Regular filter cleaning is essential for the water heater. First, turn off the power and water supply. Locate the filter and remove it carefully. Rinse the filter under running water to remove debris. If the filter is very dirty, soak it in a mild detergent solution. Rinse thoroughly and let it dry completely. Reinstall the filter and turn the power back on. Check the heater to ensure it works correctly.
Inspecting Components
Inspecting components of a Girard tankless water heater ensures efficient performance and quick identification of issues. Regular checks can prevent unexpected breakdowns and extend the heater’s lifespan.
Burner
The burner needs to be clean. Dirt can block the burner. This will stop it from working. Use a soft brush. Gently clean the burner. Look for any cracks or damage. Replace if damaged.
Heat Exchanger
Check the heat exchanger for leaks. Leaks can cause problems. Clean the heat exchanger. Use a descaling solution. This removes any build-up. Make sure it is dry before use.
Sensors
Sensors are very important. They must work well. Check each sensor. Make sure they are clean. Dirty sensors give false readings. This can cause the heater to malfunction. Replace any broken sensors.
Addressing Error Codes
Error Code E1 indicates an ignition failure. Start by checking the gas supply. Make sure the valve is open. Next, look at the gas line connections. Tighten them if they are loose. Clean the burner and igniter. Sometimes, dirt can block them. If the problem persists, call a professional technician.
Error Code E5 means overheating. First, turn off the heater. Let it cool down. Check the water flow rate. It might be too low. Clean the water filter. Blocked filters can cause overheating. Ensure the venting system is clear. Blocked vents can trap heat. If the issue continues, contact a certified technician.
Error Code E7 signals a fan motor problem. Check the fan motor connections. They should be secure. Clean the fan blades. Dust can make them stick. Listen for any strange noises. If you hear any, the motor might be faulty. Replace it if necessary. For further help, consult a professional technician.
