Common Causes
Faulty gas supply, improper venting, and electrical issues often lead to ignition failure in Navien tankless water heaters. Regular maintenance and timely inspections can help prevent these common problems.
Gas Supply Issues
A blocked gas line can cause ignition failure. Low gas pressure might also be the issue. Ensure the gas valve is open. Check for any leaks in the gas line. Proper gas flow is crucial.
Electrical Problems
Loose wiring can stop the heater from igniting. A faulty thermostat may also cause problems. Inspect the power supply for any interruptions. Ensure all connections are tight and secure. Electrical surges can damage components.
Component Failures
The ignition system can wear out over time. A faulty control board may not send signals correctly. The flame sensor might not detect the flame. Replace damaged components as needed. Regular maintenance can prevent failures.
Initial Checks
Ensure the gas supply to your Navien tankless water heater is open and adequate. Check for any error codes displayed on the unit. Verify that the electrical connections are secure and the circuit breaker is not tripped.
Power Supply
Make sure the water heater is plugged in. Check if the circuit breaker is not tripped. Confirm that the outlet has power using another device. Inspect the power cord for any damages. All connections should be secure. The display panel should light up.
Gas Valve
Ensure the gas valve is open. Verify that the gas supply is not interrupted. Check for any leaks around the valve. The gas line should be connected properly. Inspect the gas line for kinks or blockages. A steady gas flow is necessary.
Control Panel
Look at the control panel for any error codes. Press the reset button to see if it resolves the issue. Ensure that the settings are correct. The temperature should not be too low. Inspect the panel for moisture or damage. A functioning control panel is crucial.
Gas Supply Troubles
Experiencing ignition failure with your Navien tankless water heater? This common issue often stems from gas supply troubles. Ensure proper maintenance to avoid disruptions in hot water availability.
Gas Pressure
Gas pressure plays a key role in your heater’s performance. Low gas pressure can cause ignition issues. High gas pressure can damage the unit. Regularly check the pressure to avoid problems.
Gas Line Blockages
Blockages in the gas line can prevent gas flow. Dirt, debris, or rust can cause these blockages. Cleaning the gas line helps maintain smooth gas flow. A clear gas line ensures the heater works well.
Regulator Malfunctions
The regulator controls the gas flow. A faulty regulator can disrupt gas supply. Check the regulator for any signs of wear. Replace the regulator if it malfunctions. A good regulator ensures proper gas flow.

Electrical Concerns
Navien tankless water heater ignition failure often stems from gas supply issues or faulty ignition components. Addressing these concerns promptly ensures efficient performance and prevents further complications.
Wiring Connections
Check all wiring connections for tightness. Loose wires can cause ignition failure. Ensure that no wires are frayed or damaged. Replace any faulty wires immediately.
Fuse Inspection
Inspect the fuse for signs of burning or damage. A blown fuse can stop the heater from working. Replace the fuse if necessary. Always use a fuse with the correct rating.
Circuit Breaker Status
Ensure the circuit breaker is in the “on” position. A tripped breaker can stop electricity flow. Reset the breaker if it is tripped. Contact an electrician if the breaker trips again.
Component Inspection
The igniter must be clean and free of debris. Dirt can block the spark. Check for cracks or damage. Replace if it looks worn. Ensure the igniter is properly aligned.
The flame sensor should not be dirty. Clean it with a soft cloth. Look for signs of wear. Replace if necessary. It helps detect a flame. A dirty sensor can cause ignition failure.
The air filter must be clean. Dirt blocks airflow. This can stop ignition. Check the filter regularly. Clean or replace as needed. A clean filter ensures proper operation.
