Other than getting the hose connector turned around (watch out for that one), the machine is simple to put together and use ruclips.net/user/postUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP . And very nice, too. I'm surprised at the power-it's more than we'll ever need, and we've not even used the most powerful setting yet.I've cleaned off a dirty concrete porch to get it ready for sealing, started to clean siding, and I know this pressure washer will be terrific for cleaning tools this fall.The only issue we had is we had turned around the hose connector, and it leaked. Once it was on correctly, though, we had no problems with the connection. Just remember that the end with the green knob goes towards the hose. It's obvious now what we did wrong, but not necessarily obvious at the time.
My Winner 11 had stopped working. It worked before I put it away last time, but it was dead on the next try. I found this film clip and used your tip to hold down the trigger and switch the machine on and what do you know, it works. Sensational!! Cheers! Maddo
great set of fix it vids mate. Ranks in the top 5 of fix it vids I've watched on you tube.This is how fix it vids should be done. Now to tear apart my Karcher. Thanx!!!
Thank you!
Mine had stopped working. It worked before I put it away last time, but it was dead at the next try. I checked the fuse which was OK and then searched on line. I found this film clip and used your tip to hold down the trigger and switch the machine on and Bingo! It works. Cheers! Keith
Have any advice in rebuilding a karcher hds 1000 b??
Good video thank you, I have a k5 140m it has low pressure and the on off switch is not working as the motor is in all the time , any help please.
I dismanteled my Carcher completely, changed oil, greased all bearings, reasembled it completely, than I realised I did not clean this little water filter at the housing...Cleaned it, works nice...Suppose, next time I ll do easy repairs first...
Hi Nick, I have a Karcher 6.450 washer. It won't sart up. It just hums. I have tried bleeding the water line and I have tried starting it with the lance trigger depressed. It still won't start. What should I do? Could it be a capacitor? If so, is that something I can replace? Thanks
PTFE tape may help on threads, great information of that common pulse issue. 🇬🇧
Pulsing can be due to blocked lance head. Dismantle head from lance, clean filter and replace. it worked for me.
Bought a Karcher last month, took ages to get started because my hands aren't strong enough to screw the water hose in - BUT, once that was all sorted it went totally beautifully and worked exactly as I had hoped. Today, I have spent more than an hour trying to get started and have TWO problems. 1] adding hose, as above. Have tried both the first and a different connector end in case one works better than the other. Neither works well and there is water everywhere. I am soaked through, but luckily it is very hot in New Zealand today. 2] When I have the water connected [more or less, water flowing in as well as everywhere else] I turn on the power. It either starts and runs for perhaps 1 second, or remains silent. It's an 80km drive up to the shop where I bought it - surely it must be something simple?
Nick I have a K3.96m that some one gave me. Trying fix it but it does not build pressure or stops running. Plus my soap jug fulls up with water. I would like not having to buy the whole housing assembly when it my be just seals. What is you thought on that?
Hi, I have a pressure wahser just like the one you have on the video. It runs well for a few minutes and then just shuts off. I cannot understand. Good pressure and everything it just stops working after a few minutes of operation. Would appreciate your thoughts. Thanks
Good in formative video, but would be better if you show steady close ups of damage instead of holding the part close to the camera and waving your hand about. However the info helped me repair my Karcher, so many thanks for that.
mine is leaking at the bottom of the outlet elbow where it goes over the o ring, i changed elbow & o ring but its still leaking?? any ideas
Thank you very much for the video, it helps me to fix my Karcher.
Where can I find the parts?
Hello I have Karcher K5.200, its humming but no pressure. I replace capacitor as it was burst and melted. But still the same issue. Can you let me know whats wrong. I have watched most of your videos so tonight, im going to check seals and filter area.
