How to Fix a Pressure Washer (Part 2 of 2)

[@sandrakores8522]

Thank you ! Finally someone without a big ego just showed how to fix it without all the talk talk talk talk talk talk talk! Drives me crazy. I watched this and know what to do inside of an hour or less. Thank you Single mom trying to do her own repairs .limited budget and need to DIY these days! very happy to have finally found the right video!

[@Dakingz5150]

I honestly wished this man did every "DIY" video on KZbin.! I appreciate the thoroughness and knowledge that this gentleman shared. It was very informative and detailed. I thank you for that sir. But more importantly Im appreciative of his proper use of our english vocabulary. Because lords that some of these "KZbinrs" need it bad. Thank you once again.

[@FIXTechGuides]

Thank you for your kind words. Have a great day :)

[@kenzpenz]

Excellent indeed, I get the impression you have does this repair a few times. Another thing I noticed was how clean and organized your work space is. Sure hope this company is paying you what you are worth. Outstanding video in it's presentation and content.

[@Mike_S_Swift]

Mark, I started to pull my Sears washer apart and oil came out. I came in the house to find a KZbin video but my internet was down. I got my internet problem fixed today and watched both Pt1 & pt2. Thanks for posting your repair procedure. I'll have to look at the parts breakdown to see where my unloader is. I did buy an o-ring kit as water was leaking out the housing but I've had intermittant pressure problems with my unit until it just about quit like your video, thanks again/Mike

[@westhurman2819]

This was great info. I bought a Karcher at a yard sale for $20. When I powered it up, I discovered that the pressure was very low. So I put it in my shed and basically forgot about it. That was 7 or 8 years ago. Last week, I followed the instructions in this video and now have a perfectly working washer. All for 20 bucks!

[@FIXTechGuides]

Wes Thurman Great find! Glad we could help you save some money.

[@airizonneed520]

Great Video. I have been using my Karcher pressure washer for 4 years by having to disconnect the nozzle and then putting it back on to build pressure. I had no idea this was / is an issue. I have already ordered the new part along with a couple of O-rings for the wand assembly and a new water filter.Ya gotta love You Tube.Cheers

[@denniswhite664]

Whoops. Me again.. browsed and browsed the comments - and found reference to 15w-30. THANKYOU...I have a pump to tackle beginning this week. THANKS for making this video and making it available to everyone !!!!!!!!!!!! Just great.... appreciated more than I can say. TY

[@carlad5499]

Thanks for this video- My Dad is 58 and I pushed Play for him and it really helped him out. Great Video! Very Helpful!

[@RydersBigTube]

That was quite possibly the best, most professional and concise repair video I have ever seen. Thank you very much!!!

[@paulbecker2271]

nuh uh

[@RydersBigTube]

what the?! i didnt know u saw stuff like this. thats it - from now on i only give snarky, dastardly reviews muahahaha (i am rubbing my hands together evilly btw)

[@bschneid6737]

Nice video, refreshing to see a thought out, well edited video instead of something posted that was unsuccessful and unprofessional.

[@that1asianiw]

Mine is the same make and model and the same problem shown on the video. I used the same fixing methods described and my pressure washer is back in action. Thanks eReplacement and most of all to Mark for creating the video.

[@travanwue22]

These two videos saved me a trip to a repairer! Thanks so much

[@fsfltsurg704]

I've tried to tackle problems with my Karcher washer without much success. This was an excellent information video. I only wish I had seen it earlier! Thanks.

[@tb0nestk]

Thank you Mark and eReplacement Parts for putting out these vids. I sure learn alot about water pumps.

[@thilakawathy]

Hi There, I have the same problem with my karcher pressure washer. I am so impressed with your plain and simple explanation on your video. Even if I take it to a repairman now I know what the problem is and what sort of repair they are talking of. I am thankful to you for giving an excellent step by step illustration of solving the problem with my washer. I am going to try it as I enjoy doing this sort of job. Keep on doing your good educational services. Well done. Dr.Pon Sivaji

[@incognito9510]

Nice job Mark ! Without a doubt this is the best pressure washer repair video that I have ever seen . eReplacement Parts is simply awesome 😎

[@FIXTechGuides]

Thank you so much for the kind words! Glad the video was able to help with your repair!

