Glad to see the engineers.

Where are we wrong? I understand what you're saying, but most people aren't engineers or thinking in technical terms. If the average guy gets a shovel of powder ten minutes after it falls, then gets a shovel full after a 35° day in the sun, he's going to say it got heavier.

Don;

Replacement guns are cheap at Northern Tool and other places. Your gun is probably stuck with minerals in the water?

No, I have fixed the switch 20+ by unscrewing it pulling the tiny plunger and putting lube on it. It will work for a few weeks before it gets stuck again.
This time the tiny plunger in the switch is stuck and no longer moves freely with the pressure change when the gun trigger is released turning the machine off.

Terminology help needed.

What do you call the switch on a pressure washer that is connected right before the hose connection and turns the pressure washer on when the trigger is pulled and shuts the pressure washer off when the trigger is released.

That automatic switch is sticking bad, the machine cuts off and will not come back on until I unscrew the switch and pull the plunger out. I want to get a new one but I can't seem to find it using the phrase "automatic pressure on/off switch". I think I'm using the wrong words and the manual is no help.
Unloader. But it may be the gun.

I think it's called a "doo-hickey."

You are about as good as me, but I got a little further calling it a flow switch, but still no image that looks anything like the switch I have.

Unloader valve.

Unloader valve.

None of the unloader valves look right. Here is a picture of the switch. it is unscrewed from the black part so you can see the spring that is around the little plunger.

When I turn let go of the trigger on the gun the pressure in the valve goes up pushes the plunger in (toward the white box) which turns the electric off of the pressure washer. The opposite when the trigger on the gun is depressed.

Try "Flow actuated switch". See if that gives you the results your looking for.

I'd buy the new gun. They aren't real expensive.

Must be different than mine. Mine uses unloader valve to remove pressure to wand hose when you stop spraying. When it sticks, won't allow pressure go to wand.
