Great instructional guys. No 10 minute chatter before hand like all the US guys like to listen to thoer own voices. Just simple straight forward clear advice. I have this machine and it's a rare thing now.
Appreciate the support! These were the golden era of machines built to last
Thanks for posting this. It gave me insight into how to fix my Archer 410. Blessings
What a great video - great instructions and diagnosis - saved me hundereds of $. Loved your explaination of the symptoms - thanks
Appreciate the comment, thank you!
Exact same issue a few months back now it wont reach full power even when adjusting the nozzle.
Excellent video. Thank you so much. I have 3x of these machines and each one has a similar problem or leaks. I never had the confidence to diagnose the problem but now I will give it a go.
Great! And thanks for the comment
When I had a boat my 620 was used very often but now it is just used once a year and needs this fix very often. But I always have to check the procedure here, so thanks for the great video. A couple of points. I manage to get the unloader out without removing the electric box by sliding out the rubber attaching the electric box to the piston housing. Also, if the piston is stuck fast, be careful not to damage/bend the thin piece of rod using pliers. If you unscrew the rod from the piston, you can put in a long bolt and give yourself more power/ leverage to remove the piston and replace the rod undamaged.
Thanks for the info.
Wont help me with Karcher issue but well made instructional video 👍
Thanks!
Excellent video
Thanks!
Great video 😊
Thanks for watching
Very good explanation😊
Thanks, appreciate it!
Thanks so much I did the same and it worked fine ☺️
Awesome!
Thank you so much for the class about cleaning solenoid valve
I have my Karcher 620 M since 1997 and I love the machine, but during this period I've probably sent the machine at least 15 times to clean this solenoide, thinking tha it had to be replaced.
I probably invest about 02 ot 03 time the machine's value, reparing it
I'll not send it anymore to the technical assistance.
Thanks for the info!
Thankyou for your helpful video. I had a problem today with my 620M which cut out and it was the machines thermal switch which reset after 30 mins. The reason was my own fault as I fitted a rotary lance and didn't bleed through first. It jolted the system and cut out. Okay now, though I do have this same issue you had too, so a rebuild is something I shall have to do also. It is over twenty years of age and worth looking after.
Thanks! Glad it was useful.
@@AutoBuddynz I followed your video and took it apart this morning and rebuilt with a clean and grease. It is now working properly. Thankyou again.
@@brandywell44 Appreciate the feedback, thank you!
Thank you
Appreciate the comment!
Thanks alot for the video, it really helps us diagnose our waterblast. Just one more thing, how to get those sets of rubber rings and those kind of grease?
We got that from our local Karcher Dealer just ask for the parts / service department
Is it possible to deliver to Fiji if I place the order from Fiji?
@@faletiute I suppose, might be best you contact them via email
Hi i have the 620m and it all starts but have no pressure at all anything you could help with please thankyou 👍
I have been offered one of these K620M machines. How old are they and are they a long lived machine worth rebuilding or better to purchase a later model such as the K5 series? Thanks for the clear video.
Pls show about hd 5/12 full service
Thankyou for your very good instructional video. For many years my old 620 has suffered this problem and now I know how to fix it. I have another problem with my 620 though the switch on top of the unit won’t remain on when I push it down the way I keep it on is by placing some very heavy sticky tape across it . Any idea how I can fix it.
Thanks! Open the switch and see what the issue is. Not difficult to replace this with another waterproof one if needed.
What sizes are the orings?
Et pour le détergents comment il fonctionne sur 620m
What type of grease is that? It's a great informative video. Thanks
Its the grease Karcher supplies. Just visit your local dealer. White type of grease
Hi, great video, I have a K5 not the power control one just the normal one and it doesn’t seem to have any power as in when you turn it on with everything connected nothing happens I’ve left the water to go through as some people say about the air locks but even after trying that and taking it apart I can’t seem to find what’s wrong with it?
Any help would be greatly appreciated thanks.
Hi thanks, does the electric motor start running? As it could be a bad motor start capacitor or maybe the on /off switch is playing up on top of the water blaster.
@@AutoBuddynz Hi thanks for getting back to me we took it apart and water had got into the coil.
Where did you get your o rings from as Karcher have discontinued
Kits are available on eBay.
@@AutoBuddynz thanks ... but I found them at ABC bearings
@@alessi1973 thanks for the info, I'm sure it will be useful for others. Do you have an address?
