SOURCE: I was using the pressure washer and it stopped

This problem, where the unit continually switches on and off when the handgun is closed, is quite common. Unfortunately it has at least six different possible causes, only two of which are easily checked. 
The first thing you can do is look for leaks.  Even the slightest leak will cause this pulsing because the unit gets up to pressure, switches off, loses pressure, switches back on again, comes back up to pressure, switches off... and so on.  This repeated switching is not good for the motor and should not be allowed to continue for longer than necessary to observe what's happening.
So... 1. Does the handgun shut off completely, or does it drip? If it drips, it may simply be because a seal has failed. The handgun can be dismantled, checked, and any defective parts replaced; be sure to lubricate O-rings with silicone grease when reassembling. As a last resort, the whole gun may need to be replaced.
2. Are there any visible leaks at the high-pressure hose screw connections?  If so, most likely an O-ring needs replacing - again lubricate the new one well with silicone grease.
3. If there are no visible leaks, either from the gun or from the connections, all other possible causes are internal within the cylinder head or control head of the pump. New parts will be needed and this normally calls for a professional repair, although it's not beyond the scope of a truly competent amateur.
I hope this helps. Any further questions, just ask! Please remember to rate this response.

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.

Remove the hose and run the machine. If the machine works and the flow of water is ok. Start checking the hose for a restriction and trigger. Make sure this is correct before you start taking the pump to bits

Where do i get a 2200 psi pump?


It depends on what you want the pump for, but at 2200 psi, I presume you are looking for something like a pressure washer pump.
Harbor Freight sells a 1600 or 2500 psi pressure washer

http://www.harborfreight.com/2500-psi-3-gpm-65-hp-212cc-pressure-washer-69734.html

If you need just the pump, here are a couple of websites to check out:

Pressure Washer Direct
http://www.pressurewashersdirect.com/power/pressure-washer-pumps.html

Northern Tool
http://www.northerntool.com/shop/tools/category_pressure-washer-accessories+pressure-washer-pumps?utm_source=Natural&utm_medium=Covario&utm_campaign=Pressure

And you can check on Amazon or eBay and see if someone is selling one there.


Good luck!

I was unable to get the water through the hose, but it did run freely from the washer with the hose off. I took the wand/handle apart to clean it and I am now unable to generate enough strength to compress...


Hi Bill,

Yea, I've had that same problem. What I have done is to put the spring in a vise to compress it, then tying the coils together with some thin wire, putting it on the "tool", then snipping the wires.

I hope this helps. If it does, I'd appreciate your vote. Thanks,

My Karcher K9.8 electric pressure washer started


Not Simple.
I have the same Problem, the leak is from the seam of the Manifold or on the pressure side of the Pump and the hose housing. In my case there is a small crack in the seam of the Manifold Housing. A manufacturing defect.. A New Manifold Complete Replacement about the half the price what I paid for this pressure washer at Walmart... :( If under 1 year old, and you can find a receipt,Karcher will replace the whole Pressure washer under warranty.
