  If your Simpson Pressure Washer isn't drawing chemicals, check these potential causes: * Ensure the spray wand is set to low pressure. * Clean the chemical filter if it's clogged. * Make sure the end of the detergent siphon hose is fully submerged in the cleaning solution. * Dilute the chemical if it's too thick; it should have the same consistency as water. * Lengthen the water supply hose instead of using a long high-pressure hose.

Why won't my Simpson ALH3225 Pressure Washer engine start?

  Your Simpson Pressure Washer engine might not start due to several reasons. First, ensure you have fresh fuel. Second, if pressure builds up after a couple of pulls, squeeze the gun trigger to relieve it. Also, check that the choke lever is in the correct position (move to the "Choke" position if it is in the "No Choke" position, or move to the "No Choke" position if it is in the "Choke" position on a hot engine). Verify the spark plug wire is attached and that the engine switch is in the ON position.

  If your Simpson Pressure Washer has no or low pressure upon initial use, check several things. Ensure your water supply is at least 5 gpm @ 20 PSI. Repair any leaks at the high-pressure hose fitting, applying sealant tape if needed. Make sure the choke is in the “No Choke” position. Also, disconnect the water source from the pump inlet and turn the water source on to remove all air from the hose. When there is a steady stream of water present, turn water source off. Re-connect water source to pump inlet and turn on water source. Squeeze trigger to remove remaining air. Finally, confirm that the high-pressure hose is under 100 feet (30 m).
