Kipor controller shows E11 and the generator shuts down shortly after starting

Safety first: Turn OFF the generator, disconnect battery negative, and allow engine to cool. Avoid skin contact with used oil.

• Step 1 – Confirm actual oil level: Use the dipstick to verify that oil is at the correct level. If low, top up with the recommended oil grade and clear any leaks.
• Step 2 – Locate oil level sensor: On many Kipor engines, the oil level float switch is mounted in the oil pan or side of the crankcase. Disconnect its connector and inspect for corrosion or oil intrusion.
• Step 3 – Test sensor: With the sensor removed (if possible), move the float by hand and check continuity with a multimeter. Replace the sensor if it does not change state as the float moves.
• Step 4 – Clean sludge: If the float is stuck due to sludge, clean the area and consider performing an oil and filter change. Use only oil meeting Kipor specifications to reduce foaming and deposits.
