Eppendorf Centrifuge 5424 R Service Manual Jun 2026

Regular user maintenance is the first line of defense against equipment failure.

If the unit was exposed to hazardous samples, it must be thoroughly decontaminated. Fill out a Decontamination Certificate before performing service.

Check the drive assembly for blockage. A technician may need to check the PCB Control/Converter. Lid lock failure

If the set temperature (+4°C, for example) does not match the actual sample temperature, the refrigeration system needs calibration.

Centrifuges store immense kinetic and thermal energy. Adhere strictly to these rules before opening the chassis:

Check and empty the condensation water tray located at the rear of the unit. Monthly/Long-Term Maintenance Eppendorf Centrifuge 5424 R Service Manual

Whether you are an in-house biomedical engineer, a laboratory manager, or a technician troubleshooting an error code, understanding the service protocols of the 5424 R ensures equipment longevity and user safety. 1. Safety First: Pre-Service Requirements

The motor is not reaching the set speed. Potential PCB or drive failure.

He turned the rotor by hand. The multimeter beeped. Open. Short. Open. Short.

Chapter 4: Error Code F01 – Overspeed . The manual was not flowery. It had the personality of a guillotine. “Cause: The Hall effect sensor monitoring rotor velocity has failed or is obstructed by debris. Consequence: Safety interlock prevents rotor engagement.”

Defective drive motor, failing inverter board, or a blocked rotor. Check the drive assembly for blockage

Misaligned microswitches or a faulty lid latch motor.

The Eppendorf Centrifuge 5424 R is a versatile, refrigerated centrifuge designed for a wide range of laboratory applications, including molecular biology, cell culture, and clinical research. It features a compact design, high-speed capabilities, and advanced safety features, making it an ideal choice for laboratories with limited space. The centrifuge is equipped with a powerful refrigeration system, allowing for precise temperature control and ensuring the integrity of sensitive samples.

Rapid cooling function ("FastTemp") and continuous cooling when not in use.

| Error Code | Symptom / Message | Typical Cause | Recommended Remedy | | :--- | :--- | :--- | :--- | | | Lid cannot be locked. | User error. | Try to close the centrifuge lid again. | | LID ERROR | Lid cannot be released. | Software glitch. | Switch device off and on again, then press the open key. If error persists, use the emergency lid release. | | LID LIFT (5424 R) | Lid not opened wide enough. | Mechanical obstruction. | Open the centrifuge lid wider by hand. | | NO RPM | Error in speed measuring system. | Electronic glitch. | Leave the device switched on for 10 seconds or up to 6 minutes until the error clears. | | Err 6 | Drive error / Drive overheated. | Overload or thermal event. | Repeat the run. If error reoccurs, power cycle after >20s. For overheating, allow drive to cool for ≥15min. | | Err 7 | Deviation in speed control. | Rotor not tightened. | Wait for rotor stop, then tighten the rotor firmly. | | Err 9–17 | Electronic system error. | Electronics. | Switch the centrifuge off and back on after >20 seconds. | | Err 18 (5424 R) | High temperature variation. | Airflow blocked / ice buildup. | Check vents and settings. Thaw ice or switch off to cool down. | | Err 19, 24 (5424 R) | Cooling circuit overheated / fault. | Poor ventilation / overheating. | Check air circulation, clear vents, and allow unit to cool down. | | Err 20, 21 (5424 R) | Temperature sensor faulty. | Hardware failure. | Power cycle the centrifuge after >20 seconds. If error persists, contact service. | | Shaking on Startup | Imbalance. | Rotor loaded asymmetrically. | Stop, reload symmetrically, and restart the device. |
