Karcher 3300 G water leak out rear of unit from white plasticplug

I have a karcher 3300G water is leaking badly out of a white plug in the rear of the unit. Looks like a simple plug that was inserted with an allen key (large one) well should be a rather cheap and easy fix right?
Karcher tech support is non existant and their service dealer network wont help anyone with parts only if I wanted to bring it in for top cost. Im not sure Karcher even has a tech support department. Obviously I wont be buying anything from Karcher again but in the mean time I got this power washer leaking badly any thoughts?

    Ok Im with you being a pool owner. But if you look at the plug itself not sure what it is its part of an elaborate kind of pressure device its two pieces seperated by two O rings. Im sure its the O rings from my paintball days they tend to give out rather quickly. Buts its so goofy they way they designed it. I dont think the plug has threads it seems to plug into another piece seperated by an O ring.

  • megabyte29 Jun 20, 2009

    Yeah it seems the plastic piece is part of a 2nd piece some kind of weak engineered pressure blowup device. Badly designed as to fail on purpose or why so many small pieces seperated by O rings. I checked on the Karcher parts to re place it they only make an entire pressure plastic kit it costs $70 whoa are they that dumb? Thats 1/3 the cost of the unit for just 10 plastic parts. To buy that specific part no bigger than a dime weighing about .1 ounce it costs $2 with $7 shipping. Doing the research on this unit Karcher doesnt support it at their website and from all the bad postings of this company they have no tech support not even a phone number to get information only a phone number to sell you parts that you cannot get information about so how can you order the parts you need when they dont provide any schmatics or help diagnosing the problem. Karcher claims that their service network is top notch and they deal with all phone and service issues. Problem is nobody told their service dealers about the phone tech support because those that are still in business dont give phone tech support they will only repair the unit under warranty. Karcher never bothered to update their service dealer network as the 10 I called in a 30 mile radius only one was still in business and he told me flat out he hates Karcher and thinks anyone who buys their products is just the stupidest person in the whole world then hung up the phone on me? Of course since Karcher has no phone to complain to your left with the feeling Karcher wants your money but they dont plan on supporting you one bit after the sale. Call the number 1-800-537-4129 its halarious all the buttons refer you to a dead recording of non existant divisions like online only tech support you go to the website the tech support takes you email then never answers it. But the phone line is quick to tell you how to purchase MISSING PARTS whoa whats this? It seems Karcher ships products missing parts who ever heard of such a thing. I have read many many internet postings of horror stories of customers buying products then not getting all that was advertised on the box. Its seems prior customers are removing the parts they need to complete or fix their Karcher items that break right out of the box like mine. So my suggestion is if you need a part go back to the store where you got it and purchase another unit remove the parts you need and return it. Karcher can go to hell as far as im concerned and of course I will do everything in my power to have them go out of business as soon as possible to save the american consumer of this german company sticking it to the stupid american buyers who dont check out the company prior to a purchase! WISE UP DONT BUY FROM KARCHER!

If its just a plug, remove it with an allen key and wrap a couple layers of teflon tape around it. That should stop, or at least slow down any leaks that are coming out of the threads.

Why is smoke coming from karcher pressure washer and leaking from underneath

You need to make sure you have water flowing through the machine before you turn it on. The pump could be bad in it and or the seal make have broken which is causing the Ayer o leak out.

Karcher dirtblaster leaking at the end

If it's leaking it obviously has a bad seal or is broken. I would try to disassemble and see if it has a seal or not. Sounds like you could have a bad "O" Ring or some other type of seal leaking but I'd bet on an "0" Ring damaged or wore out. Dissemble it and see what is sealing it and proceed accordingly.

Leaks water - not sure where it comes from. Thank

Coffee leaking into the drip tray could be from the brew unit or the front door assembly. Water leaking probably means a hose connection to the boiler has failed. Don't just leave it, fix leaks immediately. Besides the electrical danger, the rust on working parts from long term leaks can be extensive.

Are you confident? Operate the machine with all covers off to see where the leak comes from. Be extremely careful, ready to pull the plug at any moment. Touch nothing inside! Burning, scalding and electrified! Check both boilers very closely while making coffee, most leaks become obvious on close examination.

Most leaks are due to failed o-rings in the connectors at the end of the teflon hoses, usually at the coffee boiler. Replacing the o-rings should stop the leak.

Source replacement o-rings. Slide the hairpin c-clip out of the side of the white connector and pull the teflon hose out. Fish the old o-ring out of the connector with a small hook or point if it didn't come out with the hose. Place the new o-ring over the end of the hose, snug against the brass collar. push the hose back into the coupling being careful to go straight and true so as not to damage the new o-ring. Some force may be required, be careful not to kink the hose. Blunt needle nose pliers to push the rear of the brass collar usually does it. Replace the c-clip and test for further leaks before reassembling.

Hi My karcher k3.65 jubilee is leaking water when the pump is switched off from underneath

Hi This could be just the water inlet channel broken or split. You will need to remove the yellow cover via the screws at the back of the unit and then connect the water hose to see where the leak is coming from. If the water comes from underneath the pump then you will need a replacement pump seal kit of which you can purchase on the Internet.

I have a Karcher KB5050 it started to pulse when the trigger stopped

Is there water leaking from the bottom ? If so, then you have a leak in the pump. Bad seal or crack in the Pump.
If under 1 year old and have a receipt, Call Karcher for a warranty replacement.

Pressure washer that leaks oil through the air breather

Most likely your air filter is plugged or dirty, or the crank case vent valve needs to be cleaned.if it still does it check that the oil level is at the full mark, if overfilled it would cause the same problem.
