An oxygen concentrator is a vital device for individuals needing supplemental oxygen therapy. These devices, often used for home care, are complex machines that use Pressure Swing Adsorption (PSA) technology to separate oxygen from other gases in the air. Understanding the error codes on an oxygen concentrator for home use can be essential for proper maintenance and ensuring uninterrupted oxygen delivery. In this article, we’ll explore common error codes and troubleshooting steps, helping you get the most out of your oxygen-making machine.

How Does an Oxygen Concentrator Work?
Before diving into error codes, it’s essential to understand how an oxygen concentrator works. Unlike oxygen cylinders that store compressed oxygen, oxygen concentrators pull in ambient air and use molecular sieves to extract oxygen. This process enables continuous oxygen production, ideal for long-term use in home settings. Most models feature various alarms and error codes to indicate issues affecting oxygen concentration or machine performance.
Common Oxygen Concentrator Error Codes and Their Meanings
Oxygen concentrators are designed to alert users with error codes if there’s a problem. Here are some of the common error codes and what they indicate:
1. E01 – Low Oxygen Output
What it Means: This code typically indicates that the oxygen concentration is below the acceptable range, which could mean the oxygen machine is not producing enough oxygen.
Troubleshooting: Check for blocked filters or low power. Cleaning or replacing filters often resolves this issue. Ensure the device is running in an environment with sufficient ventilation to avoid restricted airflow.
2. E02 – Low Pressure Warning
What it Means: This code indicates that the pressure inside the concentrator is lower than the required level (below 20kPa).
Troubleshooting: This could be caused by obstructions in the air intake or humidifier bottle. Clean the air filters and inspect the tubing for any kinks or blockages. If the issue persists, contact the manufacturer or a professional technician for further assistance.
3. E03 – Low Voltage
What it Means: If the voltage supplied to the oxygen concentrator is below the standard, the device may display an E03 error code.
Troubleshooting: Ensure that the concentrator is plugged into a stable power outlet with the correct voltage requirements. If the error remains, try another power source or consult an electrician to stabilize the voltage supply.
4. E05 – High Pressure Warning
What it Means: This error indicates that the internal pressure of the concentrator has exceeded safe limits (above 260kPa), potentially due to clogged filters or tubing.
Troubleshooting: Inspect all filters and ensure they’re free of dust and debris. Check the tubing and connection points for any blockages. If clearing the airways doesn’t resolve the issue, contact a qualified technician.
5. E35 – Overheating Warning
What it Means: When the oxygen concentrator’s internal temperature exceeds 70°C, an E35 error may appear.
Troubleshooting: Ensure that the device is in a well-ventilated area away from direct sunlight and sources of heat. Avoid placing it on soft surfaces, like a bed or sofa, which can restrict airflow.
6. E31 – Oxygen Sensor Communication Error
What it Means: This code appears when the concentrator is unable to communicate with its oxygen sensor, which could affect oxygen purity levels.
Troubleshooting: Verify that all cables are properly connected and that the sensor is not damaged. If the problem continues, contact the manufacturer for a replacement sensor.
Preventative Measures for Error-Free Operation
To reduce the occurrence of error codes and ensure your oxygen concentrator operates efficiently, follow these preventative measures:
Regular Filter Cleaning: Dust and impurities can clog filters, causing low oxygen output or pressure issues. Clean the filters every month or as recommended by the manufacturer.
Proper Placement: Keep the oxygen concentrator in a well-ventilated area with at least 15 cm of clearance from walls or furniture. Avoid placing it near humidifiers or sources of smoke.
Power Supply: Use a reliable power source to avoid voltage fluctuations. If power instability is common, consider using a voltage stabiliser.
What are the Common Faults in an Oxygen Concentrator?
Oxygen concentrators, though highly reliable, can occasionally face technical issues due to regular wear, environmental factors, or improper maintenance. Understanding these common faults can help users maintain their devices effectively. Here are some typical problems that may arise in an oxygen concentrator for home use:
Low Oxygen Concentration: This occurs when the device fails to produce the required oxygen purity, often due to clogged filters or blocked tubing. Regular filter cleaning can usually prevent this fault.
Air Pressure Issues: Oxygen concentrators require a certain internal pressure to function effectively. Low pressure may occur due to blockages, while high pressure can be a result of restricted airflow. Both can trigger warning codes on the machine.
Power and Voltage Fluctuations: Oxygen concentrators require stable power. Power surges, low voltage, or improper outlets can lead to operational errors or even damage to the device.
Overheating: Prolonged use without proper ventilation can cause the concentrator to overheat, potentially affecting its performance and triggering safety alarms. Ensure the device is placed in a cool, ventilated area.
Sensor Failures: Some oxygen concentrators are equipped with sensors to monitor oxygen purity. Sensor communication failures may lead to inaccurate readings, requiring sensor inspection or replacement.
Routine maintenance, following the manufacturer’s recommendations, and recognizing these common faults can help users manage their oxygen machine effectively, reducing downtime and enhancing safety.
When to Seek Professional Help
If troubleshooting steps don’t resolve the error code, it’s essential to consult a professional or the manufacturer. DIY repairs may void the warranty and could risk further damage. Some parts, like molecular sieves, may require specialised attention if performance declines.
Oxygen Concentrator Uses and Benefits
Knowing how to handle issues with your oxygen concentrator enhances its benefits, especially for individuals with chronic respiratory conditions like COPD. This oxygen machine provides a continuous supply of pure oxygen, supporting vital bodily functions and reducing fatigue. Its various uses include oxygen therapy for the elderly, people with cardiovascular issues, and even those recovering from physical or mental strain.
Choosing an Oxygen Concentrator for Home Use
When selecting an oxygen concentrator for home use, consider key factors such as flow rate, portability, and ease of maintenance. Devices like the Konsung KSOC series offer error code systems and alarms, which help with early detection of potential issues. Choosing a reliable brand that provides clear error codes, an efficient oxygen sensor, and a long-lasting compressor can make a big difference in performance and peace of mind.
Final Thoughts on Oxygen Concentrator Error Codes
Understanding and responding promptly to oxygen concentrator error codes is essential for anyone relying on these devices for daily health needs. By following preventive care steps and knowing when to seek help, you can ensure your oxygen-making machine operates smoothly and efficiently. Whether you refer to it as an oxygen concentrator, O2 concentrator, or oxygen machine, regular maintenance is key to its long-term performance.
For those using or planning to use an oxygen concentrator at home, this knowledge can enhance device safety and reliability, offering a consistent supply of oxygen whenever it’s needed.
Frequently asked Questions
Q1. What does the E01 error code mean on an oxygen concentrator?
Answer: The E01 error code typically indicates low oxygen output, meaning the oxygen concentration is below the required level. This may be due to blocked filters, low power, or restricted airflow.
