As a supplier of silent diesel generator sets, I often encounter customers who are troubled by error codes on their generators. Error codes can be a source of frustration, but understanding how to reset them can save you time and money. In this blog post, I'll guide you through the process of resetting error codes on a silent diesel generator set.
Understanding Error Codes
Before we dive into the reset process, it's important to understand what error codes mean. Error codes are messages generated by the generator's control system to indicate a problem. These codes can range from minor issues, such as a low oil level, to more serious problems, like an overheating engine. Each error code corresponds to a specific problem, and the generator's manual will provide a detailed explanation of what each code means.
Common Error Codes and Their Causes
Here are some common error codes you might encounter on a silent diesel generator set and their possible causes:


- Low Oil Pressure: This error code indicates that the oil pressure in the engine is below the recommended level. It could be due to a leak, a clogged oil filter, or a malfunctioning oil pump.
- High Water Temperature: This code means that the engine's coolant temperature is too high. It could be caused by a malfunctioning cooling system, a low coolant level, or a blocked radiator.
- Overload: If the generator is overloaded, it will display an overload error code. This can happen if you're trying to power too many devices at once or if there's a short circuit in the electrical system.
- Battery Charging Fault: This error code indicates that the battery is not charging properly. It could be due to a faulty alternator, a loose battery connection, or a dead battery.
How to Reset Error Codes
Now that you understand what error codes mean, let's look at how to reset them. The process of resetting error codes can vary depending on the make and model of your generator, but here are the general steps:
- Identify the Error Code: Refer to the generator's manual to find out what the error code means. This will help you determine the cause of the problem.
- Address the Problem: Once you've identified the cause of the error, take the necessary steps to fix it. For example, if the error code indicates a low oil level, add oil to the engine. If it's an overload error, reduce the load on the generator.
- Reset the Error Code: After you've fixed the problem, you can reset the error code. Most generators have a reset button or a sequence of buttons that you need to press to clear the error code. Refer to the generator's manual for specific instructions on how to reset the error code.
Step-by-Step Guide to Resetting Error Codes
Here's a step-by-step guide to resetting error codes on a typical silent diesel generator set:
- Turn Off the Generator: Before you start the reset process, make sure the generator is turned off and disconnected from any electrical devices.
- Locate the Control Panel: The control panel is usually located on the front or side of the generator. It contains the buttons and indicators for controlling the generator and displaying error codes.
- Find the Reset Button: Look for a button labeled "Reset" or "Clear" on the control panel. If there's no dedicated reset button, you might need to press a combination of buttons to reset the error code. Refer to the generator's manual for specific instructions.
- Press the Reset Button: Once you've located the reset button, press it and hold it for a few seconds. The error code should disappear from the display.
- Check the Generator: After resetting the error code, start the generator and check if it's running properly. If the error code reappears, it means there's still a problem that needs to be addressed.
Tips for Resetting Error Codes
Here are some tips to help you reset error codes on your silent diesel generator set:
- Read the Manual: The generator's manual is your best resource for understanding error codes and how to reset them. Make sure you read the manual carefully before attempting to reset the error code.
- Use a Multimeter: If you're not sure what the error code means or how to fix the problem, you can use a multimeter to test the electrical system. A multimeter can help you identify issues such as low voltage, high resistance, or a short circuit.
- Seek Professional Help: If you're unable to reset the error code or if you're not comfortable working on the generator, it's best to seek professional help. A qualified technician can diagnose the problem and fix it for you.
