So I've only used this pressure washer one time. kzfaq.infoUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP The one time I used it, it worked great. I recently had new siding installed but kept the old gutters and small areas surrounding my house that weren't replaced so they looked horrible and dirty because of the new siding. I needed to get it cleaned asap. When I used the pressure washer, man it just melted all the dirt and grime that was on those areas of my house. I used that krud kutter soap and it was over after that. Easy to assemble, feels durable, very simple to use. Also, I purchased a used one to save money and there was absolutely nothing wrong with it. I want to get more use out of it so I think I'll be washing the cars and update this comment as time goes on.

Cheers bud, I've just done this exact hack and its given the Karcher a new lease of life.

Good luck we need someone like you to help us repair instead of throwing away when sometimes goes wrong

Just grabbed me Karcher out of the bin because of this video!!! 😆🙌🏽

Thanks for this. I had exactly the same symptoms with the patio cleaner attachment. Even though water was getting through both jets, it was pulsing. After seeing this video I took the jets out and sure enough, one of them was sufficiently blocked to have caused the problem. All brand new now!

Very helpful, followed your advice and fixed mine too. It's also worth trying to unblock the jet first without dismantling as that may work for a minor blockage.

Thank you so much, I was just about to buy another nozzle, a 3rd one, you’ve saved me a fortune!! And all thanks to a simple pin, genius!!👍👍👍😢

That really helped me out a lot! When I opened it up, I didn´t see anything wrong - there was the hole in the nozzle and I could see thourgh it. But I cleaned it anyway and notized it became oval. It did the trick!

My brand new Karcher k5 smart control started doing this after 3 mins of use. Tried this and it worked a charm. Thanks!

Hi thanks for the video. which helped me sort out this exact problem with my Karcher. I have a Karcher with the three jet option spray nozzle that you have in your video, and like you, I couldn't remove the small yellow plastic section that has the last two screws underneath it (there are 8 screws in total for this spray nozzle cover). This yellow section is retained by two "clip"sections in the black plastic pipe, that have to first be squeezed inwards. These "clip' sections can be seen when viewing the black plastic pipe from the end. However forcing these hard plastic clips inwards whilst also trying to pull the yellow plastic section over the top of it, was at first impossible. How I solved this was to drill a very small hole (about1.5mm) through the top (end) of each clip section , again looking end on, and then installing a very small screw into each hole. These two very small screws allowed me to use a set of long nosed pliers to squeeze the clip sections inwards, with the yellow pastic cover then easily pulled free of the clip section. The reason I needed to open up the spray nozzle cover up completely was because the small metal tab that notches the movement between the three spray nozzle options, had dislodged whist removing the first 6 accessible screws. I have now super glued the small metal tab in place. I hope explanation makes sense for others trying to remove this yellow plastic section from this particular model spray nozzle

74yo F trying to fix Karcher pressure washer. Took the yellow thing 😁 off to see where water was spewing from inside. Found 4 small holes where 89yo hubby left water to freeze😱😡. Thought I could buy that part but what is it? Booklet? Oh heck no!😵‍💫 Liked your easy, explainable tutorial. Thanks

Brilliant…just what I needed. Great video - very grateful. 👍👍👍

Dude you just fixed my pressure washer. Thanks so much.👍👍👍👍

You’ve also got a leak somewhere as machine is pulsing. It’s a home and garden machine not designed for commercial usage

Great ! easy fix indeed thanks to your video. My k5 is back to life. 👍

The small metal piece is from the middle of the power gun (right next to last 2 screws - yellow plastic) and stays horizontal and perpendicular through the power gun

The metal clip goes back on one side of the outer case about half day down. the inner nozzel that doesnt come out has a grove going in, the metal clip groove going out so it clips into each other. You really have to pull the outer case apart as much as you can to see it not easy. I tried the cleaning but didnt fix the spinning cleaner and the second one only the flat spray one works.

Will give it a shot tomorrow. Cheers from Austria

Very useful. I will have a go. Particularly helpful as I have exactly that 3 in one model. I hav a second issue too that the electronic display isn't working either but I can live without that.

Brilliant….. worked a treat, thanks!

New Subscriber 😊 This was definitely worth a try as I have the exact problem you describe/show (lance with the 3 settings). Sadly, it didn't work 😩... in your experience, would I be right in thinking that the lance is normally the problem (as opposed to the handgun, which suddenly - mid wash (same time as I experienced the weird pulsing/lack of pressure) - decided not to recognise the 'normal' pressure washing setting/allow me to increase or decrease the pressure and continually flips to that weird/useless helicopter setting when you're trying to increase the 'normal' pressure setting?) Thanks for any advice you can give - really appreciate your time and effort helping others! 🙏🏼

where did you put the metal part that was in the 3in 1 tool?

Great tip, will definitely be taking apart the K5 Premium lanse later this afternoon and see if I can get the rotating nozzle going again, as it stopped working yesterday after hours and hours of cleaning. Am genuinely surprised that dirt finds it's way in the nozzle since it's a quite closed system that only receives water.

