My pressure switch itself was stuck not the valve! I was bummed when cleaning the valve didnt work so i opened up the switch and actuated it a few times with a flathead to make sure it worked while plugged in. It worked as it should so i put it back together and to my surprise everything functioned as it should. Thanks for your help
Just fixed my greenworks with this. I was very close to suplexing this machine off the top rope because the repetitive on off sound was so annoying. Thank you again for saving my ears and mental health 👍
THIS IS EXACTLY WHATS WRONG WITH MINE WAS NOT SURE FROM THE FIRST 40 SECONDS IF THIS FIX WOULD WORK IM SO HAPPY (Got a $650 active 2.3 in my cart im still buying tho LOL)
I've gone through several of these over the years when the "died" from these exact symptoms. When it happened again I figured it had to be something I could do. This worked INSTANTLY. I can't thank you enough !
Great video! Superb sound, camera angles and lighting. Zero wasted time with intros and whatnot. Really appreciate the knowledge you shared and the hard work it takes to make a good video like this! Now off to fix my RY1900...
@@DakotaBusy Just finished! Cleaned off a wee bit of crud, sprayed on some o-ring safe silicone spray and bam, good as new! I bought a few of these sold as store-returns to resell thinking it was just the notorious faulty wands that would be a problem (I replace them with some nice ones from the Zon). This has been the only one that wouldn't run, and was worried it might be seized. Owe you one!
I'm going through this repair right now. Great video, by the way. Thanks for not trying to be cute or funny, you just showed the DIY repair. Straight forward and to the point. Great job, and again, thank you!!!
Thanks for this video! It saved me a bunch of $$ by not (yet!) having to send my Ryobi 1600 PSI to a repair depot. It had just stopped working, and after having tested the power supply all to way to that pressure switch, that was the problem. But when I took it apart, it was pristine, no deposits, no debris, clean. And the switch appeared to be working exactly as it should have. After two full disassemblies and re-assemblies of that pressure detection mechanism, it somehow decided to work again, and seems to be OK now. Why, I may never know. Your video showed me the way, and I'm very grateful for that!
Thank you for your excellent video. I've looked in the manual for the solution and the manual gave no clue. Checked factory web--nothing. Emailed them--"go see a dealer". Nothing! You've done a great service for us!
Well done on the DIY video! I wish every video of this type provided the same balanced level of detail so that I can do it by memory when I head out to the garage. Thanks again!
You're a genius, this worked for mine. It didn't stop working but it would cycle when it is on but not spraying...like it would loose pressure. I cleaned what you mentioned and SUCCESS 🙌 thank you
I'm in a market for a pressure washer. I've had Ryobi home products in the past. It's my experience that they're cheaply made to last 3-5 years maximum and then you throw them away. My last pressure washer last several years of just occasional use. By my estimate it had a MTBF (Mean Time Between Failure) of about 30 hours. Use for 30 total hours over the course of several years and throw it out.
electrics should last longer than gas because people run the gas engine without water flowing through the system. Electrics shut off if you are not using it. Also, remember to drain and lubricate when putting away for more than 1 month. lubrication is critical to seals. yes designed to fail.
2021 here thank you for this video. I have a Black Max washer with the same problem. Cleaned out the valve, made sure that there was no blockage and once reinstalled everything worked. Thanks again
Thank you for the video. Mine was turning on and off and my valve was all corroded. I cleaned mine out for nothing and saved myself at minimum 120.00 for a new pressure washer. I used a wire wheel on a drill and greased up my orings with some hydraulic oil. It's all I had here. Works perfect.
I disassembled my greenworks 1500 psi valve body this evening and after I began to start to clean I was called inside for dinner - needless to say I'd forgotten what order the spring, washers, o-rings, etc. when back together. I actually "guessed" for re-assembly and tested - the washer works better than it has in the past - I found this video afterwards but wanted to say thank you! Great detail and suggestion about the socket - as I was watch I thought "I wonder if he'll use a socket like I did to get it together" - sure enough. Again, thanks for the detailed video - you saved me from buying a new washer and spending $100 when mine just needed the valve cleaned up...
Thanks for the video. I just did this to my 2000 psi model and its working again. Now i don't have to take it to a warranty repair shop and wait weeks for them to fix it.
