Why won't my Kärcher K 3.000 motor start?

L
Lauren WolfSep 8, 2025
Your Kärcher Pressure Washer motor might not start because the On/Off switch is in the “OFF” (0) position. Turn the switch to the “ON” (I) position. Also, check if the power cord is properly plugged in and that the electrical outlet supplies adequate power. Try a different outlet. Another potential cause is a tripped GFCI plug; if so, press the “RESET” button on the GFCI plug. Finally, a tripped internal circuit breaker can also prevent the motor from starting. If this is the case, switch off the pressure washer; the reset will occur automatically once the unit's temperature drops.
