Hi ... not sure if this is still being monitored, but I had a K2 Home pressure washer. It was 15 months old - well taken care of and used about 2 dozen times during this period. Stored in garage with water drained from the system and hoses. The last time I used it ... I washed 2 cars, and took a short break 5 - 10 mins before attempting to use it again. Whilst it was sitting idle it was powered on at the switch but with hose pipe turned down to about 50% of mains full pressure. When I returned a short while later and getting ready to use it again I turned the mains tap back up to full pressure. I then noticed intermittent humming and what appeared to be 'smoke' coming out of the unit. I took the lance and jetted some water through which seemed to be working okay, but the 'smoke' returned after I stopped the jet. At this point I decided to turn the unit off, and then wanted to unplug the cold water supply ASAP thinking water and electricity don't mix to well. When the hose was unplugged scolding hot water shot out of the cold water inlet - and what appeared to be more water than what would normally appear when unplugging the hose. I have had the unit checked - and the verdict is that there is no fault with the unit at all. In your view, what could have caused the water to get so hot even though the unit was sitting idle. Surely if the power switch is on and the trigger is unpressed then there is no electricity running through the motor windings and therefore no heat is being generated as a byproduct of electrical to mechanical energy. I have seen references to pump bypassing - is this something on this model - and in this mode what is taking place? If bypassing is taking place then I understand that a thermal protection device (valve) should be fitted at least for safety reasons. You thoughts are appreciated. Thanks. J
Hi Jay, nice info for us to work from. OK lets break this down, reducing the tap flow will only reduce the pipe pressure when operating the machine, when stopped the pressure will equalise to full main water pressure. Humming when not running and heat from water indicate the motor must have had some power as the pump does not produce measurable heat and will be cooled by the water. The smoke may be from the switch arcing or the motor so check both.
My Karcher pressure washer has 5 pointed star headed screws to make opening it difficult. And they are deeply recessed - but the drivers can be found on the net.
Hi Graham, they are TORX and you should be able to find them but we sell a set www.espares.co.uk/product/es1251179/9-piece-torx-head-screwdriver-set?pageNumber=1&SearchTerm=torx%20screwdriver
Hi, Very nice understandable video !!! I have a problem with my Karcher 3.55, It has given great service, but while using it yesterday, and after stopping it for awhile, it refused to start...just makes a buzzing noise, and when I was disconnecting the water hose, a jet of very hot water sprayed out of the machine from the input connection. it was really hot. Is the motor "cooked" ??? Any advice appreciated. Thanks Jim.
Hi jmreire1, we have never known them spray hot water unless they are connected to the hot tap, get inside to check the motor and pump to see if it has been damaged.
@@eSpares thank's for your reply, I was very surprised myself, as it's a cold water power washer,,,,it does not have heating capacity. So must be something radically wrong with the internals....I pressed the snap-on connector to release the hose, and WHOOSH, scalding hot water gushed out. Will strip it down and see what I can find. It has never been otherwise than a perfect power washer up to this. Thanks again, for your help. Best Regards, Jim.
Hi, found your video/s useful and although my Karcher is slightly different (K4 Premium Ecologic), managed to apply it to mine. My problem was that it seemed dead, not running at all when turned on (had it a couple of years, but not had much use from it). Stripped it down and did checks you suggest - but not sure about last motor bit. But have found that it runs with a quick turn on turn off of the switch with the little cylinder head and piston assembly removed (ball race / cam mechanism exposed, but all electrics sealed and safe). Starting to reassemble and partially tightened down doesn’t run again. Loosen off to about 3/4 way and it runs again! Any tips or ideas as to what’s going on? Cheers
So if resistance between both neutral and live across the switch, AND the resistance across the motor terminals are all 7.5, what does that mean? The only ones that are low resistance in my non-functioning motor are the live and neutral wires from the plug to the switch.
Hi. I have a Karcher K2.15 that was poorly stored and was exposed to wet conditions. Recently, I have tried to use it, however, each time I turn it on, I can see arking from the brush. Any suggestions on this matter?
Thanks for your video, but unfortunately it did not answer my question. I have a Karcher K3.150 and I have bypassed the switch because it was bad. My question is: does the switch have a mechanism to disconnect the power when you take the hand from the gun trigger ? Thanks.
Hi Wake up People, the switch is a micro switch that makes and breaks the contacts inside when the trigger is released, if it has gone faulty it should be replaced.
