So I have a Karcher too and was having issues with depressing the handle sometimes didn't engage the pump. I knew it was the unloader valve and had located it but couldn't pull it off. Watching your video gave me the courage and confidence to just pull harder which I did and it came off. Cleaning resolved the issue. Thank you for posting it was very very helpful. Happy homeowner now :)
Hey Richard. Great video. I bought a used Karcher pressure washer yesterday and it worked great for the first 2 minutes, then I lost pressure. I found your video and fixed my pressure washer. Great Thanks for sharing.👍👍
Wow, that's great! You're most welcome. I'm glad and very happy to know that I could help you. Thank you so much for watching, commenting and the very kind words. I appreciate it greatly. All the best.👍😀
I believe you put the little plunger in backwards, correct? Doesn't the flat end go against the piston that you pulled out with the needle nose pliers?
You may be right but as you saw it worked great and continues to work great. Thank you so much for watching and commenting. I appreciate it greatly. All the best.👍😀
Richard - You put the THERMO VALVE in backwards which will ruin your pump! The valve that was the issue with your pressure washer and had the torn o-ring is known as the SPILL VALVE. The THERMO VALVE goes in the plastic housing above the SPILL VALVE. * At the 6:46 mark, you show the CORRECT position of the THERMO VALVE. * At the 9:35 mark, you reassembles it BACKWARDS! The long thin part of the THERMO VALVE is supposed to be inserted first into the plastic housing. **If you install the THERMO VALVE backwards, then the pump water will overheat and RUIN YOUR PUMP!! If the pressure washer runs for more than 5 minutes when the spray wand isn’t in use, the water in the pump often overheats, causing the THERMAL VALVE to open and discharge hot water onto the ground (that is why there is that black cap to divert the hot discharged water downward). When the THERMAL VALVE opens, cool water enters the pump and cools the system. Once the pump has cooled, the THERMAL VALVE closes and the pressure washer operates normally.
Good camera angle and instructions. I have a Karcher 2400hh where the pump is in the rear instead of beneath the motor but other than that it's the same. Thank you for such a helpful video.
My Karcher is electric and 20yrs old, it seems to be an intermittent problem similar to yours, will check it out when I get round to it. Another great video most helpful thanks.
At minute 9:36 you show the plunger pin facing down. My unit will not go together this way. The pin moves into the cap. Installed as shown the pin will fall down. No?
I noticed the samething. I'd advise putting it back the way it came out. He probably changed it back after trying to use washer and just didn't show it out of embarasment.

I ended up using needle-nose locking pliers to get valve out. I needed to grind nose of pliers in order to get it into hole where release valve is located
David Lemanski I am sure the O-rings were chewed up when you got it out. That's usually why they are so hard to take out. Did you get it fixed? Thanks.
I filed down my long nose locking pliers and I was finally able to get them to grip and remove the valve. I bought the pliers brand new so filing/grinding didn't even cross my mind. Thanks
Josh Christian Sounds like it is seized in there. They make a pair of locking vice grip needle nose pliers that might help. Here they are at Amazon: amzn.to/1IRZHxS

So that was 4 years you had that backwards. How is the pump working now?

You're welcome. This is a very common problem. Thanks again for watching.

thank you Richard, it saves me money, because i can fix my Karcher presure myself, thank you very much for the video.
You are most welcome. I love hearing that I was able to help you. Thanks for watching and the very kind words. All the best.
I noticed that when you took the valve out, the plunger was one way and when you re-assembled the plunger was backwards. Any reason behind?
I noticed the samething. I'd advise putting it back the way it came out. He probably changed it back after trying to use washer and just didn't show it out of embarasment.

Where can I buy the pressure valve cover?

Richard , it was very helpful , i have a electric 750mx but the result was the same , and it works again , thanks
You are most welcome. I am glad to know I could help you. Thank you for watching, commenting and the kind words. I appreciate it greatly. All the best.👍😀
thanks really help minds leeking right there so i need new orings right
It's very likely that they are damaged. Best to way to find out is to take it apart. Thanks.
Same parts as on the 2400 HH, Karcher has not fixed the issue. So many problems with that unloader valve.
Thank you for watching, commenting and the valuable feedback. I appreciate it greatly. All the best. 👍😀
I’ve change the thermal valve and unloader valve and after about 3-5 minutes of high pressure, the engine bogs and dies….HELP!
Perhaps you have the parts installed incorrectly. Thank you so much for commenting, watching and the very kind words. I appreciate it greatly. All the best.👍😀
I replaced my o rings but I'm still having the same problem the peace is not messed up in any way
Did u put the plunger backward?
I do not believe so as it worked perfectly fine as I tested it. Thank you so much for, commenting and the very kind words. I appreciate it greatly. All the best.👍😀
Thanks. Now I know what is problem with my Karcher M520.
You are most welcome. Thanks for watching and all the best.
Thanks!

David Lemanski Great! You are welcome.

You're welcome.
good job, thanks!
You are most welcome. Thanks for watching and commenting. All the best.
Great video, thanks!
Ok Now you need to ajustment on your Governor spring to stop the motor from upland down fast slow you can do it if you try
Sorry but I no longer have the machine to do that with. Thanks.
Thanks I just bought one with the same problem for 25$
Thanks.
My pleasure. 1900+ views and you were the first to bring the issue to my attention. Thanks to you for that.
I appreciate that too.
I am unable to get the valve out. It is stuck. Any ideas?
Josh Christian Try some spray lubricant. WD-40, silicone etc. Are you using needle nose pliers to pull it out?
Yes I'm using needle nose. I've tried wd-40 nd fabulous blaster. Let it soak over night in the blaster nd it still won't budge.
Josh Christian Sounds like it is seized in there. They make a pair of locking vice grip needle nose pliers that might help. Here they are at Amazon: amzn.to/1IRZHxS
Ok. Thanks
Josh Christian You're welcome.
