Error Code E08: Fuel System Error, flame out error, Combustion chamber may need cleaning, Diagnosis and Resolution
Introduction:
Error Code E08 indicates a fuel system error in your heating system, signaling that no fuel is reaching the heater for the glow plug ignition. This guide offers comprehensive insights into potential causes and instructs on how to diagnose and resolve the E08 error.
Initial Priming:
If you’ve recently installed your heater and encounter the E08 error, it may be due to insufficient priming. Ensure that you prime the heater before its first use and every time you run out of fuel. Adequate priming is essential to establish a fuel flow from the tank to the heater.
Fuel Tank Level:
Running out of fuel can trigger the E08 error. Confirm that your fuel tank has enough fuel, especially if your heater is connected to your van’s fuel tank. Ensure the standpipe reaches the bottom of the tank to avoid issues when parked with a quarter tank or less.
Air Bubbles in Fuel Line:
Air bubbles or pockets in the fuel line can cause the E08 error. Driving with low fuel and the heater running can introduce air into the line. Ensure the pump is not pulsing when the standpipe is not fully submerged and maintain the heater side of the pump at a minimum 45-degree angle upwards.
Fuel Line Leaks:
Check for fuel line leaks, as they can prevent fuel from reaching the heater. Tighten all fuel line clips and inspect for any signs of dripping. Address any leaks promptly.
Green Soft Fuel Line Issues:
The green soft fuel line, often supplied with these heaters, can be problematic. It is prone to introducing air bubbles into the fuel lines during pump pulsing. Opt for the rigid nylon type instead to avoid air bubble-related errors and potential over priming.
Pump Angle and Kinking:
Ensure that the pump’s angle is at least 45 degrees upwards to prevent the introduction of air bubbles. Additionally, be cautious of kinks in the fuel line, as they can restrict fuel flow and lead to the E08 error.
Cleaning Recommended:
Conclusion:
Error Code E08 can have multiple causes, ranging from priming issues to fuel line problems. By following these diagnostic steps and avoiding the soft green fuel line, you can address the E08 error effectively, ensuring a consistent and reliable operation of your heating system. If uncertainties persist, consider consulting with professionals for further guidance and resolution.