@@eSpares thanks a lot, I have open it again, found the problem and use some heat to reshape that plastic stick that is actiond by the button. Also added 50 ml of 5w30 car oil because the old one leaked while working on it. Thanks a lot for the help. I hate Karcher because how they build the switch for obsolescence so people return every few years to buy new units.
Hello. Recently bought a K2300PS and came with some oil stains on the box and also on the machine. I was wondering if this could be a lub leak from the machine or just an external incident during transportation. I have not use it yet because I'm not sure if it is secure.
Thank you for reply. The sparkling is coming from the motor carbon brush close contact to rotating commutator. What will be the problem even the brush has beeb replaced.
Hi, Any ideas why the K7.85 when switched on wont start before i go stiping it down? Use a wee sparky pen and it shows power all the way along the cable. Switch it on and nothing! any ideas please? Many thanks Ian
I have a VAX VPW4 pressure washer and have found a line fuse connected to the on/off switch has blown. Why is this there and where can I get a replacement? (its a 20mm, 13amp 250V ceramic fuse). VAX say this is not a serviceable item??? Any help would be appreciated.
Your video gave me the confidence to check the machine using a multi meter (bought one ,so useful as you showed).It would be helpful if the video expanded on how to check the switch and capacitor and motor(what the readings should be when healthy) using the multi meter. My K2 compact suddenly stopped, electrically dead ,no inital kick,no pressure,water flows through machine and lances .Any idea what it could be.I have checked and i think it may be capacitor .
Hi William, the easiest way is going through the circuit as shown in the video, you would expect a low resistance reading from the live to the motor, neutral to the motor. The switch you should get nothing across the terminal when off and a reading when on, the capacitor should be tested on a high ohms range and expect it to start at zero and move up but normally there is signs of damage.
Thank you for replying .The meter reading across motor +/- to switch +/- is 8 Ohms each.The capacitor terminal (brown +black) to terminal with two black(over capacitor) gives 7-8 Ohms.I have a multi meter which shows open circuit when checking capacitance .The switch checks out giving 0.2 Ohms when on +/-.Everything checks out apart from the capacitor ,i am confused as to why my multi meter is giving a resistance yet no capacitance value.
I have followed yours steps and I am reading open loop across the motor and also reading open loop across the live and neutral of the plug any suggestions?
Hi Joel, have you have traced through the circuit as shown in the video? if you have an open reading across live& neutral you need to test each individual circuit but if you have nothing through the motor it does suggest the motor is faulty.
Thanks for the reply yes I followed through as you said it’s only across live and neutral on the plug and on the motor terminals I read open loop I suspect the motor thanks for your help and response
I have the Karcher k3.80. It has a slight oil leak on the base just above the motor. I can see four screws that hold this on. have not as yet removed them. is there a seal there. I don't have a parts manual to see the exploded view of the assembly.
Hi after 5 minutes of my Karcher being used the pressure seems to go down and it starts to smoke with smell of burning. Do you think this is electrical? Thanks
My Karcher pressure washer water is sputtering when I tried it today . Opinions would be appreciated . Is it water pressure or the pump maybe . Thank U.
Hi Bob, Try with another spray lance and make sure you have enough water pressure and flow from the hose to the machine, also check for any leaks that may be causing a reduction in pressure resulting in the sputtering.
Hello, I have a Karcher K330M. I was powering the house and the powerwasher stopped working. I checked the power coming from the house, it was OK. Water stills flow through the washer when the trigger is pulled on wand. I replaced the on/off switch last year. It still clicks on and off. Any suggestions on what to do next? Thanks
Hi mate. My karcher k3.77m is producing very low pressure, after using warm water. I changed the cylinder head bought on espare but still no pressure. Can you help me please?
Hi Khaleel, it sounds like an air block in the system so disconnect the high-pressure hose but leave the water hose connected and turn on the water but the machine needs to be unplugged, leave for about 5-7 mins then reconnect the high-pressure hose and squeeze the trigger to draw the water through and switch on the power and give it a try.
Hi i hope someone read my comment :) i have a Karcher K7.91 with a problem (ofcourse...) when i want to turn on the pressure washer it does nothing not a single turn ore anything, - i have checked the switch and its working fine - checked the cable - checked the capasitor no burn ore anything - switch is working fine ( tested it ) i think the problem is something like the motor but not sure do you have any idea ?? regards
hello. I have a karcher k5.85m plus, starts and trips circuit breaker...repeatedly...found sligh burn mak on the switch at the 2 metal connectors. I am not sure how the plate spring is situated on op the switch..(see #1 and 2 of electrical box at this site:
+philip magloire The exploded diagram does not show this clearly but indicates it is above the switch to push it either in position or 'towards' the switch 'buttons' to ensure they contact the control knob and shaft.
