Pressure Washer HELP!


#1

Hey I just bought a new Simpson 4200 psi professional pressure washer and I started it up and was running fine until when I let off of the trigger the whole pressure washer SHUTS down completely and I need to know I how to fix this because I have to do a pressure washing job for a client on Friday. Thank for help

Did it trigger a shutdown from low oil?


#3

If the engine sounded like it was struggling right before it quit, it’s more than likely your unloader.
More information please.


#4

No it is full of oil


#5

The engine didn’t sound like it was struggling at all and I don’t think it could’ve been from the unloaded because it’s brand new


#6

How about gas


#7

Yes sir more than half way


#8

Is the water on


#9

Not trying to be a clown, but is the gas shutoff valve open? If yes, gas shutoff could be faulty. I don’t have good luck with poly valves.


#10

I had an unloader with less than 5 hours on it take a dump.
How many times did this happen?
Was it for sure every time you let off the trigger, or was it a coincidence?
What happened when you tried to restart?


#11

Yea it is flowing out when I pull the trigger


#12

Is the flux capacitor in tack?


#13

Oops. Just reread it. The little tiny unloader on the thing goes bad. I had the same machine except a dewalt awhile back it did the same thing to me. It’s bet a can of Grizzly it’s the unloader.


#14

Mine does not have that feature


#15

O so I don’t know much about unloaders but it is already bad? I just bought it two days ago?


#16

Yes it is


#17

Hate to tell ya, but that AR pump is not a good pump. It’s got a tiny little valve that releases pressure if don’t pull the trigger for awhile.

It would not surprise me in the least if it came to you bad.


#18

I’m with @NewGuy89 Doug. I’d be willing to bet the unloader was stillborn.


#19

O shoot, I’m 16 with my own little business and I have a job lined up on Friday so I don’t have anymore money to spend on a new pressure washer so what do you think I should do?

Did you buy it local?
