Burner & Engine Components FAQ's
When should electrodes or the flame sensor be replaced?
Replace damaged, cracked, or heavily worn electrodes and any sensor with a cloudy or contaminated window. If starts are inconsistent after cleaning and setting gaps to spec, replacement is often the next step.
How do I prime a burner fuel pump after a filter change?
Fill the filter, ensure all fittings are tight, then follow your manual to bleed/prime the pump until a steady fuel stream is present before lighting the burner.
Do I need a 12V or 120V igniter/transformer?
Match the power your burner is wired for. Machines with charging systems often use 12V DC; shop or stationary units frequently use 120V AC. Check the label on the existing part or the wiring diagram.
Can I run diesel or kerosene in my burner?
Many oil‑fired pressure washer burners are designed for common heating fuels such as diesel or kerosene, but always follow the fuel types listed by your machine’s manufacturer.
My burner smokes—what should I check first?
Verify clean fuel and filtration, confirm the nozzle is not worn, and ensure the blower wheel and air band are clean and set per the manual. Persistent smoke warrants a deeper inspection before use.
How do I choose the correct burner nozzle?
Match the GPH rating and spray angle stamped on your current nozzle. If the stamp is unreadable, confirm the size listed in your unit’s manual or contact our team with your model/serial number.
What does the burner on a hot water pressure washer do?
It atomizes and ignites fuel to heat the coil so your water rises to the temperature set by the controls. The burner works with a fuel pump, blower, igniter/electrodes, nozzle, and safety controls.
