Pressure washer sprays water but not high pressure

When the power washer does not turn on, it is either due to no water flow or no electricity going to the power washer. In other words, either a water or electrical problem.
check water flow issue like this

1. The high pressure hose, spray gun and lance must be connected to the power washer.
2. The garden hose must be connected to the power washer using the garden hose adapter.
3. Turn the water completely on at the water faucet.
4. The power cord should not be plugged in.
5. Squeeze the trigger on the spray gun.
6. If there is water flow through the spray gun and lance shooting 10 - 25 feet, this confirms water flow is NOT the problem for the power washer not turning on.
7. If there is no water flow, perform the following troubleshooting procedures:
   a. Remove the lance, squeeze the trigger. If water flows, the lance is blocked. Use cleaning wire to clean the nozzle tip and try again.
   b. If no water flows with lance removed, turn the water off. Remove the spray gun from the high pressure hose. Turn the water on, if water flows, the gun is the problem. Reattach the gun, turn the water on and squeeze the trigger. Sometimes this unblocks the gun. If not, replace the spray gun.
   c. If no water flow with the gun removed, remove the high pressure hose, turn the water on to make sure there is no blockage in the hose. This is very unlikely but we need to make sure.
   d. If no water flows out of the water outlet, the quick connect garden hose adapter is problem. See Garden Hose Adapter troubleshooting.
8. For electrical solution check
9. The power switch was not turned on. Find the power switch and make sure the "-"side of the rocker switch is pushed down. "O" = Off and "¾" = On.
10. Next, make sure the power cord is plugged directly into an outlet and NOT into an extension cord. The directions do say not to use an extension cord.
11. Each time the power cord is plugged in to an outlet, the Reset button on the GFCI module must be pressed down to connect to electricity.
12. Check to see if the Reset button has been pressed.
13. Next, confirm the small plastic window below the Reset button shows RED in the window. The RED color is not a light but a RED screen that slides into the window when the Reset button is pressed down. Because it is not a light, it can be hard to see in low light. If you are unsure, press the TEST button down. If the GFCI was set and RED was in the window, you will hear and feel a "click."
14. The RED color must stay in the window once the button is released. This confirms there is electricity going to the power washer.
15. If the RED color goes away when the Reset button is released, there is NO electricity going to the unit. Try another outlet until the RED stays in the window.
16. Now if the unit turns ON for a second or two with the Reset button pressed and the power switched on, it is working as it should. All that is left to do at this point is to squeeze the trigger on the spray gun and the power washer will turn on. When the trigger is released, the power washer will turn off. This is due to the Total Stop System (TSS) that only turns the unit on when water is flowing through the power washer. When the trigger is released, water flow stops which the TSS sensed and immediately shuts the unit off. a) So to review, if the Reset button has been pressed and is holding and the power switch is ON, the power washer is supposed to start up for a second or two and immediately shut off. At this point all you need to do is squeeze the trigger; the unit will turn on.

This is normal. The high-pressure car washer has certain dangers. If the water column of his spray gun is aimed at people, it will stab people. If the switch is turned on and spray water, then the pressure of the spray gun head will be sprayed around, which will accidentally hurt people. people, so it's designed this way.

Maybe bad pump. Remove wand and wand hose, run machine with water in. High pressure water coming out of wand/hose connection, bad wand or hose. No high pressure water, bad pump, replace.

Check the hose and nozzle to see if it has any debris in it.

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 @ [email protected]

that is sure signal of insufficient water supply!

try easy solution first:
make sure that your mains is fully open, that tap on whihc hose is hook up is fully open and hose is of "decent" diameter to allow sufficient flow.

if above solution do not work then you need to make another, more difficult arrangement:
prepare 20litres pressure tank with inlet connected to mains and outlet by short hose to power washer, fill it with water from mains, keep it under mains pressure and use karcher power washer normaly. this will solve water supply problem. twenty litres will last about 2min, because it is re-filled, under standard pressure therefore it will last about 3min...

third possibility is to stop washing...

if you find my advice helpfull, please do not hesitate to left the comment and vote for me, thanx!

When I use my machine I hook up the water to the pump, hook up the high pressure line and gun, then turn on the water full and squeeze the triger to make sure all air is out before starting the pressure washer(mine is gasoline powered). Then I install the nozel on the spray gun. If you are having surgeing water pressure Check the hose washer where the water hose hooks to the machine, and be sure the supply hose is not restricted and valve is on full.

NorthStar Pressure Washer Turbo Nozzle --> --> Turbo nozzle sprays up to 3.1 GPM at 2300 PSI and 194°F. Unique design delivers 0° high pressure impact with wide angle spray coverage.
The point of the Turbo is that it is a solid ( high pressure stream of water )

this can happen if you use the wrong soap, you must use pressure washer cleaner, it does not foam.

Can anyone Solve this? My simoniz S2500 gas powered pressure washer has low pressure coming right from the outlet. It used to be high pressure until now.. I think it has something to do with the pump and if so, is there anything I can do to repair this problem? The screen is good; water comes out of the hose good, wand is ok......Just that lower pressure is at the wand even at high settings....It comes in a form of a spray in both modes......
