I purchased an Ender 3 V3 Plus about three weeks ago. TOday after printing a Temp tower, I started another print and noticed the printer had not started moving. The Creality Print Window had an error message and when I checked the Touchscreen, it said CL2529 Level Sensor may experience external interference. I stopped the print and tried to Home the Z axis. I noticed that the Z axis wouldn’t get closer than about an inch from the print bed.
I checked the console in FluidUI and there is an error message, !! {‘code’: ‘key529’, ‘msg’: ‘PR_ERR_CODE_G28_Z_DETECTION_TIMEOUT: G28 Z try probe out of times.’, ‘values’: }

It sounds like a software issue, maybe try an downgrade firmware installation?
Thanks CalvinBVN , I did upgrade the FW over the weekend because it advertised that the CP6 g-code issues were fixed. The printer would work off and on aver the past few days. Sometimes with the error sometimes flawlessly. If it were a true hardware issue, I believe I would be SOL. I am at 3.23, so I just rolled back to 3.21. Fingers crossed.
Same here!!
Initially, my Ender 3 V3 Plus created a good bed mesh after calibration using firmware version 1.2.3.21. However, after upgrading to firmware version 1.2.3.23, I noticed a calibration issue. The hotend would no longer lower all the way to the bed. Instead, it would often stop about 1 cm above the bed and move up and down several times without making contact. Occasionally, it would stop with an error message stating that the hotend might be experiencing external interference.
After rolling back to firmware version 1.2.3.21, I was able to calibrate the bed mesh properly again, but the interference error message still occurred occasionally. In such cases, I simply turn the printer off and back on.

I also get error CL2529 on my Ender 3 V3 (no suffix… what a terrible naming scheme).
I dismiss it on the touchscreen each time with no trouble so far. Does anyone know where the level sensor is on the printer?
After rolling back to 1.2.3.21, I have not had the error return and printer is working great. Four separate prints, long and short with zero issues.
After several power cycles, I am experiencing the same issue with version 1.2.3.21. In about one out of four attempts, the calibration completes successfully. However, in the other cases, the calibration results in errors.
The issue starts during the nozzle cleaning process. The hotend does not fully lower to the bed. Instead, the nozzle moves up and down slightly several times without touching the bed. Following this, it extrudes filament into the air rather than onto the bed.
How can I resolve this problem?
I am having the same problem, mine also makes this juttering noise when its lowering, i don’t know if that’s normal.