Hi, my pressure washer seems to have issue with pressure. It blasts water for 3 sec and 3 sec no pressure at all, so it's running between cycles of pressure and no pressure. What could be the issue you think. Thanks
the biggest tip you can get on pressure washers are do not by a alloy head unit
always buy a brass head units
Alloy and tap water do not mix
great video.
i have a karcher 320m
my issue is the last couple times i use it, the on/off switch isnt working properly. it is always on once you plug in the unit. when you turn it to off, it stays in the on position.
what is the issue?
would it be the brown internal switch gone?
thank you
Hi, I have this unit and not used it in a while. Tried this weekend gone and water is pouring from the trigger handle. Any idea what this would doing this or point me in the right direction please?
Thx Keith
My K2 seems to run the motor freely. It lost pressure and then the motor rpms increased like the motor wasn’t attached to anything. What could be the problem? Broken impeller?
Screws are Torx T-15 (not hex).
Hey nick.... Mate mine pulsates and is pissing out water..possible oring or loose bolt?
Hi. My karcher K3 is not working. I used it for long time mean more than 15 minutes. Now it is not working. According to you what may be the problem? Please reply
thank you for the video but I never again buying karcher . many problems and for any part I need 30 bucks the less!
your video is also pulsating, what is the fps of your camera?
Thank you for the video. question? My Karcher K392 is damaged by me. I made the mistake of putting bleach into the detergent reservoir. I didn't know better at the time. Now, water squirts out of the small tube that should be drawing detergent in. What parts do you think I need to replace and where can I purchase them? Thanks :)
Hello Nick. I replaced all plastic parts on pump and all seals/o-rings in all system and it still pulsates and have no pressure. can it be that some of parts was placed in wrong?
hello Villijs, it could be a number of thing, I recommend pulling it all down again, then seeing if the seal between the control head and cylinder head. also try to see if the water flow to the cylinder head is good. let me know how you go :)
Yeah I don that and I noticed that I forget to move one part from old to new what didn't came with. now it works flawless :)
good to know :)
Hi Nick, hope u can help!!! pressure washer, lost all power hubby replace fuse after fuse keeps blowing them. Could there b a lose wire some where???
Thanx dawn
My Karcher 395 has been a real workhorse over several year.. It has pulsed a few times off and on with nothing changing as far as pressure and working correctly. Just recently it made a noise and now it will not "idle" down off of full pressure when you release the trigger. It still runs full power with the trigger/water off. Electrical or internal parts? Ty
Hi Nick, l was just wondering l have a Karcher K4.97 and when l press the trigger l get a 5 second delay before the machine starts up. Is the fault the control pump head out something else.
Hello I have a karcher and when I turn the water on , water pours out from the handle and trigger area. what will I have to replace or repair in order for this to stop. It also is not building any pressure.lHELP!!!
Hi Nick,
I have watched your 3 videos on repairs, you seem to concentrate on leaking and pulsating. you did mention very briefly on no pressure.
My problem is that with everything hooked up, there are no water leaks and when the pump is turned on, and I press on the trigger it starts up and sounds like it is running like normal but does not pressurize.
The only water that comes out the end is from the town water supply.
The thing that has me stumped is that the unit turns on and off like normal using the trigger on the handle and does not get any high pressure ?????????
Do u found a solution?
Hi my washer does not pump detergent even when I put the washing wand on the "mix" setting or use the brush wand.
Please do you have any ideas what might be wrong?
I have a parkside 150 E4 it doesn’t come on at all it’s only year old
Where is part 2
Can yuo tell me please how much oil, and whaat type of oil to use inside the machine once the head is off please.
Motor oil 10W40 half full
Regarding the seal at 5:18, what about the little seal type o-ring that broke off of the connector, not the one that wraps around the plastic but the one that sits at the end of the brass component? What is that called? Every time I turn on my pressure washer, this part shoots off of the unit and I need to screw it back on...
Torx T15 not hex drive man. Completely different patterns.
Hi, Plz how to fix low pressure on k5.200

my pressure water pump keeps running but has low pressure. I have checked all the common problems listed in owners manual but none of them apply
Hi nick can you advice me what part I need to change in my k3.77 as I used it with warm water. The engine is running, but the pressure is very very low, like you can wash a toddler feet with it.
