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: Hi, I have a Dewalt pressure

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.

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.

What oil to use


Your manual will say to use General pump oil GP100..or whatever DeWalt's number for that may be. See dewalt.com for their proper part number. From the pictures of that model I see on line, that is a General Pump and they have recommended Non-detergent 30w standard motor oil in the past. We like to use a non-foaming full synthetic 20-50w racing oil on these high RPM pumps.

Engine is difficult to start when cold
  1. Check the battery condition, battery state of charge and starter motor current draw. Replace the battery if marginal and the starter motor if the current draw is beyond specification.
  2. Check the battery cable condition. Clean the battery terminals and replace corroded or damaged cables.
  3. Check the fuel system for proper operation. A fuel pump with insufficient fuel pressure or clogged injectors should be replaced.
  4. Check the engine's tune-up status. Note the tune-up specifications and check for items such as severely worn spark plugs; adjust or replace as needed. On vehicles with manually adjusted valve clearances, check for tight valves and adjust to specification.
  5. Check for a failed coolant temperature sensor, and replace if out of specification.
  6. heck the operation of the engine management systems for fuel and ignition; repair or replace failed components as necessary.
Engine is difficult to start when hot
  1. Check the air filter and air intake system. Replace the air filter if it is dirty or contaminated. Check the fresh air intake system for restrictions or blockage.
  2. Check for loose or deteriorated engine grounds and clean, tighten or replace as needed.
  3. Check for needed maintenance. Inspect tune-up and service related items such as spark plugs and engine oil condition, and check the operation of the engine fuel and ignition management system.

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!