[@ramfiscampiz7915]

Explained very easily to understand. This will be very helpful to me in the future as I have a pressure washer that has a couple of years. Now I know what could be the problem in the future......Thank You So Much.

[@MrLarryvest]

Wish I had found these two videos last week. Just tore my pump down and cleaned it. Got it back together and it is working great. I think I could have done it in half the time if I had watched the videos first.

[@whitesites]

Great Video. My Pressure washer is doing the exact same thing. No Pressure. I will be sure to use your site for replacement parts if I need any. Thanks!

[@dannewlon5825]

Excellent, great detail. I have seen enough in this one video that I believe I could repair my own pressure washer. I'm not expert but do have small engine repait skills. It's really nice knowing what I am going to be facing once I get in there.

[@drshindds]

You are great skilled and patient person. I feel comfortable tackling my pressure washer problem. Thank you.

[@verncutshall5950]

The demonstration was well done. It probably will save me a lot of money. There were two items I did catch you talk about. One is the gaskets that go between the major component as they go back together. The second is; what type of oil to use? Does the pump require a specific oil like the air compressors?

[@adriansnyder2036]

You guys really do a professional job of a top to bottom overhaul of all the equipment you show in your videos...You're the gold standard for small engine repair videos.

[@Blitz0203]

This is an incredible video ... Every detail clearly outlined, with advice along the way including proper lubricants to use with clarification of why the portions of the disassembly and reassembly is being performed. I have this power washer and already had replaced the loader valve, but did so without the pump removal. I found getting the valve out easiest by simply giving the pump a crank after removing the housing holding it in place. It pops out after pulling the cord once our twice. My problem right now is that the detergent suction doesn't work. I'm going tio carefully take it apart, and inspect the o-ring, spring, gaskets and check valve. I think possibly only lubrication and cleaning is needed ... But if that doesn't do it, I'll order the kit. Awesome video! Thank you for your time and expertise! Rick

[@MarkSimkoofLI]

An excellent video that clearly explains and shows how to perform maintenance on a pressure washer pump. The mystery is gone!

[@danielkidwell8712]

Thank you for posting this video, I had a problem with my pressure washer pump, I cleaned all of my valves, but did not know that the "re-loader valve" was a part that commonly fails, so I will inspect and replace that, if needed, ASAP. Also, thanks for mentioning what parts of the re-loader valve to and not to grease!

[@terryreiter787]

Excellent lesson on Power Washer function, dis assembly and re assembly.

[@AllenMassey]

Excellent video! Thanks for taking the time to show us how to fix our pressure washer.

[@Ali8888]

It makes me understand more about pressure washer pump. Really appreciate!

[@johnodell2074]

Your a good teacher, very well explained and easy to understand.

[@hansseebo8433]

Appreciate all this info...Just took my pump all apart and had to find out how much oil I should add into the housing before reassembly. Great inof indeed...Thanks again

[@marleneduhay3734]

Very helpful demonstration of the overhaul procedure of the pump. I have same pressure washer with exact problem. Thank you for sharing your expert knowledge as you show in your video.

[@rayovolt]

My dad found this helpful. And so do I. Thanks!

[@MrMcbunner]

All your video's are very informative. I've bought parts from you in the past and all have worked out quite well. I'll keep watching your info video's, thanks for you help.

[@riverrunful]

Very good and informative viedo. Thanks for taking the time to help us that don't have the experiance to do so. Bob, Orlando Fl.

[@BostonBeanah]

what weight oil did you use as a replacement

[@rodneydozier4124]

Excellent instructional video. I have a Coleman Powermate 2650 with an AR North America RMV25G30D pump. I noticed recently after I had used it to pressure wash a friends house that after three hours the pump lost pressure near the end of the job. The motor runs fine, but when the trigger on the wand is pressed there is no pressure, just average flowing water. I checked all the valves and O-rings that are easy to get to without opening up the pump exposing the pistons. I didn't notice any wear or damage on any of those parts. I then took the unloader off (part #AR42118) and disassembled it. I didn't notice any damage but did clean it and used some vasoline to lubricate the O-rings since I had read that on another site. I reassembled everything and then tested it. At the start of the pressure washer it continued to have no pressure and so I continued to press the trigger on and off and after about 30 seconds it started working correctly again. It did this a few times and then it went right back to having no pressure. Any expert advice?? I noticed you used plumbers grease, would that make a big difference? Also I did not remove the separate small o-ring and bearing at the bottom of the unloader since it was hard to remove down inside the pump. Would it make any difference to take that part out too? Any assistance would be so greatly appreciated. I just didn't want to waste $40 on a new unloader if I could salvage this one. Thanks again.

