How to Troubleshoot And Fix: Pressure Washer Motor Not Working

Check Power Supply

First and foremost
ensure that the pressure washer is plugged into a working power outlet. It may seem obvious
but a loose connection or a tripped circuit breaker could be the culprit behind the motor not working.

Inspect the Power Cord

Take a close look at the power cord for any signs of damage such as fraying or cuts. A damaged power cord can prevent the motor from receiving the necessary power to operate effectively.

Examine the On/Off Switch

The on/off switch is a critical component of the pressure washer motor. Make sure it is in the on position and functioning properly. If the switch is faulty
it may need to be replaced to restore motor functionality.

Check for Overheating

Overheating can cause the pressure washer motor to shut down. If the motor feels excessively hot to the touch
allow it to cool down before attempting to use it again. Additionally
ensure that the air vents are not blocked
as this can lead to overheating.

Inspect the Capacitor

The capacitor is responsible for starting the motor. If the capacitor is defective
the motor may not start. A multimeter can be used to test the capacitor for continuity. If it is found to be faulty
it should be replaced.

Examine the Pressure Switch

The pressure switch plays a crucial role in regulating the motor’s operation. If the pressure switch is malfunctioning
it can prevent the motor from running. Check the pressure switch for any signs of damage or wear and tear.

Test the Motor Brushes

The motor brushes transmit electrical current to the motor’s commutator. Over time
these brushes can wear down
leading to motor failure. Inspect the brushes for wear and replace them if necessary.

Inspect the Thermal Release Valve

The thermal release valve is designed to release water and pressure from the pump when the water inside the pump becomes too hot. If the valve is stuck open
it can prevent the motor from starting. Ensure that the thermal release valve is functioning correctly.


In conclusion
troubleshooting and fixing a pressure washer motor that is not working can be a straightforward process when following
