Water hose won't come off pressure washer

Hello Morris Daniels - Are the house valves fully turn on? Is the hose kinked or pinched? If not, then it sounds like you have an issue with the water pressure and possibly will need to replace the pressure switch. First try checking water pressure at another faucet in the house. Wait until water supply and pressure increase (water pressure for washer must be at a minimum of 30 psi). Straighten the water inlet hose if it is twisted or kinked. If any proves to be ineffective, contact a professional to move forward accurately.

sounds like you have a blockage maybe in your water hose ,ideally your water hose should be around 25 feet..or you may have an o ring in the gun where the tip goes.. is broken..that will affect your pressure..check also filter where water hose connects to the pump make sure thats clear

They work on a pressure switch. It has a rubber hose that connects to the bottom of the drum and runs up to the top control panel. When water fills up into the hose the air pressure trips a switch. So either the switch is bad and not making contact when it clicks. Or the hose is leaking air so it won't let it build up enough pressure. I had one that a mouse got up into and chewed a hole in the hose. You can take the back panel off of the top control panel and let the water in and listen to see if the switch clicks when it gets fulll. If it does and doesn't stop filling then it is a switch.
Or it could be the water shutoff switch where the water hoses hook up. If it is that then it will run all the time, more than likely. Is that what it is doing? Does the washer start running and water keeps coming in? Because it wont start running until the pressure switch is enganged. If it starts running and keeps coming in it is that. Good luck hope this helps.

Turn the water on, hold trigger down and let water run thru the hose to prime the air out of the hose. If it still will not start check the spark plug and clean it or replace it. A bad spark plug will keep it from starting

Hi

If the washer won't fill you'll need to check for the water inlet hose, the water inlet valve and the pressure/water level switch assembly. Inspect the inlet hose coming to the washer for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the pressure/water level switch assembly should be replaced. Hope this helps... Please post back if you need more information.

Is there a lot of water inside like more than normal? That is a pressure sensor error. Check pressure hose inside the washer. It is a small hose about 5/16" diameter connected to the tub and pressure switch. If there's a hole in it the air scape and the pressure switch will not turn off the water. The control board detects the problem and stop will show error code.

• F-20 means no water or insufficient water supply, or at least this is what the washer "thinks."

1. Make sure the water for hot and cold are both on and functioning properly without any kinks.
2. Turn the water off and remove the hoses from the back of the washer and check the screens on the inlets on the back of the washer. Over time they can become crusted from mineral deposits etc.
3. To much detergent can prevent the washer from detecting incoming water from "to many suds."
4. Make sure the water pressure is sufficient. If the pressure is to low some washers just won't function right.
5. Some hoses have flood preventing inlets that will close if the hose gets to much pressure through them shutting the washer down.
6. After you fix what you think is wrong you need to unplug the washer for two minute so it can reset and then plug it back in.
7. Sometimes after this code is fixed and reset and a new cycle is choose for the first time after being fixed the washer will drain out completely. This is normal.
8. If non of these things fix the problem you could have issues with the control board, flow meter or water level pressure switch.

• Hope this helps and thank you for using FixYa.

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:

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.
