THE ONLY ONE TO EXPLAIN IT PROPERLY SO I COULD CATCH HOW IT WORKED THANKYOU

I have a DeWalt 3400 pressure washer that did not have pressure. I originally thought the pump froze up. Found and watched this video and checked my unloader valve. It was stuck. I loosened it up and lubed it and reinstalled. Works great now. Thanks Chris! Saved me hundreds.

UPDATE:1 year and still cranks within the first 2-3 pulls. Probably will buy another when this one finally does bite the dust kzfaq.infoUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX . No issues at all. Very happy with it.UPDATE: After 6 months of use and over 70 uses I would still highly recommend this pressure washer. It does vibrate a decent amount but never had it “walk” like others have mentioned. No oil leaks, still seems to run like the day I bought it. Still cranks within 2-3 pulls every time. Very happy with my purchase!Have used it about a dozen times now. Plenty of power, cranks up on 1-2 pulls every time. My only complaint would be I wish it was a little taller to make it easier to walk with it (hits my ankles a lot) and that the two hose connections were a little further apart but it hasn’t caused me any issues. Seems to run a good 1-1/2-2 hrs on a full tank, overall a well built machine and definitely worth the money in my opinion.

Thanks a lot. I have a Stihl RB600 and my local shops didn't want to mess with it. I watched your video and you fixed it for me. Thank you!

Perfect video! I tried it right away on my washer and same problem. Now it is fixed. Thanks for taking time to make this video and help a fellow man!

Thank you. Only video I could find to solve my problem!!

How funny, I was born & raised in Kings Park. Right off of 25A at the Sunken Meadow Beach exit. Thank you for the informative video

He said to email the center for any questions you guys need to listen he is taking his time to teach us don't blow it

It sound like something is worn in the unloader that might be letting pressure pass through it and if it's leaking an oring maybe cracked. If you take it apart you may be able to replace the orings or you can purchase a new unloader.

I have a Lowes Power washer That built pressure and stalled I cleaned the loader valve made sure it worked and cleaned the little hole put it back together and it works like new. Thanks

Thanks Chris I learned a lot

Thanks for the video , what do you think of those FNA group AAA pumps ? Do you have trouble getting parts for them?

I'm having problems with the 2800 PSI at the pressure switch the Springs broke I want to know where the ball goes in first or the spring goes in then you bolt screws down with your plug to the office today

I just got a Ryobi RY802800 (I know, not the best, but it does have a Honda GVC Type 9 Engine). Anyway, I'm happy with it, but concerned that I might be over working it. I do give it a break between fueling, but otherwise it's under load all the time. It seems to me that keeping it under load 99% between fueling might make the the valves happier, but not so much the engine. What do you think?

could you show how to replace the water valves for the same pump

good job ,sir, chris

I'm your 1000th subscriber...making you money now! From huntington long island.

Thank you for the video 👍🏻👍🏻👏🏻👏🏻

Nice tutorial cris

My AAA pump on a DeWalt pressure washer has a problem with the ball bearing below the unloader part removed in this video sticking up in it's seat and the spring on the unloader removed cannot push it down when it should. I've had no luck getting the seat and ball out of the casting.

When its leaking between the head and crankcase with no pressure and what other material can i use beside ceramic

Thanks for the informative video. We have a Dewalt 3800 psi and looks very similar to this. Suddenly we aren’t getting any water thru it. Water in, no problem, but nothing out. May need to replace that same part

I have a Kohler 3000 series, used only couple hours if that, today after starting it, I felt that pulsating you described then water started jetting out of the seam between the copper head and the body of the pump, in the valve next to the unloader; no pressure out of the nozzle, all pressure was out of that seam as if it busted a seal. I took the copper head off but I don't know what I am looking at; the pump that comes with that pressure washer is an 8.7GA12 High Pressure Pump; I can not find it online or parts for it.

can you run a bypass hose from this kind of pump

how do you change the inlet where the water hose connects to the pump? and do you service pumps? i have one in california

Thanks Buddy!

Where can I buy one of these?

Where could orings be bought for the Simpson?

Hi Chris. I have a Honda GCV160 power washer. When I squeeze the trigger in the wand, the engine stalls. Do you know what’s wrong with my pressure washer?

