Description
A large amount of fluid flow was detected when the gun was not turned on. This might be caused by the dump valve being stuck on, or a broken fitting, or a broken paint line. Note that each time the fluid begins to leak fast, the color valve will be turned off. This will prevent the robot from spraying the part.
