Top 20 Karcher PSI Electric Pressure Washer Questions & Answers

most likely motor or pump overheated and seized or burnt out remove cover to the unit and test for motor operation

if the oil has water in it there is more then likely a seal problem and if there is a sight gauge on the oil reservoir it should be no more then half way

When water is running through system, the motor has to run to keep the pressure built up. So, if the water is leaking out, the motor think it needs to keep running to keep the pressure built up. The leak needs to be fixed to the motor will not run constantly.

Check the power cord from the end where you plug it in all the way to where it wires into the switch and check the switch also! They are notorious for going out! Best of luck!

The "manifold" as talked about above is also called the "Control head". For a picture of the very small cracks in the control head see here: Karcher Control Head cracks The video linked to below talks about the cracks in the control head at 7:00 through to 7:08. They guy incorrectly calls it the cylinder head in the video. How to FIX Karcher pressure washer If Karcher made the control head from an aluminium casting, or used a metal insert near the point of failure, their product range would be a LOT more reliable.

So when you are using the machine & keeping the trigger pulled open the machine builds up to pressure then knocks off all the time. If this is so the machine is not at fault & is doing what it is meant to do & protect its self from over pressuring & the fault is in the nozzles you are using. You need to check the nozzle size is correct for the machine & also airline the nozzle to clear of any dirt. Thanks qwashers

Two potential problems, notwithstanding complete failure, faulty cord, faulty plug, faulty electrical outlet. All of the above need elimination before attempting the following: 1.) A faulty on/off switch. You will need a multimeter to test for continuity. Not a task for those not competent. 2.) Faulty control head which is not telling the motor to turn on. A valve is stuck in the head and the machine does not know that you want to use it.It thinks that you have triggered off and has stopped. Probably a job for a specialist. Definitely not a job to tackle without a spare parts breakdown. Please, everyone..... DO NOT MUCK AROUND WITH ELECTRICITY IF YOU ARE NOT COMPETENT. MAKE SURE THAT YOU HAVE AN EARTH LEAKAGE DETECTOR BETWEEN YOU AND THE POWER SUPPLY

I fixed mine works good easy too watch my video step by step i put it on youtubehttp://www.youtube.com/watch?v=UFXSLOBL0Mg

Bearings are standard, If you can remove the bearing, take it to any bearing supplier and they will give you the requires bearing. Specify that you want a 2RS bearing, one that has rubber seals on both sides of the race if the original one was not like this. (Look for signs like SKF, Fafnir, Timken, etc. There are also numerous Japanese and Chinese makes, but in a wet application, rather go for one of the others mentioned).

there should be a ball check valve in the soap suction hose lets soap in keep water out poke a paper clip in the hole a few times soap will build up there and make the ball valve leak

The pressure drop on this unit is normally caused by failing water seals in the pump. In order to repair it you will need to purchase a repair kit for the pump and rebuild it.

Normally when you dry run a machine you damage the pump so it would probably need changing. The motor might be Ok but for you to fix it you will need to take it to a Karcher dealer/service center.

From experiance it sometimes can be more cost efficient to purchase a new Karcher machine and get the 12 month warranty than spending money on an older machine.

I have a larger gas powered karcher, just make sure the water going to your karcher is not obstructed from its path. on mine i bought a goodyear hose that can be purchased at northern tools or any hardware store. and use it just for pressure washing. good luck!

you will have to take the cover off & look for melted wires or a fuse.
if there is no fuse the capacitor may have been cooked.
it should be a white cylinder.if it has been damaged it will have burn marks and may be swollen.
replace the capacitor and it should start.

hi,
make sure everything is clean;the inlet screen etc. Take a flashlight and look inside were the hose connects and make sure nothing is inside.To do a simple test;connect the hose,turn on the water,and WITHOUT starting the pressure washer,squeeze the trigger on the gun;you should have a steady stream of water coming out,about the same as a kids water gun;like a super soaker;If not,then your problem is something is restricting the water inlet,or if the washer is old,mineral deposits inside a passage.If it does squirt out pretty good,then your washer is tired,or you used a cleaner that's NOT compatible with pressure washer seals,or maybe the unloader is stuck,and won't allow the washer to build pressure...........If it's getting a good supply of water,the only thing that builds pressure is the seals,and the unloader.Other than that,there is a small passage were the outlet is,and that could be restricted with mineral deposits,but I would take apart the hose and check for debris in the line,to be sure Hope this helps!!

The cover of the detergent tank is at the top of the machine just below the handle.

The manual is available here:

Check that your are getting proper water pressure. Also check filter going into the machine where the hose connects sounds like the washer is not getting enough water pressure.

It is not clear what type of machine this is you are having trouble with but I would guess it is not a chainsaw but a pump like a pressure washer pump.
Pressure washers today are very picky about what goes in them. If it was just water you may have corrosion in the pump. especially if it is an aluminum housing. It is never recommended to run harsh chemicals through the pumps. Briggs and Stratton makes a pump saver recommended for storing your pump. You can purchase this pump saver or parts for your machine through dealers such as www.arcolawn.com.
If you can reply with the type of machine and any numbers you can find I would be happy to assist further.
Thank you -Joe

if the hole is in the gun hose then no.
it will need to be replaced. try bunnings warehouse.
you may need to purchase the gun & hose together.

From what you have explained it sounds like the capacitor for the motor is bad. The capacitor is what gives the motor the extra kick to get up and moving when you flip the machne on.

To fix the problem you are going to have to replace the bad capacitor that you have, the part number that you need is 66611960, price is $30.77. If you are interesting I can get you one, send me a email at [email protected]
