We’ve received a few calls and e-mails from customers who are experiencing issue with getting their Snap-on electric pressure washer to start or stay running.  Here are some troubleshooting tips from the manufacturer:
If your pressure washer is plugged in but won’t run, try these steps:
1. Press the RESET button on the GFIC plug (you can do this while the unit is plugged in). This may be required before each start-up.
2. Make sure the ON/OFF switch is in the ON position
3. Note that motor only runs when you squeeze the trigger on the wand and shuts off when the trigger is released.
If your pressure washer keeps shutting off or surging while in use, try these steps:
1. If you are using an extension cord with the unit, trying operating it without the extension cord. Using an extension cord can trigger the thermal overload protector on the motor, shutting it off.
2. The household circuit you are plugging the unit into may be delivering less than 120V to the unit, which can trigger motor shutdown. Test this by changing the wand pressure setting to the lowest pressure output. If the unit runs normally in this mode, then you need to plug the unit into a dedicated 120V outlet. This is typically the outlet that a washer, dryer or fridge is plugged into.
3. The wand may be clogged with debris. Your pressure washer ships with a wire probe that can be used to clean the wand outlet, and your user manual includes instructions on how to properly clean the wand.
