What to do if my Stihl RE 163 Pressure Washer has no supply of detergents?

  If your Stihl Pressure Washer is not supplying detergent, there are a few possible reasons. First, check if the detergent tank is empty and fill it if necessary. If the tank isn't empty, the detergent intake may be clogged, so try to eliminate the clog. If neither of these solutions works, the Venturi nozzle may be worn, and you should have the machine checked by a servicing dealer.

  If the engine of your Stihl Pressure Washer stops, it may be because the motor is overheating. Check to ensure that the supply voltage and machine voltage match. Allow the motor to cool down for at least 5 minutes before restarting.

Why does the pressure fluctuate or drop on my Stihl RE 163?

  If the pressure of your Stihl Pressure Washer fluctuates or drops, it could be due to several reasons. First, ensure that the water supply is sufficient by fully opening the water tap and complying with the permissible suction lift if you are using suction mode. Another cause may be a dirty high-pressure nozzle, which you should clean. Also, inspect and clean the water intake strainer, as it may be clogged. If these steps don't resolve the issue, the high-pressure pump may be leaky, or the valves may be defective, or the nozzle is clogged. In these cases, have the machine checked by a servicing dealer.

How to fix a Stihl Pressure Washer when the motor hums but doesn't run?

  Jennifer HillAug 27, 2025
  If the motor of your Stihl Pressure Washer does not run when switched on but hums, it could be due to several reasons. First, check the electrical connection, plug, cable, and switch. The mains voltage might be too low or improper. If you're using an extension cord, it might have the wrong cross-section; use one with a sufficient cross-section. Also, an extension cord that is too long can cause this issue, so connect the machine without an extension cord or with a shorter one. Another possibility is that the mains circuit-breaker has been tripped. To resolve this, switch off the machine, actuate the spray gun until water only drips out of the head, engage the safety catch, and then reset the mains circuit-breaker. Finally, make sure to actuate the spray gun when switching on the machine.
