    Three years ago, after having two poor experiences with Karcher pressure washers, I was persuaded by their customer services department to buy another one. This time I bought the top of the range K5 ecology.
    Bad mistake! three years later its dead! Karcher have no local repair facilities and advise that I have to take it to an independent repair company in Liverpool or Warrington. As I live approx 12 miles from Chester, this would mean two trip of about 3 -4 hours in total and 120 miles and then they require £25 before they will even look at it. I am told that in fact it will probably be cheaper to buy a new model.
    Whats wrong with Karcher? My experience of them is that they now produce cheap throw away short term products that can even creep below the worst Chinese standards. This time, I will NOT be buying another “not so” cheap and nasty Karcher

    • David Whitehead

      All that generally goes wrong with them in my experience and is very easy and cheap to fix; the washers wear out. The clue is in the name ‘pressure washer’. Everything is under pressure. The washers only cost a few quid from Espares, change them and away you go! I also keep my pressure washer indoors during the winter months to prevent the water inside freezing. I have had my K5 for eight years. You don’t throw your car away when the tyres wear out do you?

      • Ian Gillespie

        They aren’t any better I’ve had a E145 which has died just outside of warranty.

        I’m back to Karcher as at least the K5 Premium has a 5 year warranty

    • john fearon

      Just bought the Karcer K5 Premium full Control Plus went to wash my car after purchasing a karcer foam cleaner but couldn’t get the foam through the gun as the cleaner wasn’t releasing phoned karcher and they said I need another fitting that attaches to the bottle and the lance…another £31.99 lighter after spending £389 buying direct …
      Wouldnt buy off them again been very poor ….

    I bought two other steam cleaners which lasted no time at all – I have now gone back to buying a Karcher model and I couldn’t be happier. They are the best steam cleaners available and beat all the upright models hands down.

    Mine was delivered yesterday so today I thought I would wash the car with it, assembled it all and began, behind me water was pissing out from behind the drum flooding my garage!

  4. Valerie Smith

    IM on my own,and need advice about the k5, as I’ve a large patio,I’ve had an much older,model for 20 years its just gave up,Now if i bought the K5 and it didn’t work how would i get it Repaired B&q,after taking your money will not take it back,so any advice please.Val

  5. David Whitehead

    You have a right under the new consumer act to reject faulty goods in the first 28 days. So take it back and if they won’t give you your money back ask the bank to charge back your credit or Visa Debit Card.

    I purchased a Karcher K5 full control from local Homebase store (May 2018) to replace an older Karcher machine which had given up the ghost. After assembly I discovered it wasn’t working properly. LCD display kept defaulting to the “detergent setting” with subsequent loss of pressure. I contacted Karcher customer services (30 minute wait to get answered). I was told that the unit needed primed and was emailed instructions on how to do this. I argued on the phone that this wasn’t the issue suspecting a software fault. I was then advised to return unit to retailer for replacement. I did this and Homebase replaced it without any issue (surprise surprise!!). I took the replacement machine home and before opening the box did a bit of on line research re assembley, user issues etc. I subsequently discovered that the model being sold at Homebase was obsolete and had been superceded by the “Premium” full control. Why? No idea. Anyway, I returned the unboxed Karcher to Homebase for a full refund and I bought a Nilfisk washer on line. So to cut a long story short … don’t waste your time on Karcher go straight for a Nilfisk a different beast altogether. Re the Karcher … an LCD display and battery operated wireless control … on a powerwasher ?….I ask myself how long is that going to last for!!!

    • Ian Gillespie

      Don’t think that Nilfisk are more reliable. I’ve got an E145 that has died just out of it’s 2 year warranty and Karcher before that lasted 6 years!

      K5 Premium now as it has a 5 year warranty

  9. TheBatman

    Is it possible to use the pressure washer with an aftermarket gun as opposed to the one powered by batteries?
