    Why does my Simpson Brute Pressure Washer pump run but have no spray pressure?
    • P
      pamwileyAug 27, 2025
      If your Simpson Pressure Washer pump runs but there's no spray pressure, consider these possible causes: * The water supply might be off; turn it on. * The nozzle could be plugged; clean or replace it with the proper size. * The inlet chemical injection valve might be open without the pickup tube in detergent; close the soap valve or submerge the detergent pickup tube in the solution (upstream injection systems only). * The coil on hot water machines could be obstructed; clean any obstructions or scale deposits with a coil cleaner. * The pump might be dry and needs priming; crack open the fitting on the high-pressure outlet until water flows out.

    How to fix a Simpson Brute engine that cranks but won't start?

      Jennifer WrightAug 26, 2025
      If your Simpson Pressure Washer engine cranks but won't start, the issue could be due to several reasons: * The engine power switch might be off or defective, so check it. * The low oil shut down may be activated; add oil to the engine and check the oil level more frequently. * The unit may be low on fuel; fill it with the correct fuel and bleed the injector pump if it's a diesel engine. * The fuel filter could be clogged; replace or clean it, and bleed the injector pump if it's a diesel engine. * The engine might be flooded or starved; use the choke only as needed (not applicable to diesel engines). * The fuel could be old or dirty; drain and replace it with fresh fuel.

    Why won't my Simpson Brute Pressure Washer engine start or crank over?

      Christine McconnellAug 22, 2025
      If your Simpson Pressure Washer's engine won't start or crank over, possible causes include a dead battery (charge or replace it, adding electrolyte if new), dirty battery contacts (clean them), disconnected battery cables (connect or replace), a seized engine, pump, or gearbox (identify, replace, or repair the seized part), a defective key switch, solenoid, or starter (repair or replace), or a seized pump (replace the pump or bearing).
