Karcher K4 upgrades. 3 upgrades your K4 needs! back foot, hose and lance.

[@csnelling4]

Hay there Jimmy ,I must if had more porridge than you when I fitted my jet washer foot I just pushed the new foot/connector on !!! The hose and foot mod’s are spot on ,it stopped the hose connection blowing out under pressure .

[@josephxd6574]

This helped me out greatly and made the repair incredibly straightforward. Cheers.

[@brendakelsey5163]

Brilliant video. I had a leak just as described and ordered the spare part from your link. It was impossible to fit the metal elbow into the plastic bit, solution, soaked the plastic back rest in boiling water for 3 minutes, then easy peasy, now no leak. Many thanks.

[@lfautocosmetics]

I'm glad you found use from the video, Brenda. I wish I had thought of that as it is a very tight fit lol.

@@lfautocosmetics as of 2024 would you buy karcher with mods

[@matthewbaxter7502]

Great helpful video thanks for taking the time to post. That's what I like about these karchers all parts are replaceable. You're got a new subscriber. 👍

[@jd100-x1z]

Thanks for the video! Would you please have any tip how to efficiently reel the pressure washer hose onto the foot? I am always struggling with it (I have a new hose, not the original horrible one)

[@lfautocosmetics]

Unfortunately, I don't have a resolution to this. Admittedly, it is very annoying even with an after market hose. I just looped it up as best as I could and hung it over the top of the machine.

[@guttormh]

This is perfect! My Kärcher started leaking in this exact spot yesterday! Ordering parts soon!

[@lfautocosmetics]

It is a common fault, unfortunately. I'm glad the video has been of use to you. If you need any advice or help fitting the new backfoot, please get in touch. Cheers, Liam.

[@Java148]

Used Ali Express a couple of times and saved a good few quid. Thanks for video as I've just replaced back foot and going to get the lance next.

[@lfautocosmetics]

Yeah it's decent if you don't mind the delivery times. No problem, I'm glad it was of use to you 👍

[@Simon-fr4ts]

I have a K5 compact. Are there any upgrades I can do? I have replaced the hose, have a stubby gun and metal lance with curve on the end that fits onto the stubby gun, all quick release. I only use the Karcher gun and lances for cleaning the patio. I use stubby gun, MMC foam cannon (stubby gun fitting) and metal lance attachement for cleaning the car.

[@geedub2019]

3 years later, how did the hose last mate?

[@lfautocosmetics]

It's still going well. It lasted longer than my original K4 did anyway 😂😂 its on my new K4 and although starting to show signs of age, it's still working as it should.

[@steverabbits]

Great upgrades! I tried to order the exact same hose yesterday but out of stock - probably your fault 😂😂😂 I'll definitely be doing the hose. Mine already has the aluminium elbow pipe but I do wonder if the leaks happen because connecting and disconnecting the hose over time stresses the plastic ones and whether just leaving it attached would maybe make it last a lot longer or maybe even stop the leak from ever happening?

[@lfautocosmetics]

Hi Steve, thanks for taking the time to check out the video. Sorry for the late reply, I only just came across the notification 🤦‍♂️I hope you got the hose eventually. If they were sold out because ot Mr, I never seen a penny in commission 😭😭🤣🤣

[@Billynicho]

Hi can u get a quick release adaptor for the back foot connector

[@lfautocosmetics]

Hi Billy, I'm not entirely sure. I haven't seen it before but there may be one out there somewhere.

[@Billynicho]

@@lfautocosmetics thanks for your time, great video

[@lfautocosmetics]

@@Billynicho no problem, anything else I can help with, just drop a message 👍 thank you.

[@dotnetdevni]

Just ordered the hose 20 meter one as my garage is quite long to wear the car is parked. Hope its goes ok why when we spend 200 on a machine like this do they put in substandard parts annoys me x

[@lfautocosmetics]

I agree with you 100%, David. For all it would cost to replace a hose and a backfoot, it's crazy they keep putting them out with poor parts.

[@cwekas01]

Links added where to get stuff from would be a nice touch..

[@lfautocosmetics]

Thanks Tomas. I will get links and add them into the description. Please check back later and hopefully I will have it done by then 👍

[@lfautocosmetics]

Tomas, I have added links to the upgrades in the video. Thank you again for your suggestion 👍

[@neiltully4579]

Useful video thanks, however when attaching the patio cleaner the yellow grommet stays inside the gun head, bloody annoying obviously a design fault…..😡

[@dotnetdevni]

Tell me any options metal ones to fix the leek where u connect the garden hose to i find mine keeps slipping off.

[@lfautocosmetics]

If you mean the male connector on the machine itself, I haven't had to do anything with mines. You could probably get a brass or aluminium one but if its leaking, I'd try removing it and maybe use some plumbers tape then put it back on, making sure it's in the right threads.

