Karcher K2 Compact Leak Repair 

Other than getting the hose connector turned around (watch out for that one), the machine is simple to put together and use ru-vid.comUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP . 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.

Yes i had the same problem ! Thanks for video. It helped me understand what to expect when opening up ! btw, the part no. is 5.064-396

Good tip and well presented. Part was expensive for what it was but the easy repair took 10 mins.

What's the part number/name?

Sorry!but I wouldn't bother. Bought a K2 from amazon,and after 2 impressive washes the motor re FC used to start so no pump. Sent it back and received full reimbursement. Karcher had better sort the problem out fast or risk losing there reputation.

Just checked mine which was leaking and when testing, it leaks in the same place. Cannot physically see a hole or crack but £12 on Amazon is better than a new machine!

Thanks for showing this video. Fixed for 25 euro (including shipping). Otherwise I would probably have kicked out the device.

Sometimes u can heat a screwdriver and melt the plastic over the hole ..like we did with footballs as a kid

Today I just find same pressure washer on waste yard for free lol Have no ideas what is wrong just bring home trying and is work great but have exactly same problem so having now pressure washer for free just need buying new part for few quid. Big thank you for this video and sharing your experience.

thanks for the video, mine leaks exactly the same and wondered if it was an easy fix

Thanks we’ve just fixed ours fairly confident it was that part as was leaking from the same place, anyone else considering having a go and no confidence, i’m no diy’er and managed to fix it so worth a try for £15. Now keeping our 8 year old son entertained during lockdown lol.

What is the part called or part number please?

Russel from png port Moresby I tried epoxy glue never worked so after watching this quick fix will order mine.

Do you know what tyoe gearbox oil they use in this has I made the mistake of uncoupling the whole of the plastic unity from the motor and spilt oil out of it. It looked like some type of synthetic oil. Not sure of the type of oil or exact quantity

Great video, saved me buying a new pressure washer. Many thanks!

awesome, and no going on and on and on and on , short and sweet

Hi, silicone was never going to work with so much pressure being forced through the part. I would of tried epoxy resin in and around the cracked area I'd be almost certain it would hold, only a few quid from toolstation and dries seriously strong in minutes!

Thanks helped me out this video 👍🏻

Great video, thanks very much! - I had the same issue on my K2 I tried to super glue the seam with no joy so ordered the same part from amazon - worked great!

I just took mine apart. Tomorrow will do what you did and see exactly where it’s coming from.

Whats the name of the part !!! Where can i buy itt ?

Many thanks for doing this. Helped me out a treat 👍

Just the vid I needed to see. Excellent. Thanks!

I had the exact same issue (still in 2024). I ordered this part on amazon. It was bought more then a thousand times. Karcher failed on developing this part as it seems to leak at the same point. I hope they will build a more solid part or change the design because it's a very tight corner where the water is pressed into. If they will not upgrade it in the future I will switch brand.

Cómo quitó la salida tengo el mismo problema de ahí sale el agua y pierde presión, link de compra

I have same issue, and this short video helped me to sort it out. Thanks, all the best

Superb - this fix worked a treat !

Thanks so much for this - worked a treat!!

What kind of screwdriver have u used for taking the housing off coz i cant get to the ones in the slot?

Hi, I need the same part. Can you help with where you got it from? Part name and number please . Thanks

My one seems to be leaking at the part that has that clear rubber tube connected. That cylinder is leaking, and the pressure of the water is lower than it should be?? No cracks or anything, so I have no idea what's the problem is. Maybe a rubber grommet needs to be replaced? It's really confusing as it has been fine until a random leak.

This video helped me fixing my Karcher K2 compact. Thanks a lot TD...!

My leak is on the actual cylinder head or the thrust assembly, whatever it is. Espares sell the part for £87. Ewaste, more like: time to bin it because its cheaper to buy a new one. The motor assembly is full of watery grey oil and will all fall apet when opened. There are many components inside which can fall on the floor without care. Partmaster do exploded views of the motor assembly if it does all fall apart. As I said, my spray eminates from within a nook of the cylinder head; the black part visible further back from your leak location in your vid. I've spent an hour pulling this apart and it'll take another half hour to reassemble: unless your leak is in the same place as in the vid, I recommend trying epoxy and not disassembling it further as it's a waste of time. Would be good if you showed hoe you fitted your purchased part to the machine, not that it matters in my case though.

excellent video and step by step instructions THANK YOU I'd like your advice about a connection of an attachment to this outlet valve so I can use a quick connect hose instead of a screw connection

I had to open my karcher to fix but did not have a screw driver for the bootom screw to deep and narrow so i used a angle grinder to open when fixed i sticky taped it back together works well hope this helps

Karcher distributors want $75 bucks for a part for my $150 dollar pressure washer. Who knows how long the machine will last after the repair?

I had same problem and thank God I found you here to help me see where do I put the silicone and the little rubber bought new.

Tengo una igual pero no anda el automático. No enciende con el botón , al ponerla directa si funciona . Alguna solución...?

Homa haber si alguien me ayuda como se llama. El destornillador que usa por favor

that fingers crossed is what nailed it ! thx . i too have a basic model , but with 5 year guarantee, still, i hope i won't have to bother with this

Hi i have a karcher wch had a same leakage problem. I resolved with some good glue, now the outlet wall which is connectes to the gun pipe ( the from which water runs out from the machine ) keeps on removing. Any solution please?

I have same problem need one new Shop Address pls

Great tip - thank you!

I got the karcher k2 compact car kit, which misses that house. Seeing the internals, i guess i find such a hose i can convert it quite easy.

Mine leaks in three places. Utter rubbish

Where did you buy the new part from please and what is it called

Tengo de esas.mismas.pero no tiene fuga de agua me podria ayudar porque pierde presion mejor digo ya no tiene presion

hi..... what is the name of that spare part...? badly need it also..... pls.help me.....

I have the same issue. £15 to buy part from eBay, is that the cheapest place to buy from?

отлично!

so all you did was replace the O ring? nothing else?

Can I buy these parts separately

How does the outlet come off?

Mines failed at the joint with very little use

well guess what. now my k2 started leaking too haha ...

from where u got the part?

You didn't necessarily need to take the pressure washer apart you could have disconnected the high pressure hose form the machine and replaced the seal that was damaged

Whats the part number with rubber ring included
