What to do if my Simpson Brute Pressure Washer electric motor does not start?
- J
  James AllenAug 25, 2025
  If the electric motor on your Simpson Pressure Washer doesn't start, check the following: * Ensure there's electric power by checking the cord, plug, socket, and breaker. * See if the thermal overload in the motor or starter has tripped; reset it after the motor cools. Be cautious of automatic overloads that restart the motor automatically. * Inspect the power switch. * Address any electric motor or wiring failures by repairing or replacing the affected components. * Confirm adequate water pressure at the inlet by connecting to an appropriate water supply.

How to fix a Simpson Brute engine that cranks but won't start?
- J
  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 does my Simpson Brute Pressure Washer pump run but have no spray pressure?

  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.

Why isn't my Simpson Pressure Washer downstream injector siphoning chemical?
- M

  If the downstream injector on your Simpson Pressure Washer isn't siphoning chemical, consider these issues: * The adjustable knob on the injector might be closed (if applicable); open it by turning counterclockwise. * The unit might not be in low-pressure mode; open the dual wand or install a low-pressure (BLACK) nozzle. * The detergent hose could be cut or kinked; inspect and replace it if needed. * The chemical strainer might be plugged or not submerged; check the screen on the strainer pickup tube. * Internal injector parts could be corroded or stuck; disassemble and clean or replace them. * The outlet water temperature might be too high; use cold water (150ºF maximum).

  If the pilot light is on but the burner won't fire on your Simpson Pressure Washer, check for 24 VAC between the main valve (MV) and PV/MV. If there's no VAC at the valve, replace the module. If you get voltage, replace the valve.

What causes the discharge water temperature to exceed the recommended temperature on my Simpson Brute?
- M
  marcjohnsonSep 7, 2025
  If the discharge water temperature on your Simpson Pressure Washer exceeds the recommended operating temperature, it could be due to: * Burner input being too high for the conditions: Decrease fuel pump pressure and/or fuel nozzle size. * Restricted water flow: Clean or replace the nozzle with the proper size, descale the coil, and clear any obstructions. * A faulty high-temperature limit switch or one set too high: Replace or reset the temperature limit switch.
