Karcher K2.26 Electric Power Washer - Page 3 Questions & Answers
I have a Karcher electric power washer. The
do you mean the gfci that is normally at the end of the cord or the switch on the unit itself. if its the ground fault circuit interrupter its detecting a short to ground and protecting you from recieving a shock.must inspect inside unit for possible moisture around motor or switch i don't think its overloading
My karcher seems to pulse
I do not have specific experience of your machine.
However, the high pressure pump will be controlled by a pressure switch on the high pressure outlet to the pipe and jet.
Pulsing (turning off) suggests that the outlet (high pressure) pipe is blocked or partially blocked.
Try checking the nozzle and (with the unit turned off) clearing it with a fine piece of wire.
Hope this works

Hi k2 series have alot of trouble does not always
HI This is caused either by a partially blocked nozzle on the end of your lance or the unloader valve sticking inside the machine. You can clean your nozzle by inserting a pin etc inside the end to clean it out. If this doesn,t work then it is most likely the unloader sticking. You need to remove the yellow cover and remove the unloader valve assembly.This is the bit that goes in and out when pressing the trigger. Remove this section then grease and oil the unloader and re fit. This should cure your problem.
Machine will not switch on
hell,machines dealing with water are having problems with powerswitches,the plastic hood covering the powerswitch might be broken and water might come in.Best thing to do, take the machine apart and look for rusty or wetted parts that should be dry, electrical parts that is..hoping to have helped youhugohugo.lindhout@ gmx.de
Where is the spill valve on my 3.550 pressure washer
The only washer that I know that calls their pressure control valve a "spill valve" is Karcher. On their 3500 units it is under a 3/8" cap screw... which may have a marker seal of yellow or red paint on it. Removal is best acheived by removing the cap with a screw driver, note the orientation of a small bushing and remove it and then turning on the washer, with water supply attached. Be careful to hold a small bucket over the hole as the parts will pop out. The spill valve is the most common cause of the pressure not "kicking in". The first symptoms are usually a hesitation to "kick in", progressing to.... not kicking in at all. Unless the spill valve is broken at the stem, it can be "rebuilt" by replacing the orings, cleaning the housing cylinder and re-lubricating with "waterproof" grease.
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).

The motor is pulsing on and off without the trigger being pressed
It is probably sucking air on one of the connections or around one of the fittings at the regulator. You can also turn the pressure up allittle on the regulator, that might stop it also. Make sure the clamps on the hoses going to the regulator is tite. Also it could be that the regulator is just bypassing water and if it has air in it it will pulsate.
When i switch my karcher on the motor makes o
This sounds like you may need a new capacitor. It is not a costly part to get. What the capacitor does is "jump starts" the motor so if it broken the motor will not start.
A test you can do is if you take off the front caseand then set the machine up as if you were going to use it. then when you turn on the machine quickly push the fan blade of the motor with a flat headed screw driver. If this makes the machine start to work, then you know that you need a new capacitor.
Just be carefull when doing the test.
Please remember to thumbs up :)
