Why won't my Simpson Pressure Washer engine start?

  Your Simpson Pressure Washer engine might not start due to several reasons. It could be because there's no fuel, so add fresh fuel. Check if pressure builds up after a couple of pulls; if so, squeeze the gun trigger to relieve pressure. Ensure the choke lever is in the 'Choke' position when starting a cold engine, or in the 'No Choke' position if the engine is hot or has been exposed to heat. Also, make sure the spark plug wire is attached and the engine switch is in the ON position.

What to do if my Simpson MS31025HT-S has no or low pressure?

  If your Simpson Pressure Washer has no or low pressure, several factors could be the cause. First, ensure the spray wand is set to high pressure. Make sure your water supply provides at least 5 gpm at 20 PSI. Check for leaks at the high-pressure hose fitting and repair them, applying sealant tape if needed. Clear any obstructions from the nozzle. Clean the water filter screen. Remove any air from the hose by disconnecting the water source, turning it on to flush air, and then reconnecting it, finally, ensure the choke is in the 'No Choke' position and that the high-pressure hose is under 100 feet.

What to do if my Simpson Pressure Washer won't draw chemicals?

  If your Simpson Pressure Washer isn't drawing chemicals, make sure the spray wand is in the low-pressure setting. Check and clean the chemical filter if it's clogged. Ensure the chemical screen is fully submerged in the cleaning solution. If the chemical is too thick, dilute it to the consistency of water. Use a longer water supply hose instead of a long high-pressure hose.