I’ve got the same washer, but it won’t turn off even when switched off so I’m sure the switch in the electric box is sticking. But also getting water trickling out from either the control head or the bottom of the pressure piston stem. Hard to tell where exactly it comes out from. Thinking I’ll just change the control head completely.

Dude, you're a lifesaver. Thanks

Where should i put the metal piece that fell out of the 3 in 1 nozzle?

Thank you for sharing the knowledge.

Great stuff. I have the same unit but the soap dispenser doesn't work anymore. Help please 🥺

I have a K7 issue with the nozzle making the same noise as yours, I opened it and cleaned it up. There's a flat metal not really flat, on the first nozzle that you opened(the one that you could not open very well) and I don't know where it came from. Please do a quick on how to put it back as I have searched on the internet with no luck, looking forward to your reply.

Any luck where the metal clip belongs, mine fell out as well and I don't know where it belongs?

My k2 doesn’t have the screws to undo like yours, how do I clean mine ?

💪 amazing easy fix, thank you

Thanks for this. Just about to follow your vid in the hope I can fix mine. Wish me luck 🤞

I think you’re awesomely smart.

Very informative

My k4 is doing this lucky for me i have my K2 as back up on a job. I've not done this to the lances yet but I did try the lances on the K2 & they worked fine. I'm wondering if it's the hose on the k4 that could be blocked up so I'm gonna wait until the new hose arrives & hopefully this could sort my issue out.

Where does the small metal bracket (visible around 4:40) go when it’s time to re-assemble?

My K5 smart is stuck on mix mode on the display. Any fix for that?

Great video

Hi, my Katcher K4 Full Control is making the same (grrr) noise when its on and not being used. Is this normal ?

Any ideea where goes the tiny bit of metal?

You… mate… are a legend!! 😅

Good video! My washer has no power! It was working fine last time I used it, plugged it in and nothing! Any ideas?

That's an easy fix, but in the background I can hear your karcher starting and stopping without pressing the button.....what is the reason? Thanks!

Mine is doing that but is not from that🤦🏻‍♂️ any other ideas?😬

Great video keep them coming

Please help me address the issue of my soap dispenser. I attached the bottle of soap to the spraybar but when I press rhe trigger, the whole thing doesn’t work. How can I overcome this?

Love KOI fish

It would have been useful to mention that the screws are Torx screws and to also mention their size. Otherwise very useful 👍 Your camera work and presentation will become more slick as you move forward. Have a looking at Cutting Edge Engineering which is a one man band, like you, who’s wife does most of the camera work and editing. Lots of useful techniques to provide guidance. Keep up the good work and keep safe.

Any ideas on why a k4 power control isn't reaching top pressure, gets to medium, but no higher. TIA

Hi I have a karcher K7 full control jet wash & I have dissembled the hand gun (the part with the display on) and I can’t get it back together 🤦🏼‍♀️ as I’m trying to find an airlock as the water is still spluttering from the hose after bleeding for 30 minutes. I have cleaned the other nozzle as in this video , so decided to see if there was a filter in the hand gun with the trigger 😢 TIA

My k5 has the pulsing problem but its the the actual machine part not the gun, when the gun is being used all works fine when you stop using the gun it starts to pulse like yours is doing any idea what it could be

Thank you..

Mine is pulsating without any nozzle on but doesn’t it I completely unscrew the hose

Hi my spray gun Karcher K5 UM hose doesn't click in? it just comes out? I have bought a compatible spray gun and the same things happens. Any idea?

Problem solved ☺️ thank you my friend. New subscriber

Grazie proverò il tuo consiglio!!!!!

thank you

Thanks for the video. It helped me unblock my 3 in 1. Is the 5 in 1 as good as the 3 in 1, same pressure? Might go for an upgrade

Mine does... Minus the hip gyrations though 😂

Great thanks

Hello sir, great tips. One problem I am having is my Karcher K7 turning on, working for 30secs/1min, then it stops. Then it goes on again. Any known reason for this? Could it be air or dirt?

there is a small metal plate you do not show how to install it back to the multijet. If possible, give some clue on how to install this small metal plate back with great thanks!

Hi mate, any idea what could be wrong if the pressure is quite low? Turns on normally but the pressure wouldn't be enough to wash a patio (barely enough to wash a car) It just happened one day and haven't been able to fix it since! Any help/advice is greatyl appreciated :)

For mine.. it's just the machine that does the pulsing. Not the nozzle. (When I turn it on it immediately starts pulsing. Without pressure/water though. It's just little energy bursts.) Anyone know anything about that? 😬

that little metal clip thing with an arch that appears at 4:09, where did that come from? I can't seem to find where to put it back, thanks!

Do yourself a favour mate, ditch the karcher and get the Ava washer. good luck. A

How about too much vibration.poor pressure?
