Having problems with your Dewalt 3800 PSI Pressure Washer ?

Dewalt 3800 psi

\015 This is the second 3800 dewalt in 2wks I have made sure its getting at least 5gpm by timing 5gal bucket fill over 5gallons in under 40seconds and made sure pump was full before startup it worked great for about 1 hr then it did the same as the last one when trigger is pulled it had a 30 to 45 second Delay now its longer could this be a bad run on pumps BTW it has a AAA pump not a cat thanks Joe.\015

Answers :

It's the gas cap. The cap won't vent and it causes a vacuum in the tank and won't let fuel get to the carb. Crack the gas cap open enough to let some air in and run it like that. If it solves your problems then you can get a new cap cheep. I had the same problem with mine.
You checked the output to measure 5 GPM? How are you feeding that unit? What are you using for detergent? Have you adjusted the bypass valve?