Have Dewalt 3800 with 53003 pump much like in this video. Has been used only few times then pressure dropped to around 1/4 pressure and only minimal strain on engine when reaches that point . Installed new seal kit (no change) unloader seams fine ???

hi good night, i have the 3800 dewalt and the springs in my unloader damage and full of rust. how can i replace it???/

My washer locks up and consequencely is hard to start. It is also hard on the hand when pulling and the pump suddenly locks. What causes this? Do I need a new unloader cartridge?

what dose it mean when the motor engages but there is a delay in pressure ?

Have a simpson PS60841, have to keep the wand trigger pulled back all the time to keep it running. Took the unloader valve apart and replaced some o rings so as the spring loaded adjuster would slide back and forth. Then inside the port in the spot where the two orings are on the unloader valve is a small port that goes back to the discharge where you connect the hose for the wand. This small port was plugged, used a hobart tip cleaner which uses tiny drill bits. Found tip cleaner at Northern tool. Also used some .035 hard welding mig wire to clean out this small port. You will need a flash light to see it.

I have a craftsman 2400 psi and the only way I can keep it running is when the handle on the wand is pulled in once I release it,it stops running! Any help would be awesome

Hi, great video! I have the same model pump on my dewalt washer. Question? Can this model pump be bypassed with a return line to my tank? I having problems with my pump sometimes it chokes and won't pull water from May 100g water tank. Had the pressure washer for 6 months (new) but recently it's having this problem. Any help will be greatly appreciated. Thx!

Nice video!! I have a general pump T9211 pump.its 3000 PSI ,4.2 GPM pump.I am not able to get 3000 psi from it.I noticed water starts leaking out from the bypass at around 2400 psi doesn't matter how tight the adjustment screw is.My unloader is general pump zkhm.I tried to run the pump without the unloader and its producing 3000 psi at same rpms.Do you think my unloader needs any adjustment or should i get a new unloader?Thanks

I am have problems. My 3200 Roby will not pressure down when you let go of trigger. Runs fast all the time

I'm have problem with my honda gx390 pressure washer have no pressure .

Cheers Chris

when you check the other "check" valves what are you looking for exactly?

Kings Park baby!!! I lived there for 25 years!

Hey man.. I have a 4400 psi Simpson pressure washer (it’s the predator 420 cc motor & EZ 4040 pump ) My machine seems like it needs to push out 1,000-1,500 more psi Do you have any advice/recommendations for fixing this?

Whats the name of that part I accidentally broke half of it off

I have a pressure washer with honda motor, I didn't use it very often but last time I did, soonest I release the trigger on the gun the motor just shot off... So what I have to do it's just keep pushing the trigger all the time... Any idea what I can do? Thanks Raudel

Do you work on Landa pressure washers?

When you rebuild,, kinda,,, the uploader, don't you have to reset it with a gauged adapter, to make sure it's set properly? Thanks, good video.

hi I have a karcher pressure washer HD7 11-4M all running well but hose and pressure gage flicking when I trigger the gun and pulsing.any Idea? many thanks

hello I have a Sears Craftsman power sprayer. I left over winter in my garage when I finally got a chance to use it water shot out the front of it once I started the unit up. I don't know what's going on?

Hi, enjoyed your video! Can you tell me the size of the hex wrench key used to remove the 3 hex screws near the unloader? Is it 9mm or 3/8”? Thanks!

Tengo una maquina dewalt de 4000 psi y la bomba AAA 53brd35 tiro el aceite con agua por la parte del nivel de aceite Que puede ser el problema ?

I thought it was replaced under warranty ? You put the same one on with lube ?

When I pull the trigger there is pressure but if I keep the trigger pulled the pressure dies. Is this also an unloader problem?

I have a problem with my washer... It's vibrating a lot and the pressure has reduced by half.. What could be the problem ?

Does anyone know the size of the metal ball that he describes at 2:28 min. into the video?

Wow

I have a dewalt witch the valve seems fine but no pressure still, what else can be the reason?

I rebuild mine and now it wont pick up the soap or solution

Thanks. Very helpful! and remember, Jesus Loves you!!

My powerwasher is working with pressure one minute and none the next. Anyone any ideas what the problem is?
