Why Karcher Pressure Washer Motor Not Working
Why
No power
The most common reason for a pressure washer motor not working is that it is not getting power. This can be caused by a number of things, including:
A blown fuse
A tripped circuit breaker
A loose or damaged power cord
A faulty switch
To troubleshoot this issue, first check the power cord to make sure it is plugged in securely and that there are no visible signs of damage. If the power cord is okay, check the fuse box or circuit breaker panel to make sure that the correct fuse is in place and that it is not blown. If the fuse is blown, replace it with a new one that is the same amperage as the old one. If the fuse blows again after you replace it, there may be a problem with the wiring in your home. You should contact an electrician to have this checked out.
Clogged water inlet
Another common reason for a pressure washer motor not working is a clogged water inlet. This can prevent water from flowing to the pump, which will cause the motor to overheat and shut down. To troubleshoot this issue, first disconnect the water hose from the pressure washer and check the inlet screen for any debris. If the screen is clogged, clean it with a brush or a piece of wire. If the screen is not clogged, check the water supply to make sure that it is turned on and that there is no obstruction in the line.
Faulty pump
If the water inlet is clear and the pressure washer is still not working, the problem may be with the pump itself. The pump can fail for a number of reasons, including:
Worn out seals
A broken impeller
A faulty motor
To troubleshoot this issue, you will need to remove the pump from the pressure washer and inspect it for any damage. If you see any damage, you will need to replace the pump. If you do not see any damage, you can try cleaning the pump with a brush or a piece of wire. If the pump still does not work after cleaning it, you will need to replace it.
Other possible causes
In addition to the reasons listed above, there are a number of other possible causes for a pressure washer motor not working. These include:
A faulty switch
A bad connection between the pump and the motor
A problem with the pressure regulator
A problem with the hose
A problem with the gun
If you have checked all of the possible causes listed above and the pressure washer still does not work, you should contact a qualified technician for help.
