Fortunately, there are some troubleshooting steps you can take to get it up and running again. Let’s take a look.
Turning Off The Heater Power And Gas Supply
Before you do anything else, make sure that you turn off the power and gas supply to the heater. You don’t want to risk any accidents while you’re troubleshooting.
Checking And Cleaning The Filter And Pump
Dirty filters and pumps are common culprits for heater problems. Check to see if the filter needs cleaning or replacement, and whether the pump is clogged. A thorough cleaning can often solve the issue.

- Turn off the pump and clear any debris from the basket.
- If the pump is clogged, try flushing water through it to clear out any blockages.
Verifying Proper Gas Pressure
Ensuring proper gas pressure is critical for your heater’s operation. If the gas pressure is too low, the heater won’t function properly.

- If the gas pressure is low, check the gas line for any leaks or damage.

- Check the pilot light and spark electrode for any buildup or damage.
- Clean the pilot light and spark electrode if necessary.
- If cleaning doesn’t work, the pilot assembly may need replacing.
Reviewing The Thermostat And Pressure Switch
If you’ve gone down this route and still couldn’t fix the issue, it could be the thermostat or pressure switch that’s at fault.
- Check that there is no debris interfering with the pressure switch diaphragm.
- Ensure that the thermostat is accurately set and connected to the heater.

Performing A Reset Of The Heater
Finally, reset the heater to default settings. This will often successfully troubleshoot the issues with your equipment.
