Hi, My Dewalt 3100 pressure washer pump wash leaking water from a check valve or overflow plug Do you know whats wrong?

The Dewalt 3100 came with 2 different pumps. The Blue Cat pump and the oil free pump that was made by DeWalt.
You may just have a bad Thermal relief Valve on the unit.

You can find the parts diagram at www.allpartsinc.com

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.
Thanks for choosing FixYa,

Using a garden auger with the torque set to the highest setting the clutch broke and started to slip. Is this too much for the Dewalt 720 cordless drill? Dewalt is repairing it under warranty.

Yes, luckily Dewalt is taking care of you. You might want to look into a 1/2' drive electric model (sorry with a cord) Alot depends on how hard the ground is but in the long run the big electric will handle about anything you throw at it. Check Sears or Home Depot both good sources for good tools

Cannot get it to uptake the bleach for spraying Dewalt pressure washer 3100 psi

On most pressure washers you wont be able to draw soap/bleach into pump unless you are spraying on low pressure.There is a valve on the inside of inlet hose fitting that closes when high back pressure is sensed.Would it draw bleach into hose when wand tip is removed?