[@FIXTechGuides]

+Rodney Dozier If, as you say, there is no corrosion in the cylinders or other parts of the pump, My next suspicion would be the unloader. Even though is looks clean, that would be where I would go next. As far as the vasoline versus a different lubricant for the O-rings, they should all work in a similar fashion. You just need lubrication to help protect the seals and O-rings.

[@nickp76]

+eReplacementParts.com I have a simpson mv3024 Everything works great just for some reason it jumped threads and the pump discharge cross threaded/ stripped. I've only found while pump replacements, but it's half the price of a new one. any suggestions on how to repair or replace

[@winstonfosdick9887]

Thanks, very informative ! One small detail I might add is that I like to wipe a thin film of never seize on the crank prior to re-installing the pump...Next person to take it apart will thank you !

[@oceanspruce]

Great video. Now let me try it myself. I'll order the unloader valve from you. Thanks.

[@josephbrown5717]

My Karcher is the same model, and has the same symptoms as this one did before repair so I assume that I have the same problem and act accordingly. Thanks for the great video I'm sure it will be a big help>

[@FIXTechGuides]

Good luck with your repair Joseph

[@oceanspruce]

Your video instructions worked! My pressure washer (the same exact model as in your video with the same exact problem) is fixed (the same exact solution). I did get confused in a few instances where the video did not clearly show some of the smallest parts, but I was able to figure them out with the help of some parts diagrams. Thanks so much for your invaluable, professional help.

[@dabrennanyputube]

Great set of videos on washer repair/mtc.

[@edthecarpenter]

Water pump is working fine now. Thanks for the video

[@meo1960]

Excellent repair video. It really helps when people explain "why" they are doing something. Thanks!

[@melonyfaith06]

Nicely put into simple terms. Gave me the courage to service my pump without hesitation. What's the go on a pump that fluctuates pressure whilst in operation. Thanks

[@bsemanchik]

Pump OIl Change: I could not find anything on pump oil change on net. Your video solved the mystery!

[@sutonchef]

GREAT PRESENTATION AND TEACHING. VERY UNDERSTANDABLE. THANKS FOR SHARING THIS INFO.

[@LordoftheCats]

Excellent video. I had no clue how these worked but now I think I could repair one. Thanks. I know lots of times these just get thrown out or left to sit because folks have no idea that they can be repaired relatively easy.

[@foreverwood1963]

Good video, very comprehensive. I wish you all would do one explaining the job of each rubber seal.

[@FIXTechGuides]

Great suggestion! We publish new videos every weekday, so we will certainly keep that in mind! In the meantime you can subscribe to our channel so you won't miss it if we release that video!

[@gravelsandwich]

Great video mate. My Karcher has lost pressure and this tutorial is exactly what I was looking for..........................

[@FIXTechGuides]

Great to hear!

[@dansf100]

Mark, you're awesome. Thought my parents pressure washer was shot, but after watching your video, I'm almost certain I can fix it for them. Thanks a bunch.

[@franksandoval3850]

Great Video! Extremely useful in troubleshooting a PW pump.

[@glennlink7]

Clear and helpful. I wish I could bring my pump to his shop for service!

[@FIXTechGuides]

@PGXI The unloader occasionally becomes a bit corroded and can be a real chore to remove. The only real advice I have is to use a pair of needle nose pliers that have a very aggressive tooth on them. A few months back I purchased a pair of Snap-On pliers that have their Talon jaws on them. Basically it is a cross-hatch tooth pattern. They seem to really grip the tab on the unloader valves well. I hope this helps! -Mark

[@elizsawa73]

Thanks for helping me prepare for a job interview!

