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.

Make sure that while you are running your pressure washer, other machines that pull

large volumes of water like a dishwasher or washing machine are not running. check and make sure

the hose you have tied to the pressure washer is not collapsing or has any kinks in it.

check the filter where your water hose ties in to your pressure washer, make sure it

is clean and does not have any debris or hardwater buildup, clean the tip at the tip of

the wand. if it is reduced in size by hardwater buildup, will not work properly, good luck!

No water coming through pump at all.


Is the tip/nozzle clean? try a different one. But you're probably right about the pump (I think they are all junk) unless you spend over a grand and get a "real" one

i don't know what a car boot sale is but sounds as if relief valve is stuck open.if this car boot thing is a car lot they use all kinds of stuff to clean cars in the water they use to wash a car. this washer has probably been let set up without being flushed after use. the problem isn't in the pump most likely but a corroded relief vale. remove and clean.
