New pressure washer and MTM hydro foam.
 

After a bit of research, I decided to purchase an electric pressure washer, along w/ a foam cannon. I went w/ the Sunjoe SPX3000 and MTM hydro foam. One of the reasons I went w/ Sunjoe was it already has quick connects and seemed to have decent reviews.

My issue w/ the Sunjoe is w/ the water nozzle, when I spray, water comes out, but once in a while it stops spraying water and the pump keeps running even though my hand is off the trigger.

Anyone have any ideas what could be the cause?

Troubleshooting I've done:

Turn water on, keep pump off and spray. Sometimes I do see that the water stops momentarily and then comes out again. Maybe that is what is the cause, but I don't understand why the pump keeps running?
