Greenworks Pressure Washer Not Working: Causes & Fixes

The Greenworks pressure washer is known to be a reliable tool, however, you might encounter basics while using it. One of the most basic problems is the Greenworks Pressure Washer not starting when it should.

In this guide, we will provide an in-depth look at the potential causes of a non-working Greenworks pressure washer, as well as the steps you can take to fix the problem.

Greenworks Pressure Washer Not Working: Causes & Fixes

1. No Water Pressure

One of the most common reasons for a pressure washer not working is a lack of water pressure. This can be caused by a number of factors, including:

  • A blocked hose: If the hose that supplies water to the pressure washer is blocked, the water flow will be restricted, resulting in low pressure.
  • A closed valve: If the valve that controls the flow of water to the pressure washer is closed, the pressure will be low.
  • A faulty pump: If the pump that pressurizes the water is not functioning properly, it can result in low pressure.

To fix this, you will need to identify the cause of the low water pressure and take the appropriate action. This may involve cleaning the hose, opening the valve, or replacing the pump.

2. Clogged Nozzle

Another common issue that can cause a pressure washer to stop working is a clogged nozzle. The nozzle is the small opening at the end of the wand that controls the flow of water and determines the pressure and spray pattern. If the nozzle becomes clogged with debris, it can restrict the water flow, resulting in low pressure or no pressure at all.

To fix this issue, you will need to remove the nozzle from the wand and clean it. You can do this by using a small wire or needle to carefully remove any debris that may be blocking the opening.

3. Clogged Filter

A clogged filter can also be the fault. The filter is a small screen located in the inlet hose or on the pump itself, and it is designed to prevent debris from entering the system. If the filter becomes clogged, it can restrict the water flow, resulting in low pressure or no pressure at all.

To fix this issue, you will need to locate the filter and clean or replace it as needed. Depending on the model of your pressure washer, the filter may be located in the inlet hose or on the pump itself. Consult your owner’s manual for more information on how to access and clean the filter.

4. Motor Not Working

If the motor on your pressure washer is not functioning properly, it can cause the unit to stop working. This can be caused by a variety of issues, including a faulty motor, a blown fuse, or a tripped circuit breaker.

To fix this issue, you will need to diagnose the problem and take the appropriate action. This may involve replacing the motor, replacing the fuse, or resetting the circuit breaker.

5. Worn-out Belt

One of the common issues is a worn-out belt. The belt is a flexible loop that connects the motor to the pump and is responsible for transferring power from the motor to the pump. If the belt becomes worn out or damaged, it can cause the pump to stop functioning properly, resulting in low pressure or no pressure at all.

To fix this issue, you will need to locate the belt and replace it with a new one. Depending on the model of your pressure washer, the belt may be located on the side of the motor or on the pump itself. Consult your owner’s manual for more information on how to access and replace the belt.

6. Leaking Hose

A leaking hose can also cause a Greenworks pressure washer to stop working properly. The hose is responsible for delivering water from the faucet to the pressure washer, and if it is leaking, it can cause the unit to lose pressure or shut off completely.

To fix this issue, you will need to locate the leak and repair or replace the hose as needed. If the leak is small and the hose is otherwise in good condition, you may be able to patch the leak with a hose repair kit. If the hose is badly damaged or the leak is too large to patch, you will need to replace the hose.

7. Faulty Gun

A faulty gun can is not very common but also possible. The gun is the handle that controls the flow of water and determines the pressure and spray pattern. If the gun is damaged or not functioning properly, it can cause the pressure washer to stop working or produce low pressure.

To fix this, you will need to replace the faulty gun with a new one. Depending on the model of your pressure washer, you may be able to purchase a replacement gun from Greenworks or a third-party supplier. Consult your owner’s manual or contact Greenworks customer service for more information on how to obtain and install a new gun.

8. Clogged Inlet Filter

The inlet filter is a small screen located in the inlet hose or on the pump itself, and it is designed to prevent debris from entering the system. If the filter becomes clogged, it can restrict the water flow, resulting in low or no pressure.

To fix this issue, you will need to locate the inlet filter and clean or replace it as needed. Depending on the model of your pressure washer, the inlet filter may be located in the inlet hose or on the pump itself. Consult your owner’s manual for more information on how to access and clean the inlet filter.

9. Worn-out Pump

Over time, the pump on a Greenworks pressure washer can become worn out or damaged, causing it to stop working properly. A worn-out pump can result in low pressure or no pressure at all.

To fix this, you will need to replace the worn-out pump with a new one. Depending on the model of your pressure washer, you may be able to purchase a replacement pump from Greenworks or a third-party supplier. Consult your owner’s manual or contact Greenworks customer service for more information on how to obtain and install a new pump.

10. Faulty Motor

If the motor on your Greenworks pressure washer is not functioning properly, it can cause the unit to stop working. This can be caused by a variety of issues, including a faulty motor, a blown fuse, or a tripped circuit breaker.

To fix this, you will need to diagnose the problem and take the appropriate action. This may involve replacing the motor, replacing the fuse, or resetting the circuit breaker. Suppose you cannot identify the problem or fix it on your own. In that case, it is recommended to seek the help of a professional or contact Greenworks customer service for assistance.