Hi Richard, it sounds like an air block in the system so disconnect the high-pressure hose but leave the water hose connected and turn on the water but the machine needs to be unplugged, leave for about 5-7 mins then reconnect the high-pressure hose and squeeze the trigger to draw the water through and switch on the power and give it a try.
I have a Karcher K3.68M When I initially turn it on the pump runs and build pressure till it cuts off. pull the trigger and it will relieve the initial pressure but the pump will not restart. If I hold the trigger and cycle the power switch it will run and give good pressure untill i stop and then will no restart until the power is cycled again. Any suggestions?
There are two switches so if the problem was one being a little lazy and sticking the machine should still stop. Disconnect and open the machine then remove the switches as shown here: th-cam.com/video/cEGv7s8aqpM/w-d-xo.htmlm51s then check if they are sticking when manually operated. If the switches look ok suspect the piston on the cylinder head that operates the switches may be sticking.
Hi Michelle, you need to gain access to find which component is causing the issue, have a look at this video to help th-cam.com/video/4WZgprLndhU/w-d-xo.html&t
eSpares I meant not in the cable but in the plug. Last test you doing is between neutral and live plug pols and you have reading 11.3 ohms I have 0. What dose it mean?
Hi Edgaras, O between the live and neutral means there is a break in the circuit, follow the procedure in the video from 2.44 as you need to test through the live & neutral side to determine the cause.
great videos! i have an older Karcger 320M It recently has an issue. When you plug it into an outlet, the machine is on in both the on or off position. The switch seems to be working ok, the knob hasnt broken What could be the issue?
The switch on most Karcher's works with the knob and the 'spill valve' that turns the appliance off even when turned on if the water is stopped by the gun. Check If this does not happen when you have connected the machine to both water and electricity and used until the air has been purged. Then check the switches are not corroded or stuck.
+eSpares ok so when investigating deeper, i found that there is a little red switch with 4 pronges coming off it. (karcher 320M) That switch does not operate properly. i took it apart, cleaned it, reinstalled and the pressure washer worked perfect. but after 10 mins of using it, it went back to the constantly on state again. so i think its safe to say i need to replace that switch! I believe it shorts out internally and does not interupt the current to the pump when the unloader valve kicks out. Thanks for your help.
If the machine does not hold pressure it will not auto stop. A damaged gasket will cause a leak and loose the pressure. If replacing the switch order a new gasket as well.
Any idea where the fuse would be on a Ryobi 1700 psi electric pressure washer? I took apart the plug but can’t seem to locate fuse, unless I don’t know what I’m looking at which could be possible... lol
Hi Cory, the fuse is in the plug and Mat show where at 1 minute in the video, in yours you may need to open the plug as it has screws holding together and it's inside.
eSpares I ended up just buying a new GFCI plug because my old one was cracked and it’s possible that it sustained water damage to the inside. I looked everywhere for a fuse on the inside and went thru the owners manual and couldn’t find any Info on checking the fuse in there. On your video it seemed to me the fuse was very easy to locate on the Home lite. Either way the plug head was cheap enough so hopefully this will solve the issue! If not I might have to run a few multimeter tests like in this video.. so do you set it to like OHMs 20k on the meter to get accurate reading since your measuring resistance?
Hi Richard, The problem is likely to be one of a couple of reasons. If water has got on the electrics it may have resulted in a partial short hence smoke. More likely is the motor capacitor has failed and requires replacing, for more information see this video: th-cam.com/video/cEGv7s8aqpM/w-d-xo.html
HI i have a K855 hs 240v washer on the wires for this motor i have 2 x white 1 x Yellow 1 x Black do you no what way it goes with the capacitor im lost on this one. Regards Paul
Not sure of the colours Paul but the motor on your machine is an induction motor. After the switch there are two winding that connect to one side of the power cord (Neutral) and the live goes to the one of the other wires and then through the capacitor to the other wire.
My pressure washer doesn't make a noise after switching on . When I turn the power on it use to kick the motor in then stop . Now when i turn it on nothing .
@@eSpares when your testing the plug you say because it hasn't changed it indicates a break in the circuit but my multimeter works fine and you never get a ready from the neutral and live. I don't know why
When Mat tests the pressure washer circuit on the live and neutral pins and you don't get a reading it indicates there is a fault somewhere in that circuit, so if you do the same test what do you get?
Your video was very informational and helpful. It was explained simply and got right to the point, short, sweet, and not confusing. Thank you
Glad to hear this helped. Thanks for tuning in!

