Why won't my Stihl Pressure Washer start?
- D
  Daniel MorrowAug 18, 2025
  If your Stihl pressure washer doesn't start, even when the spray gun trigger is pressed, several issues could be the cause. First, ensure the connecting cord or extension cord is properly plugged in. Check the circuit-breaker (fuse) or earth-leakage circuit breaker, resolving any electrical overloads or defects, and switch off other electrical consumers on the same circuit. The fuse rating of the socket might be too low, so use a socket with the correct rating. Confirm that the extension cord has the correct cross-section and length. Finally, the electric motor may be too warm; let the pressure washer cool down for 5 minutes and clean the nozzle.

  Your Stihl pressure washer might not start even when the trigger is pressed due to several reasons: * The connecting cord or extension cord might not be properly plugged in; ensure they are securely connected. * A tripped circuit-breaker or earth-leakage circuit breaker may be the cause. Reset the breaker and reduce the electrical load on the circuit. * The socket's fuse rating may be too low; use a socket with the correct rating. * An incorrect cross-section or excessive length of the extension cord can also prevent starting; use an extension cord with the correct specifications. * The motor may be too warm; allow it to cool for 5 minutes and clean the nozzle.

Also, switch off other devices connected to the same circuit. * Using an extension cord with an incorrect cross-section. Ensure you are using an extension cord with an adequate cross-section. * The extension cord being too long. Use an extension cord of the correct length.

Why does the pressure fluctuate on my Stihl RE 150 PLUS Pressure Washer?
- N
  nharveyAug 26, 2025
  If the working pressure of your Stihl pressure washer fluctuates or drops, it could be due to several reasons. First, check for a water shortage by fully opening the water tap and ensuring a sufficient water supply. A blocked nozzle can also cause this issue, so clean it thoroughly. Additionally, inspect the water intake screen and water filter for blockages and clean them if necessary. If these steps don't resolve the problem, the high-pressure pump, high-pressure hose, or spray attachment may be leaking or defective, and you should have a STIHL servicing dealer check the pressure washer.

Why is my Stihl RE 150 PLUS Pressure Washer not drawing detergent?
- E
  Eric NelsonAug 27, 2025
  If your Stihl pressure washer is not drawing in additional detergent, the detergent container might be empty, so fill it with detergent. Also, the fan jet nozzle might not be turned in the correct direction, so turn it fully. If neither of these steps works, the Venturi nozzle might be worn, and you should have the tool repaired by a STIHL servicing dealer.

  If your Stihl pressure washer shuts off while you're using it, there are a couple of things to check: * Make sure the plug of the connecting cord or extension cord is fully inserted into the socket. * The circuit-breaker or earth-leakage circuit breaker may have tripped. Find and resolve the cause, then re-engage the breaker. Also, try switching off other electrical devices on the same circuit to prevent overloading.

  If the high-pressure pump of your Stihl pressure washer switches on and off repeatedly without the trigger being pressed, it indicates a leak in the system. The high-pressure pump, high-pressure hose, or spray attachment may be leaking. In this case, you should ask a STIHL servicing dealer to check the pressure washer.
