Hi Your problem is your unloader pressure valve switch.It is a cylinder that moves up & down inside a housing,. activaded by water pressure.Inside the cavity of the housing is dirt on the wall of it.Thats your problem.Once you clean the cylinder wall & apply some water grease ,problem gone.Your problem is not the switch.

SOURCE: honda pressure washer cuts out when lance trigger released.

You most likely need to set your valve clearances. If it is hard to pull over or the recoil snaps back after starting your valves need to be set for sure. This may not be the entire problem but it is a good start. Also change the spark plug, a bad plug will cause odd problems and is too cheap not to eliminate as a source. In addition check your fuel, pour a little out into a white container (I like spray paint can caps for this) and look at the color. If it is yellow to orange it is bad. You can pour it into you car, the car electronic sensors will compinsate for it quality but a small engine can't. Use a NGK BP6ES or BPR6ES plug.
You need:
Feeler gages
10mm open end wrench
14mm open end wrench
1 long shaft screw driver or rod
1 spark plug socket and ratchet

Remove the spark plug and the valve cover. Pull the recoil over slowly until the intake valve opens (intake is closes to the carb and it will go down when it opens). Now put your long screwdrive down the spark plug hole. Slow pull the engine over until the screwdriver handle is at it highest point, this is top dead center. It may take a few attempts. Now check your valve clearance between the rockers and the top of the valve. The intake should be .006 and the exhaust .008, both can be +/- .001. To adjust: hold the large nut with the 14mm then loosen the small one with the 10mm. Lefty loosey. Now turn your large nut until you get the correct setting and then tighten the small one the lock it in. It may take a few attempts and alway reverify your setting after you lock it down. Once done, find top dead center again and reverify. Now your valves are set.

SOURCE: pressure washer stalls out when wand nozzle is released

common for not starting unless trigger engaged as you are turning the pump as well as engine creating pressure,as for stalling pump has unloader valve which is probably in need of grease(use good silicone grease)this allows water to ciculate when trigger released.

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.

Electric pressure washer wont start


Gail, check the cord/plug for any sign of breakage, probably either switch has gone bad or motor faulty, have tested by a small appliance repair/ vacuum repair shop as they are usually the most reasonable priced.

My electric Campbell hausfeld 1750 psi won,t always start when I pull the trigger .sometimes it will quit while running. the motor and pump seem to be free. it works good while it is running. CR


Hi , i'm not familiar with the machine so without model numbers it is hard to diagnose.
if it is a trapped pressure unloader valve, ie the motor turns off when you let go of the trigger , then it is possible for it to be a pressure switch causing problems. the pressure switch may turn it off immediately you let go of the trigger or it may have a delay stop on it, where it will turn it off after a predetermined time interval. it is quite common for springs to break or microswitches to fail in these switches.

HI Your machine wil start and stop if you have any external leaks when the machine is running at not pressing the trigger. Please start the machine and not pull the trigger and look form leaks. A common one is around the high pressure hose outlet and also the trigger.
