Pressure Washer Pump Repair Guides & Tips


Pressure washer pump has become the most advantageous tool nowadays.

Whether it is home, office or industrial area, we can see the use of this handy stuff rapidly growing.

My point is, sometimes we need to repair our old pressure washer pump to make it working again at full performance.

A pressure washer pump repair guide may help the user to know the specific way to repair it. And I am going to show you some information about repairing your pump those will guide you. Let’s move our eyes on the whole article.

Usually, you can replace the whole pump or any damaged part to start your lobby or garden cleaning again. It would take on average to replace the pump. You may repair by removing 3 or 4 bolts of the pump most of the times.

Never think that replacement of the pump will reduce the service. I can say you may get the exact service which you got from the old one. Before replacing or repairing the pump you have to keep few things in mind.




The very first thing is to check that the warranty of the pressure washer pump is valid till now or not. Many pumps provide up to 4-year product warranty. So, it will be better if your pump has the warranty. Now, if you are going to use the warranty benefit, check that you are valid to get the warranty service as per as their conditions of warranty.

You get your pump repaired from them. Again, some pump seller doesn’t have a physical location to repair your pump. But they will provide necessary assistance, providing repairman. Call them on their phone number or email them (especially for online dealing). Many pumps have a return policy if they are bought within 30 or 60 days ago.

That means if you find any error in the pump within 30 or 60 days, you can claim new pump from the seller.


Find Reason to Fail to Work

Secondly, check the reason your pump is failing to work as usual. Possibly most of the pump face two issues those create problem to work flawlessly.
The first issue is a problem with the water source. Dirty water or insufficient water going through the machine can damage the pump.

The second issue is pump’s oil level.

  • For the first issue, you need to turn off your pump first.Then I would suggest checking the filter screens
    (generally intake valve is closed near filter screens).These filters may be clogged with dirt, silt, leave, etc., which can hinder the water flow.Even your pump can be burnt due to this.So, make sure these filter screens are clear.If not, clean them as soon as you start the machine again.
  • For the second issue, always try to check the pump oil level.If the oil level is low, your pump will stop while you are using it.Fill the pump oil according to manual.



Decision Between Repair and Replacement

Thirdly, the decision between repair and replacement of the pump is quite important. If you are using a wobble pump, then unluckily there is no chance to repair the pump. You will need to replace the whole car pressure washer.

Wobble pumps are economically but not designed to repair them. So, change the entire washer without thinking. If your pump is an axial cam pump, then you have the option to change the damaged parts or repair them or replace the pump. Repairing may take less than 2 hours. Even you can repair the pump by yourself if you have the knowledge and the parts.

If you’re knowledgeable on using a plasma cutter, it’ll help you to cut any type of metal during repairing the pump.

You can order the parts online and get them in your home or office. While ordering them, you need to check the model and specs of your pump and buy the appropriate parts. Take a wrench and unbolt the damaged pump from the machine. Then check the problematic parts and replace or repair them.

Many pressure washer pump manufacturers sell replacement pump, pump kit and repair tools for the customers who are facing problems with the pump alongside the product warranty.

Annovi Reverberi, Karcher, Briggs & Stratton, Homelite, Generac, APW Distributing etc. company offer these products online.
