Pressuer washer not turning on

The machine motor initially turned on and had pressure, but then the water hose blew. We put on another water hose and now can't get the machine to turn on. I've reset the switch and that doesn't seem to help. Any ideas?

Inside machine are safety switches, you probably have a stuck on. Take apart, plug in and test with a tester to see where power is not getting to. I am guessing a safety switch is stuck.

The initials FH keeeps comin up on screen when the wash is at 26 minutes Then I have to turn off power and press start button again. What do these initials stand for?


Hello,

The FH error code means the computer on the control board didnt detect any water entering the washer..sometimes it doesnt detect the water entering because the filter screens on the water inlet valve are clogged with sediment and water is having a hard time entering the washer.

The filter screens can be checked by turning off water at the faucets and disconnecting the fill hoses from the back of the machine and pop the screens out of where the hoses connect at the washer and check for blockage in them. If they are found to be clean, check the water coming out of the hoses before connecting them back to the washer...if the screens are clean and water pressure is good out of the hoses the part of the washer called the FLOW METER would need to be replaced

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.

My pressure washer is a G 2500 oh n i have no pressure coming out, it turns on but no pressure.


Good news, your engine runs
But your pump may be bad

Here's how to test your pump
Check oil as outlined lower down
Disconnect the washer hose and gun
Connect water hose and turn on water and water should pass straight through the pump
Look for clogs in the hose-end where water hose connects to machine

Turn on machine and see if water shoots out pump
If water shoots out of pump, but no water shoots out of gun, then you may have a 'mud-dobber' wasp clog in your washer line or gun

Look for clogs in the end of each water connection.
Now connect washer hose without the gun, tun on the machine, and see if water shoots out of washer hose
Finally, the gun trigger mechanism may be bad
I don't know which gun you have ... but we replaced guns on our machine now-and-then ... google-search power washer guns for a replacement

Check your pump oil
Pump oil is SAE20 or SAE30 non-detergent motor oil
Pump should be no more than 1/2 full of oil
Use plastic hose to drain pump oil
Do not turn machine on its side or turn machine over or engine oil will run into carburetor

Craftsman model 580.752020 electric pressure washer. First time I used it worked for about three minutes then the motor stopped. I cannot get it to start again. Plugged into a 15 amp gfi circuit which did...


turn off water and machine electrics.

remove high pressure hose from front of machine, this may be tight if there is still pressure in the system.
turn on water, when water comes out of machine hose outlet turn on machine. does the machine turn on and water flow increase, if so you probably have a blocked lance jet or trigger.

remove lance extension if fitted and fit hose back to machine, try again. If its ok then this proves you have a blocked lance jet, maybea poke about with some stiff wire will free the obstruction.

If this doesnt bring on the machine you probably have a jammed pressure switch on the pump.

this pressure switch turns on the pump when the trigger is pulled and switches the motor off when the trigger is released.

hope this helps.

LF Code coming on during rinse cycle


Long Fill LF flashes when the water level does not change for a period of time after the valves are turned on OR water has disengaged the basket but control does not detect a water level change. • Is water supply connected and turned on? • Are hose screens plugged? • Is water entering the tub? If so check pressure hose connection to machine/motor control.

Karcher Power Washer that surges up and down with water pressure.


Before you start it up:
1. Disconnect the high pressure hose 2. Connect the water supply and turn on 3. Make sure water is flowing through the pump
Start the motor, run for about 10 seconds and then turn off.
Turn off the water supply, connect the high pressure hose, turn water back on, start the motor and away you go.

Pressure washer has no pressure


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!!

GE Washer-Doesn't Fill When it Supposed to.


It is most likely a pressure switch. This is the water level switch. As water fills the tub, air pressure builds up in the rubber hose going to the switch. When the pressure is high enough for the water level setting, it trips the switch and puts the unit in wash cycle. Remove the control and start the machine. While it is agitating, remove the hose from the switch and see if the washer starts filling. If so, blow through the hose and see if something has clogged it. If you have a volt/ohm meter you can check across the terminals while you blow into the switch to see if it is working. Let me know what you find out.