Great video! My pressure washer was acting up. I removed the pressure switch and found a small back plastic piece lodged near the white rod thingy... cleaned it put it back and it worked great again.
Thanks for this video. Good job - filmed and explained very well. I was about to install a new pressure switch, and without your video I probably would have ignored this valve area. Who knows, good chance this could have been my problem all along! Oh well, live and learn .... die and forget it all!
Thanks for the tutorial! Was able to diagnose and fix ours. Not sure if you've seen it before, but a piece of solder had wedged itself at the bottom of the switch preventing the metal switch from moving! Thanks!
great video, had the pulsating problem and followed your advice, i also removed inlet u clamp where screen is and found build up and inlet clogged, unclogged and with both fixes machine worked like new, ty
Good information, I like the part, where I go buy another $70 pressure washer, mine engine turns on and off on its own. One day I can use it for 8 hrs, the next day nothing, wait 1-a3 days and it’s back for another 8hr. Thanks for the info
Great video, very clear except for one vital point (that applies on my model at least): The two washers are similar looking but if you mix the top and bottom one on the plunger, you'll never be able to correctly re-seat the valve assembly. You will watch this video and think this guy is Herculian-strengthed, when in reality you just mixed the washers up and the plunger won't correctly slide in the brass housing. You'll know you've got it the right way around because it actually doesn't require much force at all to compress the spring and seat it.
Two things, if the washer kicks off and you think you might have released the trigger. But do not think so this is a sign the micro switch is failing. Cost me $3.10 at Q kits in Kingston Canada they ship everywhere. If both green lights are on and no pumping action it is likely the micro switch. The micro switch can be replaced without taking the pressure valve apart. Just loosen the 4 screws of the cover to expose the switch..
Would this also fix this model of machine from turning off and on constantly, except when using the gun? As soon as I stop using the gun the pump cycles on and off constantly…no leaks visible. ~UPDATE~I tried this fix and replaced the o-rings while I was at it, and was successful. Likely a bad o-ring and gunk build up
This pump and switch is exactly like the Craftsman 1900psi washer. I wish I had seen this before I did all the things you said not to do. My spring and assembly went flying. 🤣🤬. Nothing really looked dirty, put back together, and it still cuts off and doesn't come back on. Also, you didn't mention, but there is another small o-ring that goes up in the switch housing on the white pin isn't there? Placed on top of the small hole washer before putting the switch on the valve.
Mine does the same thing. Works fine for 10 minutes then shuts off. Tried a new switch, still NG. If I shut off the water, remove the hose and water from the unit then reattach the hose, turn the hose on, press on switch, it works again. Then it will shut off again. Im not sure what the problem is. About to buy a new one.
Great video !, I had the opposite problem on my 2000psi, it would turn on, run up the pressure until it tripped my circuit breaker. No idea what the pressure hit, but I couldn't get the handle lever to open, the plastic bent but never opened the nozzle. The activator was seized down, never came up to flip switch
I-ring Size - anyone know the size of the o-ring that is at the bottom of the pressure switch, the one that the top of white plunger is pushed thru? All the parts websites don’t even list this o-ring, spring, plunger, or gold anodized aluminum, barrel.
So the brass piece was really gunked up, no issues with the spring shooting it up, couldn’t barely get it out and in my attempts to do so, I broke the tip of the white plastic piece that actuates the pressure switch 🥴. I can’t seem to find a replacement online, all the parts guides have everything but these. Do you have any recommendations where to get a replacement?
thanks great video. I took it apart, and SHOULD NOT HAVE, it was working fine. Broke the O-RING which is size. id=5/8. od=3/4. thickness=1/16. can buy 100 for $4 from amazon, but will try local hardware store 1 for $2. lesson learned leave alone what is working. trying to solve low pressure. it is a great pressure washer, will run forever when lubricated properly IF I CAN FIX low pressure. Will take pump apart next to see what I have. By low pressure, I mean maybe 400-600psi, and not 2,000 psi as expected. Any thoughts appreciated by viewers. ANYONE KNOW EFFECT OF O-RING being old cruddy and not working properly. If anyone knows, a reply would be great.
