SOURCE: No pressure in the pressure washer

Leaving the hose on shouldn't cause a problem so don't panic. It sounds like you could just have a dirty nozzle. Try sticking a pin or something in the end of the nozzle (machine not running) and giving it a clear out. also if it is a two peice gun, split it and tap the squirting part on something clean like a workbench to clear any debris that might have got in there.

SOURCE: I have the Coleman powermate 2400 PSI pressure

Sounds like the valve in the handle is sticking closed. May have a broken spring, or maybe a part is stuck..
I say take it apart, and the answer will present itself.. Play with it with nozzle out too... Maybe something is stuck after storing so long and will loosen up.. Fingers crossed

Coleman 2400 PSI Pressure Washer - WATER LEAKS OUT = ?!? Help me please!!! ((-:


Usually, there are spaces between the pump and head portion of the pump. This space is not sealed and will allow water leaking past the seals to come out. There may be a seal kit available, however I have had better luck just changing out the whole pump. There are many available on ebay. Search for one that will use same mount and hoses. Once the seals are gone, the pump will never be the same (may nickle and dime you the death).

I bought a honda pressure washer power boss 3000. I load the gasoline, start the machine, but pressure water is not coming out from the trigger. i tried so many things , but can t get started.


If you are using a water tank for water supply, remove the water supply line from the pressure washer and connect a water hose from a faucet. Turn the water on, then crank the engine. Pull the trigger of the spray gun until water comes out. When then water starts to spray properly the release the trigger, shut engine down with pressure on the line then reconnect the water supply from the tank to the pressure washer. If this fixes the problem then the problem was "air-locked"! Happens alot with new pressure washers that have never been run. If you need any other help, please email me @ davidandlisacampbell@yahoo.com

Sprayer will not stop pumping when switched to pump mode after primed it will not shut down it just keeps pumping. .


Paint sprayer.
Flip lever down to prime > paint comes out small plastic hose.
Flip lever up to put pressure on spray line.

Problem: prime keeps running and spray line never gets pressure.

Future solution:
You did not clean sprayer very well last time, or it is rusted. When cleaning, run full 5 gallons of cleaner through machine twice.
You should fill spray line and pump with kerosene if machine sits idle more than few days.
We all forget.

Good news: you have prime. If machine doesn't prime, you probably have to disassemble.

More good news: There are two steel balls inside pump. Tap top one with hammer to loosen. Keep machine running. Keep lever up. Start tapping top one. Tap a little harder... keep tapping ... sometimes it will not free up ... take apart pipe and see if you can nudge ball loose >> be careful not to scratch anything... the sprayer is high pressure and all parts have to fit

My Husky HU 80709 gas pressure washer starts (most of the time) but if I shut it off to answer a phone call, etc.,I cannot get it started again. It's like it has a vapor lock or something. Any ideas what...


I have the same power washer.
When you go to restart it you need to hold the sprayer nozzle so the their is no pressure in the hose. It is even better if you take the tip off the spray nozzle and then while holding the spray nozzle open restart. It will start up real quick. I never start it now with the hose on or attached at least from a cold start. Kind of a pain.
I will also tell you this. This morning I had two bolts shear off the main pump. I have used it 5 times and have had it only a year. I am hoping this is a fluke since I really do like the pressure washer. Jim

Not sprayer engine stop


This is an indication that the unloader not working properly. When you release the trigger the unloader senses the increase in pressure and bypasses the water into the water inlet. When the unloader is not working and you release the trigger, the water pressure builds quickly and overcomes the power of the engine shutting it down. Here is the manual for your machine, http://www.pressurewashersdirect.com/manuals/Simpson_WaterBlaster%20manual_2.pdf

and some information about troubleshooting from the manual.
"Not Unloading. Leak in Gunvalve or Hose. Repair gun leak . Replace leaking or broken hoses. Debris or wear in Check Valve. Remove Check Valve parts and clean. Check O-Ring. Reface with emery cloth, or replace checkvalve. Damaged Piston U-Cup. Rebuild Unloader Valve (Service Center)."
Usually when the unloader fails the pressure regulator will most likely need to be replaced as the unloader is usually incorporated within. For now try lowering the pressure some and just tie the trigger open untill you can service. Good luck.

Craftsman pressure washer constantly fluctuates and then stops


sounds like fuel problem. Either water\trash at bottom of tank, or most likely, carb needs to be disassembled and bowl and jets sprayed out w\carb cleaner.my money is on the latter.

STARTS AND RUNS FINE BUT WHEN I START WASHING IT QUITS SPRAYING AND THEN BUILDS PRESSURE AND KILLS ENGINE


The reason it stops spraying might be a clogged gun, hose or nozzle-tip.
The reason for pressure buildup killing the engine might be a stuck unloader valve in the pump.

While you are checking each component of the "output" side, spray some penetrating lube into the "input" side of the pump (where the garden hose connects) and let it be working on the unloader valve.

Fix the spraying problem first:
Start at the nozzle and verify that it is open by using low-pressure air. Clean or replace as needed. Next check the hose (with nozzle and gun unhooked) and finally the gun/trigger mechanism.
All must be clear and open to perform correctly.

Next, pour a few ounces of power steering fluid (or similarly LIGHT oil) into the garden hose, attach it to the pump and turn on the water supply.

Leave the "output" hose, gun, etc. UNHOOKED and point the output port of the pump (where the high-pressure hose connects) towards a vacant, safe area.
Startup the engine and allow the oil in the garden hose to work its way thru. (About 1 -3 minutes of run-time.) Shut it down and attach the high-pressure hose.
Hope this solves the problem!
