1. Simpson Pressure Washer Engine won’t start

There could be several reasons why your engine won’t start. Follow these steps to troubleshoot:

  • Fuel level: Make sure there is enough fuel in the tank. If the tank is empty, fill it with fresh gasoline. Check the fuel line for any leaks or kinks that may prevent fuel from reaching the carburetor.
  • Oil level: Check the oil level and add oil if necessary. Running the engine without enough oil can cause serious damage to the engine.

  • Air filter: The air filter is an important component that prevents dirt and debris from entering the engine. Make sure the air filter is clean and properly installed. If the filter is dirty, replace it.

  • Spark plug: The spark plug starts the engine. Check the spark plug for any signs of damage, such as cracks, corrosion, or fouling. If the spark plug is damaged, replace it.

  • Choke lever position: The choke lever controls the amount of air and fuel that enter the engine. Make sure the choke lever is in the correct starting position. If the choke lever is in the wrong position, the engine may not start.

2. Pressure washer won’t build pressure

If your pressure washer isn’t building pressure, it could be due to any of the following. To troubleshoot, follow these steps;

  • Inlet water filter: The inlet water filter prevents dirt and debris from entering the pump. Check the inlet water filter and clean or replace it if it’s clogged.

  • Inlet water supply: Ensure sure there is adequate water flow to the pressure washer. Check the water source for any kinks or clogs in the hose, and make sure the hose is properly connected.

  • Nozzle: The nozzle controls the flow and pressure of the water. Inspect the nozzle and make sure it’s not clogged. If the nozzle is clogged, clean it with a needle or replace it if it’s damaged.

  • High-pressure hose: The high-pressure hose carries water from the pump to the nozzle. Inspect the high-pressure hose for any kinks or clogs that may reduce water flow. If there are any issues with the hose, replace it.

  • Unloader valve: The unloader valve regulates the pressure in the pump. Check the unloader valve and make sure it’s functioning properly. If the unloader valve is not functioning properly, replace it.

3. Simpson Pressure Washer Engine overheats

If your engine is overheating, there could be many reasons for this. The steps below will guide you on how to troubleshoot:

  • Cooling system: Check the cooling system and make sure it’s functioning properly. Ensure there is enough water flowing through the engine, and check the radiator for any signs of blockage.

  • Air filter: A dirty air filter can reduce airflow to the engine, causing it to overheat. Inspect the air filter and replace it if it’s dirty.

  • Engine oil: Check the engine oil level and make sure it’s at the correct level. Running the engine with low oil can cause overheating.

  • Spark plug: A fouled or damaged spark plug can reduce engine performance and cause overheating. Take a look at the spark plug and replace it if it’s fouled or damaged.

4. Simpson Pressure Washer Leaks

Leaking issues on the Simpson washer could be due to several reasons. Below are steps to resolving such issues.  

  • Hoses: Check all hoses for any signs of damage or leaks. Replace any damaged hoses.

  • Connections: Look though all connections and make sure they’re tight and secure.

  • Pump head: The pump head can develop leaks over time. Take a look at the pump head for any signs of damage or leaks, and replace the pump head if necessary.

5. Simpson Pressure Washer Vibration Problems

Vibration problems with a pressure washer tend to be common and could be the result of the following issues

  • Loose components: Check for any loose components on the pressure washer and tighten any loose bolts or screws.

  • Uneven pressure distribution: If the pressure is not evenly distributed, it can cause the pressure washer to vibrate. Check the pressure distribution and adjust the pressure as needed.

  • Worn-out pump: A worn-out pump can cause the pressure washer to vibrate. Check the pump for any signs of wear or damage and have it repaired or replaced if necessary.

  • Worn-out engine mounts: If the engine mounts are worn out, it can cause the pressure washer to vibrate. Take a look at the engine mounts and replace any that are worn out.

6. Simpson Pressure Washer Poor Cleaning Performance

Performance issues are due to several factors. Some could be due to your usage, others could be caused by the pressure washer. Here are some steps to troubleshoot poor cleaning performance:

  • Low water pressure: Check the water pressure and make sure it’s within the recommended range for your pressure washer. If the water pressure is too low, the cleaning performance will suffer.

  • Dirty nozzle: A clogged nozzle can reduce the cleaning performance of your pressure washer. Inspect the nozzle and clean it or have it replaced.

  • Incorrect nozzle: Using the wrong nozzle can affect the cleaning performance of your pressure washer. Take a look at the nozzle and make sure it’s the correct one for the task you’re performing.

  • Dirty or clogged pump: A dirty or clogged pump can reduce the cleaning performance of your pressure washer. Look through the pump and clean or replace it if needed.
