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: I have a karcher 2400 psi pressure washer and it

the most comon problem with thease is a stuck bypass valve, this is the valve that alowes the water to bypass round the pump when the triger is closed, when they stick all of your pressure runs around the pump and not out of your nozzle,,
its located in the centre of the pump on the top, undo the 2 cap screws pull out valve greese and re fit

SOURCE: karcher pressure washer trigger problem

The wands that it will not run with would most likley have a little dirt in the tip of the nozzle. This would not allow the water to flow through in turn activating the pressure switch and shutting the machine down

Make sure you DO NOT have a check valve (this is what stops your hose running when you disconnect from the hozelock fitting) in your hose pipe system, This will send a shockwave through the pressure washer and destroy the fitting you mentioned. They can be easily removed.

Doesn't stop spraying after trigger is released


Dear Peggy,
You can have a problem with the valve at the gun which is sticking open. This valve can be OK without pressure, but with pressure it can stick open. It is very easy to make sure, by attaching a good gun or a new gun. In simple words...replace the gun.
Regards,
Fulltech.

Water leaking from spray gun


It depends on were the water is leaking from on the gun. If the water is leaking from were the high pressure hose goes into the gun it could be that on oring as been damaged. If the water is coming from the trigger you may need a new trigger gun.

If you tell me your model number (1.xxx-xxx.0) i can tell you the part number that you will need to give to your Karcher dealer/supplier to replace it.

Engine runs , not getting any water flow when trigger pressed.


Disconnect hoses.
Look for kink in water hose.
Check incoming water connection for filter washer
Replace filter washer
If you don't have a filter washer, put one in.
Hook up water, and turn on
Water should come out other side of pump.
Turn on machine.
Do you get pressured water out of pump.
If no pressure, then pump is suspect
Hook up washer hose without gun
Does pressure come out of washer hose
Finally, the gun trigger may be bad.

We had to buy guns now and then.

Why dose my Karcher K2.35 keep blowing the gun hose off?


There is a good chance you are missing the black plastic clip that holds the hose into the trigger gun. If you look at where the hose goes into the gun there should be a flat slot where a black plastic clip would slide in and keep the hose into the trigger gun.

The handle leaks and seems to not have the tension on the handle. I have it apart and it seems like a tension string is broken but I can't see how it reconnects.


They don't offer parts for the trigger guns, you would just need to purchase a new trigger gun. There is a number of different trigger guns for these machines though, what is the model and part number of the machine that you have?

The valve that admits more water to be compressed is stuck. It is likely the O-Rings on it need replacing. No water to the pump, no pressure!

The motor will stop when pressure is up to the designed pressure.

Trigger gun


It sounds like you left out the spring in the hose.
There are about 10 different models of K330 with several types of guns. Go here and search until you find the correct gun so you can see the diagram. I think it will be hard to buy a replacement spring, though.

Karcher K 3.68 M operation


These units have pressure valves that automatically turn off the pump once the pressure is high enough. The pressure switches do fail and sometimes stick and act as you've described.
