E002High Engine TemperatureCooling system failure; low coolant
E003Over-speed ConditionGovernor malfunction; load issues
E004Battery Voltage LowDead battery; charging system issue
E005Fuel Level LowTank empty; fuel line obstruction

Solutions for Common Doosan Generator Fault Codes

Understanding the underlying issues is crucial for effective troubleshooting. Here are some practical suggestions for the common codes listed above:

  • E001 - Low Oil Pressure

    • Solution: Check oil levels and top off if needed. Inspect the oil pump and oil pressure sensor for faults.
  • E002 - High Engine Temperature

    • Solution: Inspect the coolant levels and the radiator for blockages. Ensure the cooling fan is functioning properly.
  • E003 - Over-speed Condition

    • Solution: Assess the generator’s load. Calibrate the governor settings if necessary to prevent further issues.
  • E004 - Battery Voltage Low

    • Solution: Test the battery with a multimeter to check voltage. If low, consider recharging or replacing the battery. Inspect the wiring of the charging system.
  • E005 - Fuel Level Low
