Troubleshooting the LO Code on Hayward Gas Heaters
If you’re facing the LO code on your Hayward gas heater, don’t worry, we’re here to help you troubleshoot and resolve the issue. Follow these steps to get your heater back up and running:
- Check the pump: Ensure that the pump is running smoothly and providing sufficient water flow to the heater. A malfunctioning pump can cause the LO code to appear. If you notice any issues with the pump, consider calling a professional for assistance.
- Inspect and clean the filters: Clogged or dirty filters can restrict water flow and trigger the LO code. Carefully remove and clean the filters, removing any debris or blockages. It’s essential to regularly clean and maintain your filters to prevent future issues.
- Reset the heater: If the LO code persists after checking the pump and filters, you can try resetting the heater. To do this, cycle the mode button on the control panel through the “STANDBY” mode and back to its original operating mode. This reset may help clear any temporary issues causing the LO code.
- Contact a professional: If the troubleshooting steps mentioned above don’t resolve the LO code error, it’s recommended to seek professional assistance. A qualified technician can diagnose the problem accurately and provide the necessary repairs or replacements.
Remember, safety should always be your top priority when dealing with gas heaters and electrical equipment.
