How to fix the pressure washer pump for the most common causes of pressure washer pump failure?
1. Overheating the pump
One of the most common causes of pressure washer pump failure is overheating. When the pump overheats, the oil breaks down and can no longer lubricate the moving parts. This will cause the pump to seize up and fail.
There are a few things that can cause the pump to overheat:
- Running the pump for too long without giving it a break
- Using the wrong oil in the pump
- Blocking the pump's cooling fins
- Not enough water flowing through the pump
If your pump is overheating, turn it off and let it cool down for a few minutes. Then, check the oil level and ensure it is filled to the correct level. If the oil looks dirty, replace it with new oil.
If the pump is still overheating, ensure nothing is blocking the cooling fins. If there is, clean it off and try again.
Contact a pressure washer service center for help if you still have problems.
2. Running the pump dry
Another common cause of pressure washer pump failure is running the pump dry. This can happen if the pump is not getting enough water.
There are a few things that can cause the pump to run dry:
- The inlet screen is blocked

How do you check a pressure washer pump?
If you own or use a pressure washer, it's essential to know how to check the pump. The pump is responsible for delivering water under high pressure to the nozzle, so the pressure washer will be less effective if it isn't working properly. There are a few different ways to check a pressure washer pump, and the best method will depend on your pump type.
If you have a diaphragm pump, the most common type of pressure washer pump, you can check it by removing the inlet screen and looking for debris. If there is debris in the pump, it can restrict water flow and cause the pump to overheat. You can also check the diaphragm pump by removing the cover and looking for leaks. If you see any leaks, you'll need to replace the seals.
If you have a piston pump, you can check it by looking for leaks around the seals. If you see any leaks, you'll need to replace the seals. You can also check the piston pump by removing the cover and looking for damage to the piston or cylinder. Again, you'll need to replace the pump if you see any damage.
If you have a gear pump, you can check it by removing the cover and looking for damage to the gears. If you see any damage, you'll need to replace the pump.
Once you've checked the pump, check the pressure washer hoses for leaks. Leaks in the hoses can also cause the pump to overheat and fail. If you find any leaks, repair them before using the pressure washer again.
Is a pressure washer pump protector necessary?
It depends on what you're using your pressure washer for. If you're primarily using it for home cleaning projects, then a pump protector probably isn't necessary. However, a pump protector is recommended if you're using your pressure washer for more heavy-duty tasks like cleaning concrete or removing rust.
A pump protector helps protect the pump from potential damage caused by excessive heat or particles in the water. It's a good idea to have one installed if you're using your pressure washer for tougher jobs, as it can help prolong the life of your pump.
What are some tips for prolonging the life of your pressure washer pump?
If you own a pressure washer, you know how important it is to keep the pump in good working condition. After all, the pump is what makes the pressure washer work. Without a well-functioning pump, your pressure washer will be pretty useless.
Fortunately, there are some things you can do to prolong the life of your pressure washer pump. Following these simple tips can keep your pump running strong for many years.
1. Use filtered water in your pressure washer.
If you use unfiltered water in your pressure washer, the pump will eventually become clogged with sediment and other debris. This can cause the pump to wear out prematurely. To avoid this problem, always use filtered water in your pressure washer.
2. Don't run the pump dry.
If you run the pump dry, meaning there is no water running through it, then the pump will overheat and could be damaged. Therefore, always ensure there is water running through the pump when using your pressure washer.
3. Use a pressure washer pump saver.
A pressure washer pump saver is a device that attaches to the end of your hose and prevents the water from back-flowing into the pump. This can help prolong the life of your pump by preventing it from being damaged by backflow.
4. Winterize your pressure washer.
If you live in an area that gets cold in the winter, you'll need to winterize your pressure washer. This involves adding a special solution to the pump to prevent it from freezing.
5. Store your pressure washer in a cool, dry place.
If you store your pressure washer in a hot, humid place, the pump can become damaged. Always store your pressure washer in a cool, dry place.
6. Don't use your pressure washer for applications it wasn't designed for.
Some people make the mistake of using their pressure washers for applications they weren't designed for, such as power washing their car or cleaning their deck. Unfortunately, this can damage the pump and void your warranty. Instead, use your pressure washer only for the applications it was designed for.
7. Have your pressure washer serviced regularly.
Like any other machinery, your pressure washer needs to be serviced regularly. This involves having a technician inspect the pump and ensure it functions correctly.
By following these simple tips, you can prolong the life of your pressure washer pump and keep it running strong for many years to come.
