If the unit has been stored you need to remove the bottom three plugs on inlet side of pump head and simply free the checkvalves that are in closed position needle nose recommended and small screwdriver to pry them open this is caused by the impurites in water that dry up and seals the head and disc together:):)

SOURCE: pump on my pressure washer will not pressuerize

there is a loader and unloader valve on your pump bolted to it. if it frozen in the open position it will never build press. most of the time this is caused by leaving cleaning solutions in system after use and let set up for a long period. it causes the aluminum case to corrode.;you will have to dissassemble and clean if not to bad. if not your going to have to replace.

SOURCE: Ex-Cell VR2500 Builds Pressure but Won't Spray

I have a similar problem and diagnosed it to be a problem with the gun. I spoke to a technician that services this pressure washer and he walked me through all the diagnostic steps. The pump is working because there is pressure being built up and the gun sort of works because you can get water out before the washer is started. The technician said that the mechanism inside the gun is either clogged or broken. I am going to Home Depot or Lowes to purchase a new gun and will try it tonight. Guns are only about $30-40. He said generic is fine as long as the thread matches and PSI is in range. Good luck!

Why is there no water flow through on pressure washer?


Sounds like a pump failure. Does yours freeze in winter? Need to winterize like cabin plumbing.
Repair/replacement of pump could be close to new unit.

I have a 3000 psi campbell hausfeld gas pressure washer and it has no pressue how can i fix it


Small stream sounds like your pump is not working at all - you are getting house pressure only. First check the intake fitting where you attach the hose for debris that may be clogging the water flow. Same for the pressure hose and quick connect fittings. Remove the tip from the wand and see how much flow you get. If it's still only a small amount, with the motor running, you probably have a bad pump. This can be caused by bad seals inside the pump, or by running the motor without maintaining water supply to the pump, which can melt the seals or even seize the pump if allowed for too long. Repairing the pump is typically more work and expense than replacing it, assuming you can locate a replacement pump.

WHEN YOU RUN OUT OF GAS IT WILL CAUSE FUEL PUMP DAMAGE CAUSING IT TO OVERHEAT.CHECK FUEL PRESSURE IT SHOULD BE 41 - 47 PSI. IF NOT REPLACE FUEL FILTER.IF FUEL PRESSURE STILL LOW OR 0 . FUEL PUMP BAD.

Power Washer has no pressure, any ideas


1. If you have an inlet chemical injection valve make sure that the hose is intact and that the valve is closed.
2. Purge all air from the line by holding the nozzle actuation lever open until all air has been purged. When you connect the water supply hose turn it on before connecting the high pressure hose and let the unit self purge to the pump outlet high pressure hose fitting. Then connect the high pressure hose.
3. You could have a stuck spring and ball inside the high pressure head of the pump. You can tip the unit on its' side and add a substantial amount of WD-40 to the water supply hose fitting in an attempt to free the springs and balls.
4. Try BRIEFLY running the unit without the hose connected to see if there is high pressure water ejected from the high pressure fitting.
5. Inlet water screen at hose connection is clogged (hose screen and rubber) Check screen for debris.
6. The water strainer is clogged. (Almost looks like an LPG regulator just after but in line of the supply hose connection to the pump)

Order of troubleshooting

1, 2, 5, 6, 4, then 3.

Thanks for using FixYa!

No water coming out of the pump


Hi
Is the pump working?
Some pressure washers need to suck the water out of a container, not pressure fed from a hose.
Check the filter for blockage.

COMPRESSOR PUMPS UP TO 40-50 psi KEEPS RUNNING.


Most likely the pump is leaking somewhere, if the new hose is not leaking. Hoses don't just burst without showing signs or wear and tear, i.e. cracking and splitting. The pump was probably having problems, and this caused the hose to burst. Look for signs of leakage, and if you can't find them, the pump is shot.
