Twice I have experienced water leaks from the hose connector. The first time, I was advised by the approved repairer that it was caused by the way I used the machine ! Yet even being aware of the potential of a leak at the hose connector and never pulling on the hose the machine has developed the same leak.
I experienced a malfunction of the trigger handle and the same repairer, here on the Gold Coast, advised me it was again caused by the way I used the machine ! What a small "O" ring in the handle failure was caused by my incorrect use of th...Read more

Got a K3 part number 1.601 - 812.0. Assembled the unit; connect all hoses and turned on water. Immediately started leaking from the k3 quick coupling connector to hose and from the trigger gun (the lance seems to work fine tough, at least I saw no leaks from there) - I rechecked connections as I wasn't believing there was an issue so serious as this product is from a good reputation brand like karcher... Well I ran out of options... My unit has assembling issues.. There's a defect on the quick coupler to hose (connects k3 to rubber hose) and al...Read more

I had a wonderful Karcher that lasted many years, when it died I decided to replace it with another Karcher thinking Id get the same service life, unfortunately it lasted 11 months and started to leak oil, I took it to the service repair shop as it was under warrantee and after they checked it all out they advised Karcher would replace it with a K3 as it was not worth fixing. My replacement K3 is just over 2 years old now and has developed a severe leak and vibration so its on its way out. I always thought Karcher were a good brand but if you a...Read more

After my old Karcher packed it in after about 10 years,I thought I'd replace it with a new one instead of being repaired.Big mistake.
I purchased a K3 from bunnings brought it home assemble it and started using it,lasted about 5 minutes before you could hear a loud water hissing sound from inside it a water pouring out of the vents,so I returned it to bunnings for a replacement same model.Got home again plugged the new one in and started using it and again may have got 5 minutes usage then the same thing as the first one something has given wa...Read more

I'm an independent contractor to constructor builders (housing), I've been through 4xK2, 1xWinner 11 and 2xK3, in 24 months. I only use them on windows and decking only. They get used, on average, once a week. I operate them in short periods of time, as recommend by Kärcher themselves.

The K2's fall apart after two to three uses. The Winner 11 is my older, personal pressure cleaner. When the fitting from the pump to the hose blew out, I went to the Geebung store, seeking a new part. When I was handed the replacement part, it was to narrow,...Read more

I bought a Karcher K3.190 pressure washer from Bunnings 2.5 years ago. I have used it about 7 times to wash cars and deck. It started gushing water and lost pressure. I returned it to Bunnings and they sent it off for repairs. It is outside the 2 year warranty and they quoted $150 to repair. The unit cost me $289 so I decided against it. The repairer told me the fault is a cracked water pump. He said they are made of plastic at a price point and that this was a common fault. I bought a Karcher because I thought I was getting a quality brand but...Read more

Purchased this K3 pressure washer brand new after my old metal Karcher had lasted for nearly twenty years. So decided to stick with the brand. Worked well for a while - maybe four hours of use at the most. Was quite impressed. Then yesterday it started spewing water out of the base of the housing and the pressure at the nozzle dropped by about 60%. Took it back to Bunnings this morning and was told that, as I had no receipt, there was nothing they could do. So, stuck with a $299.00 door stop. If you are seriously going to buy one of these Ch...Read more

Our Gerni broke so off to Bunnings we went to get a new one. Given our history with Gerni we decided to try Karcher. We opted for the Karcher k3-800 ecologic. Big mistake. After about half a dozen short uses he pressure washer let go and more water came out the bottom than the top. The Bunnings receipt had faded to nothing, and since we paid cash there was no bank record. Bunnings pointed me at Karcher. I sent them an email, nothing. I rang and was told the sales manager (Mike) would ring me back. Still nothing after a month. The product has a ...Read more

Purchased from Supercheap while there was a storewide sale for $240~. It comes with some wood deck detergent, a line spraying wand (with power adjustment), dirt blaster wand (main one I use) and a water broom. It doesn't come with a 'patio cleaner' extension - but not a big deal as I've found them to be useless in the past.

I have been using it to clean dirty and moldy concrete (and works fine).

I've had a Bosch 37-13+ previously but it burnt out after 1 day of use. I've also used a JetPower JET360ZX. Both of these are similar to th...Read more

I recently purchased a Karcher K3 Deck pressure cleaner from Home Hardware in Launceston. Their price was $239 down from $299 quoted to match Bunnings price for a similar model.
I bought this to clean some rather old stained concrete, paving stones and a deck and it has done a reasonably good job of it.
I have had a basic model cheap Gernie for many years which has been great but has just worn out from a lot of use so needed to replace.
Three reasons I opted for the Karcher this time were a long pressure hose, adjustable spray nozzle and...Read more
