How To Repair Dewalt Pressure Washer
If your Dewalt pressure washer is not working properly, it can be frustrating and time-consuming to try and figure out what the problem is. However, with the right knowledge and a little bit of patience, you can easily diagnose and repair most common issues with your pressure washer. In this article, we will discuss some common problems you may encounter with your Dewalt pressure washer and provide step-by-step instructions on how to troubleshoot and fix them.
Step 1: Determine the problem
The first step in repairing your Dewalt pressure washer is to determine exactly what the problem is. Is the engine not starting? Is the water pressure too low? Is the machine leaking? By identifying the specific issue, you can narrow down the potential causes and solutions. This will save you time and ensure that you are addressing the correct problem.
Step 2: Check for clogged nozzle or spray gun
One common issue with pressure washers is clogged nozzles or spray guns. This can cause a decrease in water pressure or even a complete loss of pressure. To check for a clogged nozzle, remove it from the spray gun and inspect it for any debris or dirt. If it appears dirty, clean it thoroughly with water and a small brush. If the nozzle is damaged or worn out, you may need to replace it.
Step 3: Inspect the hoses and fittings
Another common issue with pressure washers is leaks in the hoses or fittings. Inspect all the hoses and fittings for any visible signs of damage, such as cracks or tears. If you find any leaks, you will need to replace the damaged hose or fitting. It is also a good idea to check that all the fittings are tightly secured, as loose fittings can cause leaks.
Step 4: Check the engine
If your Dewalt pressure washer is powered by an engine, it is important to check that the engine is running properly. Make sure that the spark plug is clean and in good condition. Check the air filter and clean or replace it if necessary. If the engine still does not start, you may need to consult the manufacturer’s instructions or contact a professional for further assistance.
By following these steps and troubleshooting the common problems with your Dewalt pressure washer, you can save yourself time and money by repairing it yourself. However, if you are not comfortable performing these repairs or if the problem persists, it is recommended to seek the help of a professional technician.
Troubleshooting Dewalt Pressure Washer Problems
Having a reliable pressure washer is essential for maintaining the cleanliness of your outdoor surfaces. However, like any mechanical device, Dewalt pressure washers can encounter problems from time to time. In this troubleshooting guide, we will address common issues that may arise and provide possible solutions to help you get your pressure washer back up and running.
Low Pressure
If your Dewalt pressure washer is not performing at its full potential and has low pressure, there could be several causes. First, check the water supply to ensure there is enough water flowing into the machine. If the water supply is adequate, inspect the inlet filter or screen for any clogs or debris that may be blocking water flow. Additionally, check the nozzle for any blockages and clean it thoroughly if necessary. If none of these fixes solve the issue, consider checking the pressure regulator or contacting a professional for further assistance.
Leaks
Leaks are another common problem with pressure washers. If you notice water leaking from the pump, check the seals and connections for any damage or wear. Tighten any loose connections and replace any damaged seals or o-rings. If the leak persists, it may be necessary to replace the pump. For leaks in the hose, inspect the connections for any damage or wear and tighten them if needed. If the hose itself is damaged, consider replacing it with a new one.
Leaks can also occur at the wand or spray gun. Inspect the connections and seals for any damage or wear. Tighten any loose connections and replace any damaged seals or o-rings. If the leaks continue, it may be necessary to replace the wand or spray gun.
No Start or Motor Issues
If your Dewalt pressure washer won’t start or is experiencing motor issues, begin by checking the power supply. Ensure that the power cord is properly plugged in and that the outlet is functioning correctly. If the power supply is not the issue, check the on/off switch for any damage or wear. If the switch is faulty, it may need to be replaced. Additionally, inspect the motor for any loose or damaged connections. If the motor is not working properly, it may require professional repair or replacement.
These are just a few of the common problems that can arise with Dewalt pressure washers. By troubleshooting and addressing these issues, you can prolong the life of your pressure washer and ensure that it continues to perform at its best.
| Problem | Cause | Solution |
|---|---|---|
| Low Pressure | Insufficient water supply or clogged filter/nozzle | Check water supply, clean filter/nozzle |
| Leaks | Damage or wear in seals, connections, or hose | Tighten connections, replace damaged parts |
| No Start or Motor Issues | Faulty power supply or on/off switch, loose/damaged motor connections | Check power supply, replace switch, repair/replace motor |
Common Issues
1. Low Pressure
If your Dewalt pressure washer is experiencing low pressure, there are several possible causes. First, check the water supply. Make sure the water source is fully turned on and that there are no kinks or obstructions in the hose. Next, inspect the nozzle and spray gun for any blockages or clogs. Clean them if necessary. Additionally, check the pump for any damage or leaks that could be affecting the pressure.
2. No Pressure
If your pressure washer is not producing any pressure at all, there may be a problem with the pump. Check the pump inlet and outlet valves to ensure they are functioning properly. If they are clogged or damaged, they may need to be cleaned or replaced. You should also inspect the pump seals and O-rings for any signs of wear or damage. Replace them if necessary.
3. Leaking Water
If water is leaking from your Dewalt pressure washer, it could be due to a faulty hose or connection. Inspect the hose for any cracks or holes, and replace it if necessary. Check all connections and fittings to ensure they are tight and secure. If the pump is leaking, it may need to be repaired or replaced.
4. Engine Issues
If the engine on your pressure washer is not starting or running properly, there are a few things you can check. First, make sure the fuel tank is filled with clean, fresh gasoline. Check the spark plug for any signs of wear or damage, and replace it if necessary. If the engine still won’t start, there may be a problem with the carburetor or ignition system that requires professional repair.
5. Abrasive Damage
If your pressure washer is not working as effectively as it used to, it could be due to abrasive damage. Over time, the water pump and other components can become worn from using abrasive cleaning solutions or running the pressure washer without water. To prevent this damage, always use the appropriate cleaning solutions and ensure the water supply is connected before starting the pressure washer.
Tools and Materials Needed
Before you start repairing your Dewalt pressure washer, you will need the following tools and materials:
- Safety goggles: It is important to protect your eyes when working with a pressure washer to avoid any potential injuries.

- Replacement parts: Depending on the specific problem you are facing, you may need to have replacement parts on hand, such as hoses, nozzles, or valves.
- Pressure washer lubricant: Lubricating the internal components of the pressure washer can help improve its performance and prolong its lifespan.
- Clean cloth: Use a clean cloth to wipe away any dirt or debris from the pressure washer.
- Waterproof tape: If you have any leaks in the hoses or connections, waterproof tape can help seal them temporarily until you can replace the damaged parts.
By gathering these tools and materials before starting your repair, you will be prepared for any issues that may arise, and you will have a smoother and more successful repair process.

Preventive Maintenance Tips
Regular preventive maintenance can help extend the lifespan of your Dewalt pressure washer and prevent costly repairs. Here are some tips to keep your pressure washer running smoothly:
