycle mains power to reset. If error re-occurs, call for service.
F4 - Flame roll-out detected. This means the flames have been detected outside the burner area. If this occurs do no re-light heater. Turn off gas. Often caused by a blocked heat exchanger, corrosion or other reason for flames not to be contained within the firebox.
F6 - Heater Burning too hot. Do not use heater.
F7 - Condensate tank limit. Cycle power to reset. If error re-occurs, call for service. Condensate tank may be corroded, or heat exchanger breaking down. Often the sign of end-of-life of a Viron heater.
F8 - Commonly caused by faulty temperature sensor in the heat exchanger.
F9 - High temp in heat exchanger. Blocked Heat Exchanger or High combustion temps. Heater needs dismantling to inspect.
L - Heater locked out. Heater has tried to ignite too many times. It will automatically retry after 2 minutes. This allows combustion gases to escape before retrying. If it re-occurs, it may be faulty flame sensor, igniter, ignition module, blown burner, bad heat exchanger, etc.
Q or Ø - Heater is detecting water pressure, and is ready to ignite when temp is below set-point. If this symbol is not appearing, when pump is running, check that filters are clean, valves are in correct positions, or replace a faulty pressure switch.
* - Igniting. Spark or Hot Surface Ignitor (HSI) are trying to light.
^ - Flame Detected. Heater operating. Symbol looks like an upside-down V.
Heater Rumbling. Gas supply pressure is out of spec or heat exchanger fault. Turn off Heater. Needs gas pressure adjusted, or other issues.
Smoke coming from heater. Turn off heater immediately. Turn off gas. Do not use heater.
Water coming from heater. See below.
Astralpool IXI and Zodiac JXI:
Fault High Limit: This generally occurs due to low water flow (eg dirty filter), or when the heater has not been allowed to cool down properly. Ensure heater is only used when filter is clean and ensure you allow the heater at least 5 minutes to cool down by leaving the pump running.
To reset the Fault High Limit on a JXI or IXI heater: Hold 3 Buttons together und enter Menu. Go to "Clear Latched Fault" and clear the error. Reset power at powerpoint.
MORE INFORMATION:
Hurlcon Astralpool Viron & ICI Issues:
Due to the Viron heater's extreme efficiency, they can have a few more tedious problems, similar to higher-end cars. We see many issues caused by water & gas supply. We've listed some symptoms and causes below. Note that some symptoms can be caused by more than one thing.
Symptoms of Gas Supply Issues:
- sooting heat exchanger
- burnt heat exchanger
- rumbling or whining of heater
- blocked condensate tank
Symptoms of water issues:
- corroded brass plugs & sensors
- corroded or overheated heat exchanger
- blocked heat exchanger
- leaking manifolds
- leaking heat exchangers
Symptoms of water flow issues:
- overheated, burnt heat exchangers
- leaking manifolds
- boiling / banging / whistling of the heater
Symptoms of air supply issues:
- blocked condensate tank
- damaged heat exchanger fins
- damaged firebox insulation
- damaged blower assembly
Many issues can almost be put down to "bad luck." It is best to have one of our technicians assess your heater on-site.
MX 125 thru 500 Issues:
MX heaters, being based on older Minimax heaters, were a basically robust burning system.
Early models were let down by plastic manifolds that warped, and a mild steel tube end plate. Poor water quality accelerated corrosion and warping. We see many MX heaters that have leaked over time. It's best to have these assessed in person.
