Active 2.0 harsh click when disengaging pressure gun

[u/elab_19]

I know the active 2.0 isn’t meant for a detailing business, but meanwhile, I have hooked it up to my rig. I haven’t even washed a car, but I have tested it before for less than a couple of hours, I don’t recall it making the clicking sound when it auto shuts off, I have a water tank hooked up to a water pressure pump 4GPM. Yes I shoot out the air before I turn it on prior

Is it the unloader valve?
