Controller shows E16 and the generator shuts down shortly after starting, often with white smoke.

Safety first: Turn OFF the generator and disconnect the battery. Allow the engine to cool before opening the airbox.

• Remove and inspect air filter: Open the air filter housing and remove the element. If it is heavily soiled, wet, or damaged, replace it with the correct DuroStar filter.
• Check airbox and ducts: Inspect the airbox for leaves, nests, or debris. Clean thoroughly. Follow the intake duct to ensure it is not crushed or blocked.
• Inspect enclosure vents: Make sure the generator housing intake vents are clear of snow, dust, or obstructions. Maintain required clearance around the unit.
• Test run without filter (briefly): For diagnosis only, run the engine for a few seconds without the filter to see if it runs smoothly. Do not operate under load or for extended periods without a filter.
• Reinstall new filter: Install a new air filter and secure the housing. Clear E16 and test the generator under light load.
