If you're having pressure washer pump problems, and thinking about pump repair or replacement, this page is for you. I share my pro advice on the most common troubleshooting solutions and when to repair - or replace.
You can check out my top axial pump recommendation: the Generac Universal Pump on Amazon.
And you can see my #1 Honda pressure washer replacement pump recommendation: the Homelite Universal 3,000 PSI pump on Amazon.
This Homelite is a high quality replacement axial cam pump for Honda pressure washers with a maximum 3,000 PSI - and it's priced right. It's a maintenance-free unit because the oil is pre-filled and permanently sealed in the pump. This Homelite pump is rated for 300+ hard working hours! I highly recommend this axial pump.
You can check Amazon's pricing on the Homelite Universal 3,000 PSI pump.
Eventually, all pressure washer pumps will fail or wear out. But, before you try to repair or replace it, read these quick troubleshooting tips, first, to try to save yourself time & money.
And if you need a triplex replacement pump on your Honda pressure washer, I highly recommend this Triplex Pump on Amazon. It's built tough with ceramic plungers, that will resist pitting & wear, with a forged brass manifold for durability. This Triplex pump will give you a max pressure of 3,000 PSI and 3.1 GPM. And it comes with a thermal relief valve, easy start valve & pressure relief valve!
Warranty: I know it seems obvious, but do think you might still be covered under the manufacturers warranty? Each pump manufacturer has a different warranty period - anywhere from 30 days to 2 years.
A quick look at your owners manual will tell you. But, if your owners manual isn't handy, you can call the 800 service number that's listed on the 2-3" silver name plate, near your engine. And it has your washers serial number. It never hurts to call and double check your warranty.
Less Water Flow? I can't tell you how many damaged pumps I've seen just because the washer is drawing in dirty or insufficient water. And it's only because the filters screens, especially near the intake valve, are dirty. And it will eventually burn up a pump. Take a moment to see if your filters are clogged with grit, dirt or leaves.
Also, a leaking hose, valve, o-ring or leaking gun will drop your water pressure and flow. These parts are very cheap & easy to replace and it's a quick fix.
No Water Flow? First - immediately turn off your unit! Without water flowing through your pressure washer, your pump will quickly fail. Then check to make sure your garden hose isn't kinked.
If this is the first time you've tried to start your pressure washer after storing it in the winter, you need to change the oil right away! The old oil will keep your pump from working properly.
Always check the oil level in your pump, using your dipstick or sight window. Always keep the proper oil level but never overfill it.

Quick Review of the Best Replacement Pumps
If you have a gas pressure washer and only need a slight repair or pump replacement, you're better off doing it yourself - rather than buying a whole new unit.
There are dozens of websites that have a wide selection of pressure washer parts and accessories at very competitive prices.
Most good gas pressure washers are priced between $300 -- $700+, but you can pick up a brand new, high quality replacement pump for about a $100. (See below). Pressure washer pumps are incredibly easy to install - usually just a matter of removing 3-4 bolts!
Here's My Top Recommendation for the Best Electric Pressure Washer:
I highly recommend the AR Blue Clean AR383 as the best electric pressure washer for any homeowner! Here's why I think it's the best electric unit:
It provides 1900 PSI which gives you very good cleaning power & speed - and it has an Annovi Reverberi Triplex 3 axial piston pump! As a pro, I know very well that the quality of your pump is critical for good cleaning results, consistent performance & long life. This Annovi Triplex pump is a much higher quality & longer lasting pump than you'll see on other electric washers. And you can read other customer reviews on Amazon.com.
And I know you'll really appreciate that this AR Blue Clean has a hose reel! Finally - you can get a hose reel on an electric unit! Trust me, the fact that you can neatly & quickly store your 20ft hose on the unit will help you work faster & more safely. And it's also easier to store. You can check this item at Amazons price.
