Costco Husqvarna 3100 PSI Gas Pressure Washer

One of these days I’m going to get myself a pressure washer. I’ve always wanted one so I can post on reddit under Power Washing Porn. Trust me, it’s not a dirty site & after looking at some of the photos, you may just want one yourself. I was surprised to see the brand Husqvarna though. Costco usually carries Honda, GreenWorks or Yamaha. Husqvarna has a great reputation with their outdoor power tools, specifically chainsaws & this power washer is probably no different. Here are a few notes on this item……

  • Briggs & Stratton EXi875 190cc gas engine
  • 5 nozzles (0, 15, 25, 40 degrees & soap)
  • 30 foot high pressure hose
  • 2 year limited warranty
  • Ready start technology
  • No priming or choking
  • Regular gas. No mixing oil (See link below for the manual in PDF format)

You can clean your driveways or garage floors, decks, concrete & tile patios, stairs, walkways, fencing, cars, trucks, tools, lawn mowers, boats, trailers & anything that won’t come off with a wipe. Just be careful not to damage anything with the 3100 PSI.

  1. Purchased the husqvarna pw 3100 late last year. Just took it out of the box to use it yesterday. Set it up and attached hose, but no water would go through the machine. Blockage in pump? I could see no issues with the intake. So far no luck in finding a solution on line or a number to call to talk to a person.

    1. Does the machine turn on without issue? Are all the connections tightened? Any chance the O-rings fell out or are not creating a good seal. When I setup my pressure washer the first time I sprayed all the O-rings with WD-40 and made sure all the connections were tight. Do you happen to have the Low Pressure Spray tip installed? Is there a blockage in any of the hoses? Let me know if you end up solving the issue. I am curious

  2. Just bought a husqvarna pressure washer from Costco put it together , put gas and oil in, connected water, purged , followed all instruction. Doesn’t work. Won’t start , no spark. Taking it back.

    1. That’s the first I heard of the Husqvarna having an issue like that. Did you get another one or just gave up? I just purchased the Husqvarna Electric 2000PSI pressure washe. I have yet to unbox it, but I was specifically looking for electric & compact & this one fits the bill. Hoping it’s a quality tool.

    1. It is regular gas. No mixing oil which gets to be a real pain. Per the manual it is “Clean, fresh, unleaded fuel with a minimum of 87 octane. Gasoline with an ethanol content up to 10% is acceptable.”. I’ll post a link to the manual since it has been taken down from the Costco site

  3. I bought this at my local costco and put it together easy enough. Comes with a siphon hose and detergent bottle holder but no detergent bottle or instructions on how to use the detergent. I cant find anything online on how this is supposed to work and I cant figure it out.

    1. I checked the manual. This pressure washer comes with a siphon hose that attaches directly to pressure washer concentrate. I am not 100% sure but something like this on Amazon would probably work. You buy the concentrate in a bottle & attach the bottle directly to the siphon hose. The bottle obviously needs to be able to fit in the detergent holder. I hope that makes sense. Make sure to read the manual and use the correct spray tips when using the detergent. They apparently don’t mix and match well. Also, this item just went on sale. I’ll post the new price soon. It’s $80 off, so hopefully you can get a credit!

        1. Briggs & Stratton makes pressure washer cleaners for different types of cleaning….concrete & driveway, house & siding, multipurpose cleaner, spot free rinse aid & vehicle cleaner. Here is the link for the 32 oz bottles that should fit nicely in the Husqvarna pressure washer. I don’t know why Husqvarna created a “bottle holder” & did not supply an empty bottle or at least sell a detergent that fits nicely with their product. Seems like a missed oppurtunity for them to make a few extra bucks. Please let me know how it works out for you.