[@wesLEYcolvin]

Great job! Thank you. This instructional video, for me, is perfect. Exactly what I was looking for and needed!

[@19Dennis53]

I don't have that model BUT the video was VERY informative and interesting. The procedure was very well explained.

[@mexxbone]

Fixed mine in two hours after viewing....Thanks

[@lindenboy]

Great vid! Love seeing the inside of things...occasionally BEFORE I take them apart, often after I've already screwed something up!

[@CptnKremmen]

Thanks for a comprehensive instruction video. My pump is very similar so this will be a great help.

[@revjerrys]

Wow, still not sure I can do it, but without what you did I would be completely lost. Nice job.

[@johndangelo8873]

Thanks for the great video. It gave me the know how and confidence to replace the unloader valve. It was easy and my power washer works like new! Thanks again!

[@LoudSqueeken]

Outstanding video tutorial. Exactly what I needed to fix my problem. I have two comments that may help out other viewers. I could not for the life of me get the unloader valve out of the housing with needle nose pliers or even needle nose vise grips. It just would NOT pull out. There is a much easier way to get it out. HOW TO REMOVE A STUBBORN UNLOADER VALVE: Before removing the pump from the engine, unscrew and remove the white plastic housing from above the unloader valve. Lay a towel over the opening of the unloader valve. With the garden hose hooked up to the pressure washer, turn on the water. Start the engine. The water pressure will blow the unloader valve out of the its housing. The towel is there to stop the unloader valve from flying up and slamming into the cart frame. It works like a champ and will save you hours of cursing your needle nose pliers like I did. WHAT TYPE OF OIL TO USE IN THE PUMP The video does not mention what type of oil to use. My pressure washer is the same model as the one in the video: Karcher K2400HH. It uses Karcher 15W40 (Part # 6.288-050.0) but you can use any Non-Detergent Non-foaming 15w40 Pump Oil. I hope this helps others. Again, outstanding job on the video.

[@erniecook365]

outstanding I have replace the spill valve and cleaned the pump still have the same problem before I started. my pump was doing the same thing as yours in the start.

[@danholland2707]

Helpful video. Easy to follow. Good camera angles. Thank you.

[@robertcole5561]

Great video. You are very professional.

[@nrcuster]

@773cat No. I have a Craftsman 580 pressure washer too. Just pull the handle on the wand to relieve the back pressure and that should allow you to pull the start cord until you get it started. I had to replace the carb on mine last year and found this out during my problems with it. Now I have a low pressure problem like the technician demonstrated in this video, so I'm off to tear down my pump! Good luck!

[@cantdriveslo]

Thanks alot! Repaired my pressure washer with the info from this video

[@treyisog]

Great tutorial. One question though, what type of oil did you use to refill the pump housing?

[@DarkKnight788]

Well done. I am having a different issue however, found both tutorials extremely helpful as my Karcher G 2600VH has the exact same pump on it. Wish I knew about the oil before I loosened the four (4) bolts. My pump mounts vertically vice horizontally as shown in the video. Will know for next time when I go to disassemble the pump. Keep up the great work.

[@petercornelius8926]

MAGIC! Just what I needed to know - very careful, thought-through and instructive vid on the whole pump rebuild process. Thanks too for the clear talking and language. Pete in Guyana S America.

[@FIXTechGuides]

Glad we could help Peter!

[@FIXTechGuides]

@dougostey The primary part that was replaced was the Unloader valve. It is what was causing the no pressure condition. Occasionally you will need to replace some of the other o-rings. The valves can become pitted and need replacing but that is very rare. As a general rule when rebuilding a pump with a no pressure condition like the one shown you will need a new unloader valve, some Teflon and silicon grease and some 30wt non-detergent oil for the pump. Thanks for watching! -Mark

[@michaeljin101]

very great instruction and demo videos. I run into a similar problem with a different brand PowerBoss190 3000 psi & 2.5 gpm, I am having difficulty to open the pump housing. Hopefully get the right tool and will fix the problem following this video. Many thanks to Mark!

[@paulneat3449]

Very helpful! Exactly what I needed to fix my pressure washer - the same model you worked on in the video. Many thanks Paul

[@wranglersdad1953]

Very well done. I hope to check back for future videos.

