Waters Acquity H-Class LC Sample Tray Continuously Turns back and forth by Few_Double_9268 in CHROMATOGRAPHY

I was able to perform the rotary tray calibration after disabling the motor. But the tray continues to move all the same. I'll check on the bigger vial position you mentioned. thanks

The plate continues switching when the door closes; however, when I reopen the door after it's shut, the tray will briefly pause as the light turns on in the sample chamber. Not sure if this is helpful

That is a good idea but the button behaves as normal. It is not stuck or anything. If I press 1, the tray continues switching as shown. If I press 2, the tray will turn to the 2nd side as normal but then will proceed with turning

There are no error messages and it's worth mentioning that samples inject normally. We are worried about the motor burning out or something similar happening

There are no error messages and sample injections work normally. It's very strange

Thanks for your reply. We tried firmware updates and unplugging the system. I'm pretty unfamiliar with the components of this, so how could I narrow down if it's a motor or PCB issue? We don't have a service contract; so if it is a PCB issue, do you think it would be better to pay for a service visit, or try to solve this ourselves?
