Troubleshooting failed MiSeq system checks
Note: For how to perform a MiSeq system check, see Knowledge Base article How to perform a System Check on the MiSeq.
The MiSeq system checks are comprised of four tests: motion, optics, thermal ramp, and fluidics.
The tests listed under the Illumina Use Only column include the Tip/Tilt and Full Optics tests. These tests require a beaded flow cell to complete successfully. Therefore, Illumina Service Engineers carry a beaded flow cell for performing these tests.
For failed tests, power cycle the instrument, perform a maintenance wash with water and repeat the system check with an alternate flow cell. Contact Illumina Technical Support for any repeated failures or further questions.
