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.

DPD 3100 gas pressure washer. No water going through pressure washer. Have taken screen completely out and still no water moving through

See this diagram:
http://www.mastertoolrepair.com/images/DPD3100_pump.jpg?osCsid=1f3m03ijp5lcht6569kran6rk2

Remove Items 122 (Un;loader) and 138 (Thermail relief). Clean them up as best you can with a nylon brush under some slow running water. Dis-assemble the unloader valve completly to clean (both ends). Then lubrcate them with White Grease and reinstall both parts AFTER placing White grease in the cavity the valves mount into. Very briefly... Test water flow with the engine not running Then start the unit with water off and let run 30 seconds. Turn off engine. Turn ON water supply and test water flow engine OFF. Note you will get a certain amount of white grease initially that passes through the unit. Start unit and rapidly actuate the trigger 1/2 second on 1/2 second off multiple times to force the unloader valve to cycle.

You can get parts here if either of the valves have completly failed:

The above steps should get your presure washer working properly again.

I have a Dewalt DPD3100, 2 yrs old, never had any problem, water supply hose is attached, water is going in but no water out?

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.

The trigger on the wand does not work. Water comes out of the wand automatically.

What's the rating on gun? Sounds like the gallon per minute volume may be too great.
