unloader can fail resulting in no or very low pressure or good pressure, however will not unload when trigger is released and stall the motor. Look at breakdown for your pump and
determine if
unloader parts are available and reasonable. If too costly to replace these parts then install an ez start valve to help start engine and tie back wand handle to deal with
unloader problem (workaround). Ez start valve can be seen here:

When not in use, store washer with oil in pump to displace the water. The oil will help lube internal parts and possibly cause the unloader to begin working (if stuck due to debris/rust). You can find a gizmo to help you feed oil into pump on ebay /other web locations. Good luck with your repair.

Hi and welcome to FixYa, I am Kelly.
I note that your question was 3 months ago. I answered a current post today that had your exact same symptoms. Your post was revealed after I answered the current post. Had I seen your post 90 days ago I would have responded with the same answer as follows:
There is a low oil level sensor on the opposite side of the engine as the oil fill / dipstick. The next time that your presure washer acts up disconnect ONE wire to the oil level sensor. On pressure washers mose engines have the oil level sensor removed for just this reason. You tip the engine to move the power washer and you can not start it or.. if you move it with the unit running the oil level sensor kills the ignition. Just make sure that anytime you are going to use it that you ensure the oil level is properly serviced. (Each use)
There is yet another possibility. Debris in the bottom of the fuel bowl will draft directly into the lower fuel jet (Located inthe bowl nut area) with a tip of the unit and clog the fuel nozzle. You can prove you have a fuel problem simply by adding gas to the carb throat with the air filter removed. If you get a brief start... you have a fuel not a spark problem. Turn off the fuel selector... remove the fuel float bowl nut and drop the float bowl. Use carb cleaner in the threaded area to clean out the orifice in the body of the carb and then remove the debris from the float bowl. CLEAN the bowl nut also.
Use a spray can lid for the next step under the float bowl area.
BRIEFLY
Open the fuel selector and gently lift the float to level. Fuel must shut off when near level and re-start fuel flow as you lower the float. The spray paint can lid should fill up in 8 seconds or less. If you have poor fuel flow start looking at the bottom of the gas tank or an inline fuel filter as the problem. Some fuel selectors have tiny bowls under the fuel selector lever. Make sure to clean this out also if you have one.
Turn off the fuel selector. Reinstall the float bowl making sure the rubber bowl gasket is fitted properly. Fuel selector ON... leak test. Then test start the unit and see if your symptom is gone.
One more possibility. Your engine has and E-Z start valve that is supposed to be a compression relief. If this is sitcking / partially open ect.. it can make it hard to start your engine.
I really think you have a low oil level sensor issue that is grounding out the spark because it cycles to ground when you move the unit and is not... sensing the oil level properly after you move the unit. I clean oil level sensors with carb cleaner. You can wake up about 75% of them just by cleaning them off internally through the 2 side holes cleaning up to the contact area on the top of the sensor.

I have a Dewalt DPD3100,
Take the hose off the gun and see if water comes out. If so the gun has to be taken apart and cleaned. Also where the water hose goes in to the machine there is a screen filter which you might have to clean if water is not comming out on the gun side. Use a screwdriver and pry it out carefully around the edges Clean the screen with a wire brush and put it back in and try it.

The coupler that the nozzle goes into uses a 1/4" EPDM o-ring. This o-ring needs to be replaced. You can find them at most major hardware stores or purchase them by contact us at 800.247.8103 or visiting www.landanw.com.

Hi and welcome to FixYa, I am Kelly
From reading everything I can find, i.e User's manual & parts manual the only thing you add oil too is the engine. The pressure pump does not have a liquid sump.
You can look at parts here detail D:
http://www.ereplacementparts.com/dewalt-dpd3100-pressure-washer-parts-c-1009_7440_7445.html
So too add oil to the engine you would remove the dip stick from the crank case located on the opposite of the side of the engine as the oil sensor.
I recommend you use 30 WT SAE oil for 3 oil changes then on the 4th oil change use an HD 30 WT oil. The oil drain plug is located in the center of the side of the engine crank case base. On the 5th Oil change switch back to SAE 30 WT oil. Oil brands are not really important. They all have to meet SAE the same standards to carry the label of SAE. (Yes you can use a generic 30 WT SAE oil )

I ran my pressure washer today in an effort to run
It looks as if moisture/water has contaminated the oil. Check the level of oil from the glass window. It must be high. Drain out the oil & check if water is present, if so then replace the entire oil.
How do you check oil in pump on Dewalt DPD3100
There is a little window on the side of the pump to see the oil level but thats normaly the problem None of these companys make there owen pumps or engines i owen serveral power washers if you can tell me more about the problem Iwill likely know how to fix it see who made the pump and the engine and let me know pier_j
Starts but does not keep running. checked oil
First: check and change the spark plug and do a oil change (OIL IS NOT THE PROBLEM BUT IS GOOD TO DO IT) then do a test with fresh gasoline.
Second:check all fuel components (LINES,CARB,ETC...)
Third:if any of this fix the problem your machine need service.