[@noormancrabb6428]

Hi there, as previously posted I did the upgrade with the rear foot and the rubber hose. I’ve found that I cannot release e nose rom the full control trigger now, so I have to dismantle the trigger assembly to do so. I don’t seem to find spares for the release mechanism ie.e spring clip or release button. Have you any suggestions other than new unit. Thanks in advance.

[@lfautocosmetics]

Do you mean you can't remove the hose end from the handle of the lance itself?

[@dotnetdevni]

The k4 hose comes with it is rubbish any suggestions and also for attaching the hose any way to stop it coming off

[@lfautocosmetics]

Hi David, I have left a link in the description for direct hoses. That is the hose I bought. The swap over is very simple, it's literally one clip holding it into place so you just pop it out, put the new hose in and replace the clip. Doesn't take long at all. Hope this helps mate 👍

[@bradley1125]

Do I need to replace the back foot with the one in video if I’d like to replace the hose to the better one? Or can I just replace the hose. Just got this pressure washer brand new. Many thanks in advanced.

[@lfautocosmetics]

You don't need to replace the backfoot, Bradley, if it's just the hose you want to upgrade. The stock backfoot is plastic and is known to split so I just replaced it with the aluminium one. Hope this help. Cheers, Liam.

[@bradley1125]

@@lfautocosmetics Hi Liam, thanks again. I’ve been debating whether to stick with the K4 control or get the k4 compact instead. Mainly because the k4 compact appears to be easier to disconnect the hose. Would you say it is easy enough to change the hose. I assume I need to take the pin out? And is it quick connect on the k4 control Itself? Kind Regards

[@lfautocosmetics]

@@bradley1125 it is very easy to change the hose. There is one pin to disconnect that holds the hose onto the unit itself and then you just put the new hose in and put the clip back in to hold it in place. It's the quick release connector so literally takes 10 seconds to change.

[@bradley1125]

@@lfautocosmetics Thanks for the advice. I’ll be ordering a new hose for sure. I was reading that this metal back foot was karchers new approach at fixing the leaking problem. What is the chances the latest k4 model has this metal part now? I made sure to avoid the 2018.

[@lfautocosmetics]

@@bradley1125 no problem at all. If there's anything else I can help with, please don't hesitate to get in touch. I'm not sure but it would make sense to have the aluminium backfoot as stock for all they cost. Check out the link for the hose I use in the description. I'm not trying to punt sales as I get nothing from it lol

[@jason-si4mq]

Thanks got hose delivery today great thanks

[@lfautocosmetics]

That's great, Jason. I'm glad you found some use from this video. Hope all goes well 👍

[@dotnetdevni]

What u think of the hose Jason now that u have used it is the 15 meters enough?

[@Hobo-e4m]

When I connected the angled lance my k5 goes for about 5 mins then completely cuts out ....original lance supplied free it works fine

[@lfautocosmetics]

Is it the stock hose on your lance? The only thing I can think of is there me be a build uo of back pressure which is causing your machine to cut out. I'm assuming the K5 has a higher output than the K4 so that may be the issue. I've had no problems with the angled lance.

[@SilveryFoxster]

I upgraded the original K4 hose with Karchers own 10m hose, much better, no kinking and easy to wrap away.

[@lfautocosmetics]

I don't understand why they fit such a poor hose to the machines in the first place. Stick a decent hose on it and charge an extra £10-£15. Is the 10m karcher hose rubber?

[@SilveryFoxster]

@@lfautocosmetics It’s a smooth rubber construction, very easy to use.

My back food started pissing water, replacing with a metal one :)

It's a tight fit onto the outlet so will need some persuasion. Maybe better using a rubber mallet if you have one. Give me a shout if you need any help, good luck.

[@moonlighthowl]

[@moonlighthowl]

Also ordered a host, thanks for the tip, the one that comes with it is rubbist and way too short! :D

[@lfautocosmetics]

@@moonlighthowl I'm glad you found the video useful. The standard karcher hose is terrible 🙈 the hose I have put in the link is ideal for me. You can get it in 15m and 20m aswell if you need it longer

[@todmeister15]

Your upgrades are all ok as I’ve had the same problem with all three. However your lance set up isn’t fit for purposes as the way to go is just bin the lances completely and replace it with a short trigger lance that you can use with just one hand and so you can also use a foam cannon too

[@lfautocosmetics]

Hi Ian, thanks for your comment although I disagree with you. The setup you see is definitely fit for purpose. I also have a short trigger gun and where I find it useful for some tasks, I find it useless for others. For example cleaning the underside of vehicles is much easier with a lance, power washing the roofs of larger vehicles is much easier with a lance so you're not leaning over the paintwork. I find short triggers can put a fair bit of strain on the forearm if used for any length of time. Each to their own I suppose.