Thanks in advance
I'm having trouble with mine, it's pulsating but the seals look good... Also, it's constantly leaking from the detergent thingy, even when turned off.. any ideas? I could replace the whole cylinder/control head but as many stated, you might as well buy a new one :l
Sir! If this plastic parts is crack, is that any way to fix those parts?
Buying new parts is more than a new machine.
I have a cheap plastic welder but no luck. Need to spend much more on a good setup. Leaning curve might be a little steep and some plastics could not be repaired.
Have a k4 pulsates when I plug it in without turning the switch on
Wjat about 3d printing those parts? Anyone?
60 bucks for the two pieces at 2.38, and a new machine cost about 150, so i would sell
the old crapper for parts for 25 bucks, and buy a brandnew one, and don't have to
take it a part for at least 6 years or longer.
OUR KARCHER PULSATES WHEN TRYING TO USE THE T 50 CIRCULAR BRUSH HOW CAN WE FIX THIS
Help anyone! When I plugged my karcher k2 into the electric mains yesterday there was a crack and flash from inside the casing. It doesn't work anymore. Any advice appreciated.
i have a karcher HD 525s I cant even get the thing to power up ?
I had this problem with mine , my fix , got a Bosch cheaper and better built
Simple solution for me: no more Karcher
0:13 Is it a chainsaw or a washing machine?
Mine shuts off as soon as i turn on the water and doesn't start until i hit the reset button
hi Nick. thanks for your vids. I have an electric k4.99 unit. While replacing the pump head, some of the oil leaked out. Karcher sell a replacement 50 ml grease but also said I could just use 80W90 G-L5 or 15W30 non detergent. However, my local auto store does not have non detergent oils, they all have additives. Any recommendations, does it matter too much.
My Karcher small pressure washer will not start. It is plugged into a good outlet.
Better to buy a new one
Good video. Thanks
Hi Nick, I have one karcher with me and when I turn it on it keeps the motor on and it doesn't build any pressure. It was working fine but after a 10min work this morning it stopped working, no pressure is built and it doesn't turn off if I don't switch it off. If I doesn't turn the switch off I reckon the washer would run until it breaks because the motor is not stopping and there's no pressure being built. It doesn't matter if I push the trigger or not, the motor keep running non-stop just if I turn on the switch. Any idea what it could be? If I change the parts you suggested in your videos do you think the washer could work again?
No that is a different issue, there is a high pressure non return valve inside of the control head (not the valve body) which is allowing all the high pressure water to flow into the garden hose. replace that and your problem is solved
I have this same model. It has a leak , a pulse , and low pressure! Could that be the cylinder head ?
The cracked head is near the pressure relief port--- the point with most stress and the thinnest part of the head--- bad design😖
hence why im no longer buying karcher junk with plastic manifolds....
how did you fix it? !!!!!!!
Karchers are junk. Neighbor and me bought the electric models independently a few years ago. Both of ours developed leaks shortly. His went first putting out on the sidewalk for trash pickup. Mine went about a month later and and also gone to the dumps. I tried to fix it but was so surprised to find the pump was plastic and had a crack in it thus the major water leak. Plastic pump, high pressure stresses and manufactured at a low price point do not end good. If you could fix it then fix it but if parts cost close to a new one, don't think it's a good idea.
You forgot to add the most simple fix to check 1st. As just resolved this problem without doing anything on your video.
hi there my kracher doesn't start at all can you help me
hola que tal ojalá lo pusieran en español, se los agradecería mucho...
why do so many Karchers leek, and dont tell me everybody puts them where they freeze in winter, i think its because they use plastic parts where the most pressure is and they mostly tend to split, a very poor idea for the customer!
Best thing to do with a karcher washer is take it to the bin there plastic crap and the parts are expensive,made in china now says it all!
Minds ain't turning on at all ???
un a karcher 4040 off a 700watt petrol genarator
Cheap plastic that explains it.
these karchers are crap. i have had two of them and they both only lasted 2 years
Karcher is a piece of shit.better buy other brand.
