Title: Small Engine/Pressure Washer Repair S. King Co.
Post by: Fl0und3rz on August 05, 2018, 05:12:35 PM: Anyone know a good place to take a pressure washer that is acting up?

It is on the pump end of things. Tips are welcome, but in all likelihood, I will not have time to repair it myself.

Symptoms were low pressure, until it appeared the pressure regulator or unloader "unstuck," then it operated great, if uneven and surging pressure, until finally, it just seems to operate with the unloader completely open.

I have the model number and parts source, but I would hate to just throw parts at it without determining it was the proper fix.

Thank you.

This was the initial symptom, then it freed up and worked for a while, and while it freed up the crusties, there was a lot of surging in pressure.

One thing the manual (and various internet TSR guides) says that I dismissed was to check the suction screen for clogs. Me being incredulous, I dismissed this after recalling that I have never seen a screen clog from municipal water. What do you know? I checked, and it was about 50% clogged. It ran fine (relatively except for the unloader sticking) in the morning as water pressure is typically higher until use over the day lowers my line pressure. Then in the afternoon, that seemed to be enough to cause the later in the day issue I was experiencing (low/no pressure).

I cleaned out the screen, purged the lines of air, and it ran fine to finish up the job (steady pressure, too) for about 20 minutes.

This guy was helpful as he reinforced to check lines for obstructions.

Thanks for all the replies.
