Power washer not starting what type of oil to use dpd3100

These are the two simplest causes:
crankcase overfill situation . . check oil level and adjust as needed.
air filter blockage causing the engine vacuum to draw from the crankcase breather and the engine oil with it.

see if it has a low oil shut off and the oil is just at the level

In the Pump Dewalt recommends
DeWalt DP70 Pressure Washer Pump OilIn the engine Dewalt Recommends
SAE 10W-30 is recommended for general use

The pressure unloader us usually the first part/s that fail. An unloader can fail resulting in no or very low pressure or good pressure, however will not unload when trigger is released and stall the motor. Look at breakdown for your pump and determine if unloader parts are available and reasonable. If too costly to replace these parts then install an ez start valve to help start engine and tie back wand handle to deal with unloader problem (workaround). Ez start valve can be seen here:

When not in use, store washer with oil in pump to displace the water. The oil will help lube internal parts and possibly cause the unloader to begin working (if stuck due to debris/rust). You can find a gizmo to help you feed oil into pump on ebay /other web locations. Good luck with your repair.

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:

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,

There is a little window on the side of the pump to see the oil level but thats normaly the problem None of these companys make there owen pumps or engines i owen serveral power washers if you can tell me more about the problem Iwill likely know how to fix it see who made the pump and the engine and let me know pier_j

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.

Hi

Just try the following steps

• Inspect the water supply connections
• Inspect the drain hose
• Inspect the water pump
• Inspect outer tub for cracks or corrosion
• Inspect the tub seal
• Inspect the tub bearing

Good luck

Is there an oil sensor unit if it is going bad it tells the engine the oil low and engine wont start. I had same problem with my pressure washer, i just unplugged the sensor unit and it started fine ever since
