SOURCE: 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.

Dewalt 3750 won't allow me to pull the chain to

Loosen the chain so it can be carefully moved by hand. If it moves pull out the spark plug. Sometimes oil and or fuel will collect in the cylinder and will cause this.

Where do you add the oil on a DeWalt 3100psi pressure washer?

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 )
Thanks for choosing FixYa,
Kelly

Starts but does not keep running. checked oil & its full. do you need water pressure at the pump? I know it has a low oil pressure cut off.

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.
