Pressure washers are powerful machines running on electric motors or gasoline engines. Like any other machine, there can be malfunctioning or problems working the pressure washer. If you have been using your pressure washer for a long time, you must take good care of it because, with time, the components in the pressure washer get worn out, and they are more prone to damage.

Smoke from the pressure washer is not a good sign, and you should immediately turn it off. Smoking a pressure washer generally means an internal fire or a fire hazard. If you are facing similar problems, then this article will help you.

This article will discuss the causes of smoke in pressure washers and how to solve it. So let’s get started!

Why Is My Pressure Washer Smoking?

If your pressure washer is smoking, there can be various reasons behind it. The most common reason for smoking is inappropriate fuel burning or insufficient oil in the gas pressure washer. Some of the other reasons are:

  • Overheated motors can also cause smoke in electric pressure washers. They overheat causing the winding to melt, which results in smoking.
  • The smoke can be steam due to water leakage to the engine or motor, where it gets heated and creates smoke. This problem can create a lot of other problems.
  • Mixing the oil in the fuel can also cause engine smoking, leading to total engine failure.
  • Overheating of internal plastic components can also be the ultimate cause of smoking.

As you can notice, the major cause of smoking is overheating.
