Why doesn't it work when the water hose is attached?


Pressure washers can only be started/run with water attached. No water burned out pump in 5 seconds! If pump puts out high pressure water without wand/hose attached, bad wand or hose, if not bad pump. Replace pump.

The water pump is pretty much shot! Did you crank the pressure washer without the water being on? Most times you see this when this occurs.

I have lost the pressure of water but the motor is still working.


If the motor was ran without the water being attached to the washer it would crack the pistons which is what creates the water pressure for you.

Cant pull start the pressure washer


Turn water off to the pressure washer, release pressure by applying hand pressure to sprayer. After water pressure is released, turn water back on (should not have motor running without water.) then try to pull start.

Engine runs , not getting any water flow when trigger pressed.


Disconnect hoses.
Look for kink in water hose.
Check incoming water connection for filter washer
Replace filter washer
If you don't have a filter washer, put one in.
Hook up water, and turn on
Water should come out other side of pump.
Turn on machine.
Do you get pressured water out of pump.
If no pressure, then pump is suspect
Hook up washer hose without gun
Does pressure come out of washer hose
Finally, the gun trigger may be bad.

We had to buy guns now and then.
Search for pressure washer guns
Following link shows guns we used:

Water goes thru. have hydrulic oil to level. gun semas to stick on. NOT GETTING ANY PRESSURE AT NOSSEL.


Hydraulic oil?
Is this a pressure washer?
Pump should be half full of SAE20 or SAE30 non-detergent motor oil.
Engine should have 10W30 motor oil.

If you have a pressure washer ... and not water is coming out end of gun:
Take all hoses off machine.
Look at incoming water hose connection.
The should be a filter washer.
Clean or replace filter washer.
Hook up water and turn on water.
Water should come out other side of pump.
Turn on power washer and see if water coming out of pump is pressurized.
Now hook up pressure hose without gun.
Turn on pressure washer and see if water comes out of hose and is pressurized.
Finally, the gun may be bad.
We used to replace guns when they went bad.

Engine runs. No water thru hose. Pressure valve(???) underneath has water coming out of it


Sounds like bad seals. But first take the hose off and see if water comes out the outlet without the hose there.
