Common Issues
Check if the gas supply is turned on. Ensure the water inlet filter is clean. Verify that the power supply is connected. Inspect the thermostat settings for proper adjustment. Look for any error codes on the display.
Examine the water flow rate. A low flow rate can cause temperature changes. Clean the water inlet filter if dirty. Ensure the thermostat is set correctly. Check for proper ventilation around the heater. Inspect the gas pressure to make sure it’s stable.
Refer to the user manual for specific error codes. Each code indicates a different issue. Error Code 1 usually means a flame failure. Error Code 2 often indicates a low gas pressure. Error Code 3 may point to a water flow sensor problem. Follow the recommended steps to fix each error.
Initial Checks
Check power supply and gas connection first. Ensure the water flow rate meets the heater’s requirements. Inspect for any error codes on the display.
Power Supply
Make sure the heater is plugged in. Check if the circuit breaker is on. Ensure the fuse is not blown. Verify the power outlet is working. Use another device to check the outlet.
Gas Supply
Ensure the gas valve is open. Check the gas line for leaks. Use a soapy water solution to spot bubbles. Make sure the gas pressure is within the recommended range. Use a pressure gauge for accuracy.
Water Flow
Confirm the water inlet valve is open. Check for blockages in the water line. Clean the water filter if necessary. Ensure the water pressure is adequate. Use a pressure gauge to measure it.
Error Code Diagnostics
Error codes help identify problems. Each code points to a specific issue. Error Code E1 means the water flow is low. Error Code E2 indicates a temperature sensor fault. Error Code E3 shows a problem with the fan. Error Code E4 means there is a combustion issue. These codes make troubleshooting easier.
Resetting the system can fix minor issues. First, turn off the power. Wait for 10 seconds. Turn the power back on. Check if the error code is gone. If not, consult the manual. A reset often clears temporary glitches. Always ensure safety while resetting.

Maintenance Tips
Turn off the water heater before cleaning. Remove the filter cover carefully. Clean the filter with water. Use a soft brush for any stuck debris. Ensure the filter is fully dry before reinstallation. A clean filter ensures efficient heating. Repeat this process monthly.
Check all connections for leaks. Tighten loose connections with a wrench. Look for any signs of wear or damage. Replace damaged parts immediately. Regular inspection prevents water damage. Perform this check every three months.
Temperature Fluctuations
The thermostat controls the water heater’s temperature. Check the thermostat settings on your Girard tankless water heater. Ensure it is set to your desired temperature. Sometimes, resetting the thermostat can help fix fluctuations. Follow the manufacturer’s instructions for resetting.
The flow rate affects the water temperature. Ensure the flow rate is steady and not too high. A high flow rate may cause the heater to struggle. Adjust the flow rate to a lower setting if needed. This may help maintain a constant temperature.
No Hot Water
The gas valve might be the issue. First, turn off the power to the heater. Next, inspect the gas valve to ensure it is in the correct position. The valve should be open. Check for any leaks or damage around the valve. If the valve seems faulty, you may need to replace it.
The burners must be clean. Turn off the power and gas supply. Then, carefully remove the burners. Check for dirt, debris, or rust. Clean the burners using a soft brush. Reinstall the burners and turn on the power and gas. Test the water heater to see if it produces hot water.
Advanced Troubleshooting
The circuit board can cause problems. Always check for burnt components. Look for loose connections. Secure any loose wires. Replace the circuit board if damaged. Make sure to reset the system after fixing.
Sensors play a crucial role. Faulty sensors can disrupt heater operations. Inspect the temperature sensor first. Clean the sensor if dirty. Replace it if faulty. Check the flame sensor for dirt. Clean it gently with a cloth. Replace if cleaning doesn’t help.

When To Call A Professional
Some problems are too hard to fix alone. If your heater has strange sounds, call for help. Water that is too hot or cold can mean a big problem. Bad smells or smoke need a professional’s touch. Complex electrical issues should be left to experts.
Safety is very important. Always turn off the power before checking the heater. Never touch wires with wet hands. Gas leaks are dangerous and need immediate attention. Carbon monoxide can be deadly; get a professional if you suspect a leak. Safety gear like gloves and goggles can help protect you.
