No pressure!! when i turn on my pressure washer no pressure comes out of it why is that?

I'm guessing that you have a small electric washer. These come on when triggered.....or if there is a water leak on the high pressure outlet side, at a connector or the gun itself...or possibly some internal leak. It's not likely being worth the cost of a repair if it is something beyond a simple leak. Commonly, the washer will only come on in short pulses. Coming on and staying on would be an internal switch problem unless your high pressure leak is substantial. Leaks are usually just worn, split or missing o-rings at the connectors.

Hello,

The F1 error means that water pressure into the washer is out of range...the control on the washer learns the water pressure coming in from when it was brand new it is capable of learning just the water pressure to your house since it will vary from your neighbors...after it has learned what the normal pressure is if it doesnt see that normal pressure coming into the washer it will throw up the F1 error code

What to check is if water is coming into the washer from the rubber fill hoses with as much pressure as always did...things that could cause lesser pressure is; kinked/crushed fill hose,sediment built up in the filter screens inside of the water inlet valve( can be checked by turning off water and removing hoses and pop screen out from the back of washer where the hoses connect to)


If the filter screens are clear and water seems to coming from the hoses with good pressure...the washer control board would need to be replaced

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]

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:
http://www.ultimatewasher.com/pressure-washer-trigger-guns.htm

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.

Hold the trigger of the pressure nozzle open. Turn on the water . Wait to see water coming out of the pressure wand.Then try and start the engine. They can get air locked.

You should dismantle and clean the manifold from the pump , it is sticking. Common

Try and back flush the washer..Take spay nozzle off washer and back flush with hose...If any kind of sand or deposits get into the Pump it will hold pressure valve open not letting it build pressure.after back flushing hook back up washer and before you put spar nozzle back on or start washer turn water on and make sure all air is out of washer..hook spray nozzle back up and hold it open with washer still off.when you see that there is no more air coming out of washer start it and you should have pressure.Hope this helps you and have a great day!!