Hi JR Check the circuit of the pressure washer first before testing the switch and the motor.
I tested everything like in the video and found that across the plug I have 0 ohms. Do I need all new cable?
Hi Edgaras, if you have tested through the cable and you have 0 ohms then there is a break in the cable and it would need to be replaced.
eSpares I meant not in the cable but in the plug. Last test you doing is between neutral and live plug pols and you have reading 11.3 ohms I have 0. What dose it mean?

i have an older Karcger 320M
It recently has an issue. When you plug it into an outlet, the machine is on in both the on or off position. The switch seems to be working ok, the knob hasnt broken
What could be the issue?
The switch on most Karcher's works with the knob and the 'spill valve' that turns the appliance off even when turned on if the water is stopped by the gun. Check If this does not happen when you have connected the machine to both water and electricity and used until the air has been purged.
Then check the switches are not corroded or stuck.

Thank you,i will do that today
Tore it apart, and found the triangular gasket torn. Would this be the reason that the machine wants to constantly stay on?

ok so when investigating deeper, i found that there is a little red switch with 4 pronges coming off it. (karcher 320M)
That switch does not operate properly. i took it apart, cleaned it, reinstalled and the pressure washer worked perfect. but after 10 mins of using it, it went back to the constantly on state again.
so i think its safe to say i need to replace that switch!
I believe it shorts out internally and does not interupt the current to the pump when the unloader valve kicks out.
Thanks for your help.
If the machine does not hold pressure it will not auto stop. A damaged gasket will cause a leak and loose the pressure. If replacing the switch order a new gasket as well.
Any idea where the fuse would be on a Ryobi 1700 psi electric pressure washer? I took apart the plug but can’t seem to locate fuse, unless I don’t know what I’m looking at which could be possible... lol
Hi Cory, the fuse is in the plug and Mat show where at 1 minute in the video, in yours you may need to open the plug as it has screws holding together and it's inside.
eSpares I ended up just buying a new GFCI plug because my old one was cracked and it’s possible that it sustained water damage to the inside. I looked everywhere for a fuse on the inside and went thru the owners manual and couldn’t find any Info on checking the fuse in there. On your video it seemed to me the fuse was very easy to locate on the Home lite. Either way the plug head was cheap enough so hopefully this will solve the issue! If not I might have to run a few multimeter tests like in this video.. so do you set it to like OHMs 20k on the meter to get accurate reading since your measuring resistance?
Hi Cory, it would depend on the component you are testing but start on the low scale and only increase if required.
eSpares ok thank you for your time!!
does the elect motor have brushes because mine is running 30 secs then smoke comes ot of motor .how do you disassemble the motor
Hi Frits, some have brushes what is your full model number?.
my karcher k4 started to smoke after 5mins use and low pressure any ideas if it's a goner or not?
Hi Richard, The problem is likely to be one of a couple of reasons. If water has got on the electrics it may have resulted in a partial short hence smoke. More likely is the motor capacitor has failed and requires replacing, for more information see this video:

Which motor use in pressure washer
I want to make pressur3 washer 70 bar to 90 bar
Sorry Aniket, we have no suggestions how to make a pressure washer.
Hi I have a sears pressure washer it builds up pressure then it shuts the motor off
then it's hard to start till it sits awhile like it pressure locked
Hi Donald, we do not have any information on the sears pressure washers.
HI i have a K855 hs 240v washer on the wires for this motor i have 2 x white 1 x Yellow 1 x Black do you no what way it goes with the capacitor im lost on this one.
Regards
Paul
Not sure of the colours Paul but the motor on your machine is an induction motor. After the switch there are two winding that connect to one side of the power cord (Neutral) and the live goes to the one of the other wires and then through the capacitor to the other wire.
My pressure washer doesn't make a noise after switching on . When I turn the power on it use to kick the motor in then stop . Now when i turn it on nothing .
Hi Jarrod, test the switch first before checking the motor and use the methods shown in the video.
I have a K4 premium eco it seems to leaking from cylinder head what do I do?

The cylinder head does crack if allowed to freeze. If this is the case it will need replacing.
Also my multimeter doesn't show any resistance on any plugs it's set at 200.... and on the right settings
Hi Frazzle, if you are testing components make sure you touch the leads together to test them, you should get a resistance through them.
@@eSpares when your testing the plug you say because it hasn't changed it indicates a break in the circuit but my multimeter works fine and you never get a ready from the neutral and live. I don't know why
When Mat tests the pressure washer circuit on the live and neutral pins and you don't get a reading it indicates there is a fault somewhere in that circuit, so if you do the same test what do you get?
@@eSpares no reading indicating a very high resistance... but that's the same of every plug I've tried lol
OK let's start at the beginning what is wrong and what have components have you tested.
Where's the capacitor?
Hi dacads, the capacitor on the K5 is located inside and usually fitted to the side of the motor.

Hi Fernando, sorry we are having trouble with your post, can you try again.
