Troubleshooting a Stihl Pressure Washer Not Working
If your Stihl pressure washer is not working, there are a few things you can check to troubleshoot the problem.
1. Check the power supply:
Make sure that the pressure washer is plugged in and that the power switch is turned on.
2. Check the water supply:
Make sure that there is water in the pressure washer’s reservoir and that the water supply is turned on.
3. Check the air filter:
The air filter can become clogged with dirt and debris, which can prevent the pressure washer from starting. To check the air filter, remove it from the pressure washer and clean it with a brush or compressed air.
4. Check the fuel filter:
The fuel filter can also become clogged with dirt and debris, which can prevent the pressure washer from starting. To check the fuel filter, remove it from the pressure washer and clean it with a brush or compressed air.

The spark plug can become fouled or damaged, which can prevent the pressure washer from starting. To check the spark plug, remove it from the pressure washer and inspect it for damage. If the spark plug is fouled, clean it with a spark plug cleaner or replace it with a new one.
6. Check the fuel pump:
The fuel pump can fail, which can prevent the pressure washer from starting. To check the fuel pump, turn on the pressure washer and listen for the fuel pump to prime. If you don’t hear the fuel pump priming, the fuel pump may be faulty and will need to be replaced.
7. Check the engine:
If the pressure washer still won’t start after checking all of the above, the problem may be with the engine itself. To check the engine, you will need to take the pressure washer to a qualified repair shop.
