When an electric pressure washer won't start, there could be various reasons behind the issue. Here are some troubleshooting steps you can follow to try and fix the problem:
Check the power source: Ensure that the pressure washer is correctly plugged into a working electrical outlet. Verify that the outlet is providing power by testing it with another device. If the outlet is not functioning, try connecting the washer to a different outlet.
Inspect the power cord: Examine the power cord for any visible damage, such as cuts or fraying. A damaged power cord may prevent the pressure washer from receiving power. If you find any damage, replace the power cord with a new one from the manufacturer or an authorized dealer.
Reset the GFCI: Many electric pressure washers come with a Ground Fault Circuit Interrupter (GFCI) on their power cord. If the GFCI has been tripped due to a power surge or other issues, it will cut off power to the washer. Press the reset button on the GFCI to restore power.
Check the ON/OFF switch: Ensure that the ON/OFF switch on the pressure washer is in the correct position. Sometimes, the switch may become loose or malfunction, preventing the machine from starting.
Inspect the trigger gun and wand: Some pressure washers have a safety feature that prevents them from starting if the trigger gun is not engaged. Make sure the trigger gun is properly connected to the wand, and the wand is securely attached to the pressure washer. Squeeze the trigger while starting the machine.
Verify water supply: Electric pressure washers typically have a safety mechanism that requires a steady water supply to be connected before they can start. Check that the water supply is turned on and that there are no obstructions or kinks in the hose.
Check for clogs in the inlet filter: The pressure washer's inlet filter may get clogged with debris, restricting water flow and preventing the machine from starting. Clean the filter or replace it if necessary.
Inspect thermal overload protection: Some pressure washers have thermal overload protection that automatically shuts off the motor if it overheats. Allow the unit to cool down if it has been running continuously and wouldn't start.
If you have gone through these troubleshooting steps and the electric pressure washer still won't start, there might be a more significant issue with its motor or electrical components. In such cases, it's best to contact the manufacturer's customer support or a qualified service technician to diagnose and fix the problem. Attempting complex repairs without proper knowledge may void the warranty or lead to further damage.
