Hello Andres777

Thank you for taking the time to share you experience with us. It sounds as though your nozzles may be clogged or there is some air trapped in the unit, these are common issues. With the following troubleshooting, this should be resolved! Please be sure to follow closely as these steps are not as effective when altered.
1) To clean the nozzles, soak all your nozzles in a half and half mixture of warm water and white vinegar. Soak all the nozzles for about an hour and then proceed to poke your nozzle cleaning tool or paper clip through the end of the nozzle hole to poke out any debris. After you have done this, rinse them with warm water. Your nozzles will now be free of any obstructions causing the unit to malfunction.
2) Purge any excess air from the pump. Set up the unit as per usual and ensure you are not using an extension cord. Remove any nozzle that may be connected at the end of the wand. Make sure that you have a green light on the GFCI on the power cord. Turn your garden hose on but leave the pressure washer turned OFF. With the pressure washer turned off, squeeze on the trigger for about 3 minutes – allowing the water to run through the unit at no pressure. In doing so, you are bleeding the unit out of any air that may be stuck in the pump. After 3 minutes, turn the unit on. If it is running, reinstall one of your clean nozzles and continue using the unit.
3) Ensure that the water source is fully opened and is at least 60PSI.
4) There should be 10' of unrestricted garden hose between the hose connection and the unit, any kinks will prevent the flow of water going into the unit and prevent proper pressure. If you are still having trouble, please contact Greenworks at 1-888-909-6757 (1-888-90WORKS) or start a live chat on our webpage

Hello taysmth,

Happy to hear you are enjoying the product! Happy to hear you are enjoying the product! We would love to offer some tips to help care for the pressure washer.
When storing your pressure washer over the winter or for longer than 30 days, make sure it will be ready for your next cleaning project. Your manual will have specifics. Here are some general procedures:

• Store the pressure washer in a dry area, protected from freezing temperatures and other extreme weather.
• Keep it away from heat sources that could dry out the pump seals.
• Use a pump lubricant/antifreeze. A pump protector is liquid Anti-Freeze formulated to prolong the life of your pressure washer; the product can be found at most hardware stores. If you cannot do the Optimum Winterizing procedure, you can still protect your pressure washer from winter damage by disconnecting all water connections. Turn on the machine for a few second, until the remaining water in the pump exits. Turn off immediately.
• Do not allow high-pressure hose to become kinked.
• Store the machine and accessories in a room that does not reach freezing temperatures.

If the pressure washer is subjected to freezing temperatures or is to be stored or left unused for ANY period longer than thirty days, the unit should be stored properly. This is called “winterizing”. The term is somewhat confusing because your storage period may or may not happen in cold temperatures or even during winter. Nevertheless, this procedure is strongly recommended to be done every time the unit may sit for longer than thirty days without being used. Whether stored inside or out, heated space or cold, winter or summer. This keeps the unit from freezing and, very importantly, it keeps water from drying out inside the pump and leaving behind very harmful deposits. These deposits will act like sandpaper in the seals the next time it is used. This also keeps any parts from rusting or oxidizing which may destroy your pump.

If it ends up that you are having an issue with the pressure washer, please contact Customer Support at 1-888-909-6757 (1-888-90WORKS), and we would be happy to assist you further in remedying an issues. Thank you for the 5-star review!
