I had to take apart the handle of my Black & Decker 1550 PSI Electric Power Washer ( Sears Item# 07175293000 ' Model# 11BLE-105) because it was jammed. When I did so, two springs popped out. One is short and squat and the other is longer and thinner. I know they control the trigger but I cannot figure out where they go.

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: karcher 1650 leaking water from trigger
i believe the spring is the actual trigger spring that pushes the trigger switch back in place and the water leaking out is probably a seal issue
SOURCE: i have a black & decker pressure washer model
check the unloader valve (pressure relief valve) probably need to replace the o-ring. it should be on the side of the pump and have a large spring. just unscrew and replace.
hope this helps.

thats normal, it is reducing the built up pressure that is not needed until the trigger is pulled.
Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c
SOURCE: black and decker electric power washer nothing coming out of wand all water coming out trigger.
Either the pressure tip or wand are blocked or the valve in the trigger is broken. Remove the high pressure tip and either try another tip or pull the trigger without a tip on the wand to see if you have the same problem. If available, try another pressure gun on the hose.