@@johnjkizer6399 I really appreciate you replying. Trying to size a new o-ring using my old, worn and stiff o-ring has been difficult. Three questions: Do you remember if the thickness of the new o-ring rubber was the same as your old o-ring? Did you have to push slightly the head of the plunger through the new o-ring when assembling? Did the new o-ring fit snuggly in the bottom of the pressure valve? Thx much!
I have a electric pressure washer that keeps stopping and starting with the trigger not pressed what could it be. I checked everything that you mentioned but it still does it, goes on and off. What does the mechanism look like on the high pressure side where the water comes out I'm not sure if I have trouble in there. I can't find any diagrams of exploded view. Any help would be very appreciated.
The spring can be a pain. I had luck using a socket to help me push down on parts to allow me to get the clip back in. The part you are pushing down has slots for the clip so it needs to be just in the right place. I've even used a hammer with light taps to get the clip to go back in.
Hi I broke the top of the brass aluminum fitting that goes over the spring and plunger. I checked ryobi parts but nothing do you know where to get that?
My spring only came with the bottom washer. The top of the spring seats directly in the brass housing. So I can hear the pump cycle on and off when I pull the trigger. But the water pressure is super weak. No kinks in the line or anything. Just can't figure it out.
I'm not sure either. If there are no obstructions or leaks maybe the pump itself is starting to fail? Maybe others can chime in if they have an idea of a fix.
I opened the actual pump and lost the 2 springs...have spent hours looking online for exploded diagram of the pump to find the part number if any for these springs, 1700 PSI
Hey. Thanks for the video. I have a Sunjo power washer. It just stopped running completely used last time fine then nothing. Tried replacing the plug nothing. Tried what you did here and nothing, one thing, when I toolk my switch off the spring did not pop or anything like that. What is frustrating is it makes no noise at all completely silent when plugging in. Any thoughts??
Thanks I thought I had it! Power went on fine. Hooked all up with sprayer, second I pulled trigger...........machine cut off. Green light on GFC and Green light on/off switch. so would it be isolated to the pressure switch? I have never soddered before.
Hola tengo un problema com la hidrolavadora ryobi de 2000 psi. El swiches del automático no me funciona q debo hacer hay lo desarmado varias veces. Y no acciona el swiches
I have the same pressure washer, and it is pulsing (pump frequently turning on/off) when the gun trigger is not pressed. Any ideas of what going on with it? Could I fix it by using your cleaning method? Thank you.
Usually a sticky valve would just make it not turn on at all. However, cleaning it wouldn't hurt. I would also check to make sure you don't have any leaks in any of the areas that have the high pressure. If water is leaking out somewhere it could drop the pressure enough to trigger the pump again.
I notice that Mine doesn’t stick out like that to get the switch to the off position , and I took it out clean it put everything together again and let the side cover off but I also notice that it doesn’t move at all . Any suggestions??
I tried this and it didn't work for me; the brass part was all rough and scarred some. I suspect it's causing a small pressure leak preventing it from being able to overcome the spring's tension. I can't find a replacement either so guess this thing is junk now :( I have a LOT of Ryobi tools. Some are great, others are not. Mostly their brushless battery power tools are good; not all but most. Their other stuff is hit or miss; for example the battery powered dremel is junk it has no power. But the small 80W inverter is good and the fan and lights are great. Guess their pressure washers are on the junk list, mainly cause there's no replacement parts for these valves and the pumps.
Really helpful video, thank you, it showed me what's wrong with my Greenworks 1600. Can you tell me the dimensions of that O-ring? I've got a Greenworks 1600 psi that looks exactly the same, but my O-ring sortof disintegrated (hopefully why the pressure switch isn't working), so I dont know what the right o-ring is. I have half of it, but I dont feel the pop when I insert the piston past the o-ring. Thanks!
I have a Power Stroke power washer, Item #: PS141913, Mfg: 090079352, 1900 PSI, 1.2 gpm power washer with the same pump/motor assembly. It oscillates on and off when the pressure builds up. I have cleaned the pressure valve and it did not fix the problem. I did notice that the white plunger slips easily through the o-ring in the bottom of the pressure valve which appears to be worn. I've tried matching up the o-ring with 4 different ones with no success. Dose anyone know what the size of the o-ring is? Thx
my royobi is leaking water out of the area you cleaned? i want to buy the whole new bottom piece you took out but dont know the name please help me ty. the brass [art you took out and cleaned.
