What's the rating on gun? Sounds like the gallon per minute volume may be too great.

Stanley motorised pressure washer. Cant get the water to flow


Disconnect the wand from the washer if you get water coming out of the discharge, the problem is in your wand or the line is plugged going to the wand.

My pressure washer will not gain pressure. What will cause this problem?


Make sure water supply is ok, make sure screen is clean, try all the different tips, make sure they are seated correctly. Water should come out of the hand wand even if not under pressure, this shows the wand handle is working, so if water come out it's not the trigger handle. You can remove the wand hose, wand handle and see if there is any obstructions also.

This can also be a stuck check valve, you might need to have it serviced.

Black and decker electric power washer nothing coming out of wand all water coming out trigger.


Either the pressure tip or wand are blocked or the valve in the trigger is broken. Remove the high pressure tip and either try another tip or pull the trigger without a tip on the wand to see if you have the same problem. If available, try another pressure gun on the hose.

As soon as I turn the water on, it comes out of the gun and high pressure turbo wand even with the machine off. I used it yesterday with no problems. It does this without even pressing the trigger. ...


Hello,
This part should be available from the manufacture, have you check their website. It is normal when you turn the water on for a small string of water to come out the gun when you press the trigger even when the engine is not running.
Thanks

My Snap-On 2000 PSI pressure washer is leaking through the trigger handle. I have no pressure coming out of the wand but the motor runs.


The fitting for the trigger is cracked. It happened to mine because I did not make sure the wand and hose was drained before winter came. The water left in the wand expanded and cracked the trigger housing. The problem is that the trigger piece is easily replaceable, but it is not available. Alltrade makes you buy the complete wand.

Hi, W/D here.
Leave the water on, and hold the trigger down for about 5 minutes to get all of the air out of the system. Letting off of the trigger occasionally and then opening it up will help displace any air in the chambers. While still holding the trigger down, start the washer. Should put up your desired pressure.
Best regards, --W/D--

Shuts off when high pressure wand is attached


Hi Brian. Welcome to FixYa I am Kelly. This sounds as if the bypass / unloader valve is stuck in place and the pump id dead heading causing the unit to shut off. (There is most likely some corrosion in the unloader / bypassy valve assy / housing. What you can try is pouring at least 3 oz of oil into the water inlet assy and briefly.... like VERY briefly switch the unit on then back off. Then let it sit over night. The next day connect everything for normal use then turn the unit on again briefly. Use a bucket to PURGE the oil that you put through the system by squeezing the wand Power SW Off until the oil purges. Then switch the unit on and rapidly trip the trigger at 0.5 sec intervals or less. If it trips off wait 5 mins and try it again. Do the rapidly tripping the trigger on the wand routine for about 20 seconds. Your forcing the bypass unloader valve to cycle trying to clear out any debris / corrosion.
This works often and well. There are exceptions. Hopefully it will work for you.

Thanks for using FixYa.

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!
