Hello everyone!

After working fine for months, my Vevor 80w Machine is giving me a water error.
We had before a Pump on a bucket, now that is giving trouble, we try an extra chiller we have, but the error persists.
We are gonna try the chiller of the other laser that is working fine, if the error continues, we will assume the problem is not the Pump or the Chillers, water seems running well when we turn on, coming in/out the tube. the error is a constant beeping, red light on, no shown any error code.
Now, from everything I read, if the problem is neither the chiller nor laser tube, the problem can be the water flow sensor that supposedly goes from the laser to the mainboard. but we have been no able to locate it yet

Do any of you has changed that part before? I saw some online, but I want to make sure we can be located and get the same that is in the machine before I buy.

Thanks

Michael
