Pressure washers take the hard work out of a whole host of cleaning tasks by simply blasting out water through a jet to knock off dirt and grime from any surfaces.

You’ve most likely found your way to this article because you are trying to identify why your pressure washer won’t stop. Well there can be a variety of reasons to why this is happening. However fear not, we have investigated the most common causes which may have resulted in your machine constantly running.
