# Troubleshooting "Y Stage Initialization Error Operation home failed..." errors on the MiniSeq

MiniSeq Control Software fails to initialize with the following error:

* (33) Operation home failed due to flowcell\_y not being able to move to flowcell\_y\_home =1" and "(66) flowcell\_y stopped due to safety\_interlock"

This error may be the result of a communication issue on the MiniSeq. To troubleshoot, power cycle the MiniSeq.

To power cycle the MiniSeq:

* From the home screen, select **Manage Instrument**.
* Select **Shutdown Options**.
* Select **Shut Down** (this will shut down software and turn off instrument power).
* Wait 1-2 minutes before powering ON the instrument with the button on the front left of the instrument.
* Wait for the Windows operating system and MiniSeq Control Software to load completely.

If the error replicates after the power cycle, contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html#/united-states/technical-support) for the next steps.
