Why my pressure washer runs for about 5 minutes and dies out
Ronald For model number EXWGV2121 - March 28, 2023

Hi Ronald, Thank you for your question. If your pressure washer has not been used for awhile and it runs for a few minutes and stops, it may be clogged. If fuel has been sitting in the pressure washer for a long time, it becomes thicker. Once the compressor is turned and fuel starts to go through the carburetor, it becomes clogged. If it is clogged. the carburetor will need to be cleaned or replaced. We would also recommend checking the fuel cap, the fuel filter to see if they are also clogged with fuel and check the air filter, the pre cleaner and the spark arrestor as well to see if they are clogged and need replacing. Once you have determined the part you need, please call customer service. We look forward to hearing from you!
