If your machine smokes like the one in this photo, its time for a burner tune up and adjustment! Smoking pressure washers indicate the machine is not properly burning the fuel. When fuel is not burning correctly the unit will build up soot in the coil. Soot build up on the heat exchange coil is a symptom of an ill-maintained burner.

Soot causes a whole list of problems, including difficulties with draft, efficiency, and carbon monoxide. Soot plugs the coil and reduces the airflow which in turn, reduces the pressure washer’s efficiency and overall equipment life. As soot builds up on the burner coil, fuel consumption and cost increase. Soot buildup can be avoided by considering these factors:nImproper Voltage: Low voltage will affect burner performance. Adjust the RPM for proper voltage (gas engines).

Professional preventative maintenance is strongly recommended bi-annually for all pressure washer burner systems.
