Fault Phenomenon: Dynapac F300W paver instrument displays fuel water contamination, engine power limited.

Troubleshooting Process:
– Checked fuel-water separator: excessive water in bowl.
– Checked sensor: water level sensor float stuck.
– Checked fuel: poor quality fuel from filling station.
– Checked tank: water settled at tank bottom.

Root Cause: Excessive water accumulation in the fuel-water separator triggered the sensor, or water was not drained in time, allowing moisture to enter the high-pressure common rail system.

Required Parts: Drain water from fuel-water separator, replace fuel filter.
