SOURCE: cannot get it to uptake the bleach for spraying

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?

SOURCE: DPD 3100 gas pressure washer.

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.

SOURCE: Hi, My Dewalt 3100 pressure

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.

Hi, I have a Dewalt pressure washer 3100 psi. I want to know why the pressure washer works okay for 1 hour then it stop working completely. the oil is fine, the spark plugs are okay, and when I tried to...


There are two common issues that will cause what you are describing. What you need to do is run the machine until it dies as you are describing. Then pull the spark plug and check for spark. If you do not have spark you have a failing stater. It is very common for this problem to only show itself after the machine warms up. If you find that you do still have spark try removing the gas cap and restarting. It is also common for a vacuum lock to occur due to the seal on the gas tank cap. In most cases one of these will be your issue. If not feel free to contact me at 800.247.8103 and I will help you to troubleshoot the issue further.

Dewalt Pressure washer keeps shutting off for no reason. plenty of gas and oil, water running to it. starts fine and as soon as I start spraying it shuts down.


Had a similar issue with my dewalt 4200 pw. Unit starting shutting off after spraying for about 5 min. Then difficult to restart, but would start again eventually only to shut down a few min later. Had new engine oil, new pump oil, good gas. I changed the spark plug and unit runs great again!

Does briggs and stratton make the engine for dewalt pressure washers


If it is a DPH it has a Honda engine. If it is a DPD it has a Dewalt engine that is made by either Honda or is a Chinese copy of the Honda engine. I looked at a photo of the engine and it looks like a Honda engine not a Briggs engine. Look on the engine data plate and if it says Made In China it is a chinese copy. If it say's Made In Japan it is a Honda. Some Briggs engines are made in China also so it is hard to tell except by the looks of the engine. The Chinese copy of the Honda engine looks exactly like a Honda.