[@pepperrko]

Nice job on a great video. It will be a breeze to repair my pump now. Thanks Mike! MO

[@GeraldThomasphotojunkie]

Great tutorial! Question: How often should I if ever, I take apart my pressure washer pump for cleaning and maintenance?

[@Countcrash99]

HI Mark, thank you for the video, I think the unloader valve is my problem. My wand & or the water outlet to the wand throws water all the time & the pump can't build up pressure. Its Sunday so I am going to take the pump apart like u showed me. thanks again I think I found my trouble..... thanks to all Richard McFall,,,,, Elkhart,In.

[@j.r.chasson3345]

Thank you for the excellent break down of the pump. Is just happens to be my exact problem. With the pump fixed, my honeydew list just got bigger!

[@Vicius440426rt]

Very nice, detailed instructions. Mega thx

[@richthornberg7786]

Excellent video. I think my pump has the exact problem. Thanks for showing me how to fix it.

[@denniswhite664]

Big thanks.. step by step - clear, informative, great great instructional/visual. But have to wonder what type and.or weight of oil is used?

[@reddirtndiesel1]

great video , Generally when my pressure washer is not working I just bin it !,, did not know you could buy seal and valve kit for them ,great to know thanks!

[@atomic432]

Thanks. Very helpful and good video technique also. Will watch it several times before I take mine apart.

[@ralvis22]

Thanks for doing this video. I followed each step along the way. Why teflon grease? Where do you buy? And how important is it to not use other standard greases?

[@kellyphillips7040]

working on a Karchr HDS 801 B. Company owned, so its abused not maintained. Anyways, recently brought it back to life by cleaning the pump and replacing a pressure switch. Ran about 400 gallons through it when the water flow stopped. Had steam coming out the wand. Went back to thewasher and before I coulddiagnose anything, the safety valve popped off so I shut it down. I did notice the safety valve was extremely hot. Checked for any clogs in the water system and seemed clear. Removed safety valve, disassembled and appeared to be some melted plastic around a plunger shaft in the main valve body. That's where I'm at at this point.

[@71371000]

An Excellent training Video, well done and Thorough

[@twowheellooney1138]

excellent tutorial that help us understand all the internal work of a pressure pump, would you comment on the other two possibilities for loss or intermittent pressure!

[@mcdusty62]

love your videos,you always make it look so easy it tends to inspire people and give us encouragement and makes us less nervouse to try some of the repairs we generally would dare to attempt,thank you so much.

[@IamRedeu]

In found one of these pressure washers partially disassembled on the side of the road. All the parts were there though. I watched your video, and set about to clean, and reassemble the pump so I could see what the problem was. As I was reassembling it, I was looking at the way the parts fit together, and it just didn't look right go me. The way the spacers sit in the piston guide shaft allows them to push in, and potentially bind. So I set out to find some assembly diagrams for the washer. I found exploded diagrams for the pump on your ereplacement parts website. According to the diagrams, the piston seals seat in the deep side below the spacers. In my mind, that would explain why there is so much space below the plastic spacer. I plan to take it back apart to straighten out the piston seals according to the diagram. Below is a link to the diagrams, and replacement parts. www.ereplacementparts.com/karcher-2650-11945130-pressure-washer-parts-c-33388_33389_34000.html

[@IamRedeu]

Don't forget to check your tip before tearing your pump apart too. For the one I found, the lack of spray was a rust clogged tip. The back pressure was tripping the unloader. It was as simple as putting it back together, and changing the tip.

[@IamRedeu]

Okay. The first time I assembled it per your video placing the seals in the same location as you do in the video. This is incorrect placement. The pump did indeed pressurize the water, but the missing seals allowed all of the oil to leak out onto the concrete slab it was sitting on. I now have a stain to scrub out of the concrete, and wasted several dollars worth of fresh oil. When you have the pump apart, the seals need to go on the piston half of the pump inside the deep holes beneath the spacers. Otherwise, you'll leak out your oil, and be running the pistons dry. Please correct your video to show the parts being placed in the correct location. I watched the video several times now, and you are absolutely putting them in the wrong spot in the video.
