If your pressure washer turns off after it has been running for less than a minute, there are a few different parts on your pressure washer that may be causing the issue. Here is a quick breakdown of the top three things that could be causing your pressure washer to turn off after it has only been on for a few seconds.
The first thing that you need to check is your carburetor. When the carburetor on your pressure washer gets clogged, it can cause your pressure washer to power off shortly after it turns on.
It is easy for your carburetor to get clogged up. If you leave fuel sitting inside of your pressure washer in between uses, over time, the fuel will start to evaporate. When the fuel evaporates inside of your pressure washer, it leaves behind a sticky substance that can clog up your carburetor. When this happens, your pressure washer may turn on, but it will quickly power off.
In order to fix this problem, the first thing that you need to do is try and clean your carburetor. If that doesn't work, you may need to replace or even rebuild your carburetor.
#2. Fuel Filter
The next thing you need to check is your fuel filter. Over time, debris can build-up in your fuel filter. When your fuel filter gets clogged, it can cause your pressure washer to power-off because the fuel is not getting filtered correctly.
In order to fix this problem, you will need to drain all the fuel out of the fuel tank of your pressure washer. Then, you will need to remove the old fuel filter. You can try to clean it off, or you can replace it with a new filter.
#3 Fuel Cap
Finally, you need to check the fuel cap on your pressure washer. As your pressure washer uses fuel, air pressure has to be released from your pressure washer. There is a small hole in your fuel cap that allows the air and pressure that is building up to be released. If that hole gets clogged, your pressure washer will eventually turn off because there is nowhere for the air that builds up to be released.
Take off the cap and wash it. If you are unable to get the cap clean, you may need to replace the gas cap.
If your pressure washer turns on, but then turns off after only running for less than a minute, check the three different parts on your pressure washer described above. These are the three most common culprits behind the issue you are experiencing. For more information, consider contacting the professionals at Environmental Cleaning Systems.
