  If your Simpson Pressure Washer's engine won't start, several factors could be at play. First, ensure you have fresh fuel. If pressure builds up after a couple of pulls on the recoil starter, squeeze the gun trigger to relieve it. Check that the choke lever is correctly positioned – move it to the "Choke" position when starting, or to the "No Choke" position if the engine is already hot or has been exposed to heat. Also, make sure the spark plug wire is securely attached and the engine switch is in the ON position.

  If you're experiencing no or low pressure with your Simpson Pressure Washer upon initial use, there are several things to check. First, ensure the spray wand is set to high pressure. The water supply must be at least 5 gpm @ 20 PSI. Inspect for any leaks at the high-pressure hose fitting and repair them, using sealant tape if needed. Also, check for obstructions in the nozzle and clean it if necessary. Finally, examine the water filter screen for clogs and clean it following the proper procedure.

  If your Simpson Pressure Washer isn't drawing chemicals, make sure the spray wand is set to low pressure. Check the chemical filter for clogs and clean it if necessary. Ensure the end of the detergent siphon hose is fully submerged in the cleaning solution. If the chemical is too thick, dilute it to a water-like consistency.

  If you notice oil leaking at the pump of your Simpson Pressure Washer, several factors could be the cause.

Also, inspect the vent plug for clogs and clean it, or replace it if the problem persists. Finally, check the air filter for oil saturation, and clean or replace the filter element.
