Having problems with your Pressure Washers ?

I have a Husky gasoline pressure washer. The honda motor starts but stalls because the pressure by-pass (not the right term) doesn't seem to open and builds up pressure. I haven't tried to remove any parts yet. I think grit has got in but don't know for sure. The pump looks pretty simple and the part I want to remove for cleaning looks like a plastic hexagon nob. Will this access the by-pass or is it something else.


Answers :

I think you're right about the knob, but try this:
Open the water to the washer. Leave the line open, and hold the trigger down to get all of the air out of the supply and discharge lines. While still holding the trigger down on the spray gun, crank the engine. This works in effect, like a pressure by-pass, and may free up the bypass valve. If you let off of the trigger, you may have a problem getting your flow back if the bypass is still stuck. You can repeat the above process and perform your work.

I recently purchased a Dewalt DXPW 3835 Pressure Washer from Home Depot.... After 4 hours use I no longer get any pressure. After depressing the trigger, I get a second of pressure and then it just dies. I called DeWalt and they couldn't help and to take it to the Warranty Shop. They informed that they wouldn't be able to look at for 2 weeks so I took it back to HD and got a new one and this one does the same thing. I'm pretty sure it's probably a pretty quick fix but no one seems able to te

I ran my pressure washer today in an effort to run some "stabilized" gas through it for the winter. For some reason the pump began to push oil out the top relief hole. If thats not clear, it's a feature that looks like a priming pump but is rigid. By the way, the oil appeared a bit nourish gray. Not sure if that means anything. Any ideas?


It looks as if moisture/water has contaminated the oil. Check the level of oil from the glass window. It must be high. Drain out the oil & check if water is present, if so then replace the entire oil. ... Dewalt DPD3100 Gas Pressure Washer

Model 01902 2350 psi . engine runs fine , sprays out nozzle but lower pressure and water sprays out plastic elbow on relief valve , that is supose to **** in soap if used , cant hold finger over spray from elbow , high pressure , took apart relief valve and plastic valves all orings are ok , brass pump seals look ok , all back together , still blows out elbow . ?? plastic spools were out by somebody else , not sure if they are in right , cant find picture to compare .


It sounds as if the non return valve in the elbow is the wrong way around .The o-ring normally goes in first then the ball then the spring. Try it and good luck. ... Pressure Washers

Troy-Bilt 2550 20293 pressure washer not producing pressure. Worked when last used 2 months ago. Pump pistons are moving up and down when engine is pulled through. Inlet water is flowing through pump but no pressure when engine is started. I have the same problem. Water flows thru the pump when not running, but no flow or goes in by-pass mode when I start the pump. The pump being Troy Bilt Model 020296-01. I replaced unloader valve even. Anything else I can do?


You replaced the unloaded valve. Are you positive you have the unloader screwed to pressure and not turned the opposite way? You will have no pressure if it is adjusted wrong. One other thing I have encountered is that the unloader has a ball bearing ... Pressure Washers

Low Pressure with no hose attached, pressure is good, attach hose without wand and pressure drops 50%. Have had pump apart 10 times, have checked bypass valve, have even removed bypass and filled passage way so water could not bypass wihout any change. Am down to thinking pump casting is cracked allowing bypassing to happen. Does each of the three piston chambers have a check valve so one piston is not pumping back into another piston chamber?

I can see the wash pump on the side and it looks easy to get at, but the drain pump looks a bit more of a mission. are you able to expand a little bit. Should i remove the rinse pump and check that it's not obstructed by anything maybe?

I have a pressure washer with a Honda gcv190 engine. The motor runs great but there isn't any water pressure. I removed the manifold and pump and found some mineral deposits and cleaned everything out and while attempting to reinstall the pump on the crankshaft I noticed the key was missing. Upon further inspection it appears that the key was missing from the beginning or had sheared off and then disintegrated. (There were a lot of metal shavings in the pump shaft recess).

Bosch dishwasher SHX46A05UC/40 is making noise when draining. I have cleaned the screen and hose back to the drain and removed all debris. So it seem to be the 'drain pump'. But replacing it - now that seem complex - is it? Looks like I would have to stand the DW on its head and remove the base and then replace the pump. Anyone know if I am on the right track? Could it be something else?
