Kubota code E9120: Fuel filter water warning

What it means

On Kubota SVL/SSV track loaders, E:9120 means water has been detected in the fuel filter (water separator). Kubota's table says to stop the engine, then check and drain the fuel filter.

Can I keep running?

Stop: fix before running

No. Stop the machine safely (bucket or attachment down, engine off) and find the cause before you run it again.

Check first

  1. Park on level ground, lower the loader, attachment or implement to the ground, set the parking brake, stop the engine and remove the key.
  2. Drain the water separator into a container as the operator's manual shows. No smoking or open flame near fuel.
  3. In freezing weather, check for ice in the separator bowl.
  4. Restart and confirm the code clears. If it returns, check the fuel and tank for water.

Likely causes

  • Water in the fuel or condensation in the tank
  • Machine stored a long time
  • Ice in the separator in freezing weather

The fix

Draining the separator clears it. If water keeps showing up, the fuel or tank is contaminated and needs draining, plus a new filter. Don't run with water in the fuel.
