Dear mike husband,
One reasin for this fault could be a damaged lance or turbo lance. Try by replacing with new ones. If the problem is not solved, then the fault is due to a damaged spill valve. The spill valve could easily be damaged by using not suitable chemical or detergents. After using chemical detergents, one must always rinse the machine by passing pure water. The spill valve could also be damaged by leaving the machine for a long time with pressure in the system. One must never store such machines with pressure still inside. Always press the gun before storing.
Well the solution is to change the spill valve with a new one. In some cases even faulty suction valves can give this problem. But in the majority of cases it is the spill valve.
If you do not know how to fix this problem, it is better to be done by an expirienced technician.
Regards,
MG.

SOURCE: my karcher pressure washer has lost its water power

I have the same problem. With mine I have to remove the tip that I am using then pull the trigger and then replace the tip and pull and pressure should return. I believe that one of my valves is sticking causing me to reprime the pump frequently. I am trying to clean or replace my valves to fix the problem.

I hope this helps.

SOURCE: Electric Karcher pressure washer surging when turned on

Dear firenutt681,
One simple thing you can do, is to check for leaks. Check if hose at machine is leaking. Check gun if it is leaking. You can also check if water still comes out of lance nozzel. These leaks however so small, will cause the machine to surge.
Another reason is due to a faulty SPILL VALVE. This spill valve( often called CONTROL VALVE) will contract when the gun is closed. When it contracts under the enclosed pressure it will switch off the machine by means of a Micro Switch. Now if this Spill valve is faulty it will loose its compression under pressure and puts on the micro switch again. This can be seen once in a while or more frequent, as in your case. I sometimes do service Spill Valves, but mostly I replace them with a new one. I do not know the model number of your machine, but normally you have to open the cover and you should spot the spill valve on the head. Most probably you see a thick wire or a cap containing the micro swith. If you find the micro switch, you have found the spill valve. Sometimes it is a bit hard to pull out the spill valve. Myself, in various Karcher models I remove the spill valve by trying to feed water and put on a bit the machine. In this way the spill valve will be spitted out.
Another reason which makes your machine surge, is leakage from from the detergent inlet.
If you do not see no leakages at all....then for sure it is the SPILL VALVE.
If you cannot do this job yourself or you do not find spare parts...you can continue using the machine as it is...but before closing the gun...switch off the electricity. I only recommend this in an emergency. You do this so that you do not leave the machine surging. This surge will for sure damage the electric motor and the capacitor (assuming it is single phase).
Regards,
Fulltech.

SOURCE: Karcher 360M pressure washer pulsating problem when idleing

Hello,


unfortunately these little units have this problem commonly, 9 times out of 10 it will be the plastic head or the plastic valve block on the unit will be cracked and leaking slightly... it builds up pressure then leaks out and tries to build up the pressure again and this just reoccurs over and over...

you can get this repaired but is normally about half the cost of a new unit, if the pressure is still okay i would probably recommend just keep using it until it proper dies...

If you do get this fixed, we have studied into this and believe the main cause of heads cracking is warm water say if your inlet hose is in the sun for a period of time this can cause the water to become quite hot or if the unit sits and water trapped inside the head assy freezes can also cause this. Hope this helps Kind Regards Brad

Karcher electric pressure washer help starting


The test / reset buttons are for a Ground Fault Interrupter built into the cord / washer. This device will help prevent deadly electric shock in the event of a malfunction - it is the same technology used in "GFI" electrical outlets located in bathrooms, outdoors, basements, etc.

You should have this serviced - or replaced before using.

Good luck!

Karcher Leaking from Back or inside...Help please


Karcher pressure washers are very sensitive to over-winter freezing. The plastic parts break, and you have to replace all of the leaking parts.
You may be missing a locking tab, without seeing the thing apart next to the exploded parts view, it's really hard to tell. Search google for "karcher parts", and put in your model number...

Operating Manuals Karcher 302 presser washer


do you want a "how to use the machine" or "parts diagrams" or "how to repair" ?

"how to use" is the same for all pressure washers...........

i guess you own a KB 302 1.994-923.0 but karcher dont list this "operators manual"

this is for the k 370 :
http://www.sparesgiant.com/media/import/karcher/k370%20op%20man.pdf

If you have a Karcher then you should always post your machines barcode.
The karcher barcode is on a silver sticker and is usually 15 digits long. Example 156987400000123 is actually model 1.569-874.0 and serial number 00123....

I can't connect the garden hose to the water inlet. I am using a size 5/8'' hose but it wont connect to the unit. Please help!


Karcher electric pressure washers typically are supplied fitted with the male half of a standard Hozelock connector. You need the female half secured to the end of your hose, and then they just click together.

How do i know if my outside tap has a non - return valve i want to start using a pressure washer


Dear del_brenda_s,
I have been servicing Power Washers for the last 5 years. And I cannot understand why you need a non-return tap outside. I think "outside" you are refering to the main supply after the water meter.
Well if your power washer needs a non-return, you can fit a cheap garden hose non- return attachment.
Regarding the non-return at the outside tap,..this is most probably NON-RETURN. If you want to be sure you can contact the water works division of your country and city...and I am sure they know what sort of taps should be used. In my country it is a must that a non-return outside tap is used. This is important so that when there is a cut in the water supply, the water meter and the whole system will not have to be bled out of air when the water comes again.
Regards,
Fulltech.
