Brand new first-time use, I used it to suds my bike on low pressure and then a low setting for a rinse, didn't want to blast the bike and electrics with lots of pressure. When I was done with that I went to clean my deck and got nothing from it, totally dead. I wish I had of checked this board before wasting my time and money, off to Bunnings for a refund in the morning.

Terrible build quality. I have only used it a few times, wash deck/paving/car etc, washed my house down today. Keeps splitting pump housing bits. Cheap plastic, bad design, it only seems to last until barely out of warranty, which is also short. Total waste of money.

Worked fine for a bout 6 times then suddenly sprung a leak internally which i was advised by the retailer that it isnt repairable,this is my 3rd K3,all had the same issue...back to the retailer again to get it replaced.

The K3 split the pump casing as Karcher's do apparently (I wish I had read the reviews before purchase). It lasted a total of less than 20 hours of use over the few years I owned it which was unfortunately for me greater than their warranty period).

I bought SO many attachments and didn’t even get to use them as the Plastic pump housing with the 3 metal springs and rods MELTED the PLASTIC and TINY rubber seal in one of the 3 chambers. Will never buy Karcher again. So much for German quality. It’s a disgrace to my German heritage. I got so little use out of it.

I haven't had the issues other people seem to have had here. Unit seems reasonable quality to me but I don't use it that heavily.i just use it to clean the tiles on my patio every now and again

Only niggle is the plastic tube used to feed the detergent came off after the first use and I was unable to reattach.

Other than that this seems reasonable quality to me

Like most others have said - had it two years, pump housing split causing water to leak everywhere and loss of pressure - made from rubbish, cheap and nasty. Many people who have had Karchers previously swore by them - that must have been when Companies made things to last....

I have 2 kartcher pressure washers and both failed after little use with the same fault. A crack in the plastic housing of the pump. I have written a request to Karcher asking if it is a common fault and they don't reply.
Do yourself a favour dont buy Kartcher

Absolutely love this product. Effectively removes stubborn dirt from our concreted areas that was difficult to remove by hose and broom. Extremely easy to assemble and operate. Highly recommended product and great value for money.

The machine is just under 4 years old but with only occasional use. The pump housing has split in half at the joint so it's now going in the bin. Don't waste your money on this over priced rubbish.

Bought this from bunnings to wash my car, used it once and it worked so sweet as. Waited a week and went to wash my car again and its not building any pressure at all, like running on then off but pump is working at full max (water is dribbling out). Was turning the on switch and it just popped out, such cheap plastic junk, you should see the inisde, looks like its made out of chuppa chup sticks.
Now doesnt work at all (wont turn on or pump at all), so its going back to bunnings,, i wish i had read the reviews on here first.
thanks karcher for making absolute rubbish

I had bought that from bunnings for $289. It is used very sparingly - once in 1-3 months and may have used that for 15 times only and now it have all sort of problems. Water is leaking and it is not building pressure - sort of stop start. Unfortunately i had lost the receipt and bunnings said they can’t do anything. So all the money is lost/ wasted.

Bought at Bunnings for $300. Used about 5 times in 5 months then it gave up the ghost....no water pressure. But good news it has a 2 year warranty....but when I took it to Karcher to be repaired they told me that because I bought it on a Bunnings Powerpass card...I only get 3 months warranty. They considered me a professional user. Beware People! Piece of junk and terrible customer service.

This is my second Kärcher and both have died just outside of warranty. Both have had the same fault with the pump leaking causing the unit to loose pressure. Both machines had very little use and we’re not worth repairing considering the exorbitant service and parts cost.
I am bitterly disappointed as I thought I was purchasing a quality German made product however I now realise these items are manufactured in China.

Purchased K3 from Bunnings - lasted about 5 minutes before you could hear the water hissing out from behind the cover. Did read some of the warranty and decided not to try and fix it, so returned it too Bunnings for a replacement. All good about it, that's where the "all good" bit ends. The replacement started hissing out water as soon as I connected the water to it. Total waste of time and money. Would not have another one. (This was a replacement for a Worx cheapie that had lasted 10 years. The only reason I gave it away was I wanted a longer pressure hose. Wish now I hadn't given the old one away). Got the replacement on Friday, but have not returned it yet, now Sunday.

In the 3 years I've had it the unit has has failed 3 times and has been repaired by a local repair agent. It's now failed completely and is dead. Probably done about 10 hrs work in it's life.
Bunning were not at all interested once it had left the shop. Karcher are similarly disinterested unless you are a lottery winner. They stand behind their shareholders and not their product.

Not a wise decision - look elasewhere

I had my K-3 for about 2 and bit Years and the cover on top of the pump went.Tried to to get the part off Karcher and they were going to charge me more than what the machine was worth.
I tried to get it repaired and all the Karcher service centres around Cairns laughed at me and said it's not worth fixing as it will cost.
I will not buy a karcher Pressure Washer again.

Was good for 2 years of regular use and then the pump seals failed spraying water all inside the machine. This could be an electricity hazard when this happens. Also my dirt blaster nozzle stopped rotating. You can now get more powerful machines for significantly less cost so it is behind the times a bit in terms of pressure output. I'm not a fan of the plastic pump inside the machine and this is in my opinion why I think it failed.

Bought a K3 and the motor would not work properly and had no pressure, took it back to the shop and got a replacement unit. New unit worked but the lances had leaks and eventually after a few weeks of use the dirt blaster lance decided to stop working due to the ball bearing inside the nozzle tip eating it's way around the plastic housing causing it to stop rotating.
Looked at buying a new dirt blaster nozzle, $60 for a piece of plastic junk that will fail again, No way.
Decided to throw it off a building from the 3rd level, I got my satisfaction out of it that way, as well as a good video and a lesson learnt.
