Why won't my Simpson Pressure Washer engine start?
- L
  Lance MannJul 28, 2025
  Your Simpson Pressure Washer engine might not start due to several reasons. The fuel tank could be empty, so add fresh fuel. The spark plug wire might be detached; connect it properly. The engine switch might be in the OFF position; turn it to the ON position. The engine fuel could be turned off; turn the fuel on. Also, check if the engine oil is low and fill it as per the engine manual, as a low oil sensor might shut off the engine. Water pressure in the pump might be preventing the engine from turning over; aim the spray gun in a safe direction and pull the trigger to release water pressure in the pump. Finally, the engine choke might be in the wrong position, refer to the STARTING ENGINE section of this manual for the correct choke position.

What to do if my Simpson MS61222 has low or no water spray pressure?

  If your Simpson Pressure Washer has low or no water spray pressure, consider these potential causes: There might be air in the hoses and/or pump. In this case, refer to the PRIMING THE PUMP section of this manual to remove air from pump and hoses. The water supply might be insufficient; ensure the water supply pressure is at least 5 gpm @ 20 PSI. The nozzle or water inlet screen could be clogged; clean them according to the MAINTENANCE section of this manual. The high-pressure hose might be too long; ensure it is less than 100 feet long.
