20 Most Recent Karcher PSI Electric Pressure Washer Questions & Answers


Could be the input water pressure is not sufficient. There is a pressure valve inside the machine that will cut off the motor if input pressure is too low or non existent.

Try a different source for the water input.

Dear Robertkoch,
These type of wands are throw away type. The water could be leaking from the hose with the wand. It could be leaking from the valve. That is the valve is not closing when trigger is not pulled. Myself even when a wand (gun) is serviceable...I do not find it worth it fixing it. The wise thing to do is buy a new one. But if you wish to experiment and drill the rivets...and by any chance you fix the problem...then good luck for you. If you decide to buy a new wand...buy exactly the same as you have, so maybe you might use a spare from the old one for the new one when the time arrises.
Regards,
Fulltech.

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.

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

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!

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.

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.

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.

Most pressure washers have ball lock type fittings on the hose connections. What happens is the little steel balls get a bit of corrosion and do not lock the male fitting properly with the female coupling. Load up the fitting with some Oil or WD 40. Then connect and disconnect the fitting several times to losen up the balls and springs. Should the spring in the coupling break you will get the exact symptom your describing.

If the OIL / WD 40 does not do the trick then you may have to change out the quick disconnect coupling.
