Potential causes and fixes:
Battery Terminal Corrosion:
Cause: If your Bosch laser receiver has been submerged in water, the battery contacts and sometimes the circuit board may have corroded.
Fix:
Remove the batteries and clean the battery terminal contacts.
Pry open the bottom cover and clean any corrosion on the circuit board.
Calibration Issues (for Bosch GLL 2-20):
Cause: Dropping the Bosch GLL 2-20 can lead to misalignment and errors.
Fix:
The best way to address this problem is to calibrate the laser level.
You can either contact the Bosch service center or follow the calibration instructions in the manual.
General steps for calibrating a laser level with a misaligned pendulum:
Remove the screws and outer cover.
Locate the pendulum hanging in its stationary position.
Remove the glass window of the laser level.
Adjust the stationary position of the hanging pendulum using the main adjustment screw.
Fine-tune right-left adjustments using other smaller adjustment screws.
Reassemble the laser level.
Cracked Glass Lens (for Bosch GLL 2-50):
Cause: If the horizontal glass lens is cracked, it affects accuracy and safety.
Fix:
Unfortunately, this problem is often unrepairable.
It's advisable to replace the laser level to ensure safe operation1.
Remember to lock your laser level when not in use or during transportation to prevent pendulum movement1. If these steps don't resolve the issue, consider reaching out to Bosch for professional assistance or repair

That is the main bearing worn with so much play that a heavy load will stop it going around and normal wash will grind from time to time.
Bosch use very well made bearing so you might get more out of it before the bearing crashes completely.
