Karcher Pressure Washers

Description

Leaky pressure washer?

The usual suspect is one of the elbow connections, especially if your water pressure is also poor. Due to bad weather or lack of use these connectors can split over time. Replace it to help stop leaks and get cleaning with full power again. 

Please note: Does not include the o-ring seal, which can be purchased separately here.

This spare is chassis and serial number dependent for certain models. Please contact our Call Centre with these details so we can check if it's suitable for your machine. Your chassis number should look like: 1.504-604.1, and the serial number is 6 digits long.

    The new parts fitted perfectly. The clip to fasten the unit was very tight but a small drop of oil did the job. Can recomend buying spareparts here

  • Q still have leak in replaced outlet connection 3 Answers

    model 4.99 new out elbow fitted. leaking at point where elbow meets outlet pump. Ordered o ring for it. I have fitted it over the screw fit on the outlet pump. now cannot fit new elbow to pump. cannot insert metwl clamp. Any ideas? Am I puting the o ring in the correct place? Any help appreciated Bob

      As stated above you need a small O ring which doesn't come with espares part (although espares claim it comes woth all seals). I found that when I connected up to the low pressure hose the outlet connection leaked slightly so I wasn't hopeful. However when I switched on the pump the leak got worse for a second then it stopped suddenly - I assume the pressure seated the O ring properly. The sealing method is quite confusing - the outlet connection has an internal tube with an external O ring which looks like it should seal to the inner surface of the pump outlet. However it as actually much too small to do this - presumably it's for use with a different model. Incidently the pressure hose will seal directly to the pump outlet (without using the elbow) and it seals using this type of external O ring. It seems Karchner use some universal parts that seal in different ways on different models.

      Hi Bob, You need the small 'O' ring which is about the same size as the one on a male garden hose connector. It just sits on the inner pipe. The screw fitting is not actually used with this connector and (I think) was or is for a different machine using the same pump. The big orange DIY store does a pack of 'O' rings in the plumbing section for about £1.99. The one you need is in there - so is the larger one for the Inlet (clear plastic) pipe. That one sits in a groove and is easy to see! Best of luck, CJ

      The O ring fits inside the female connection of the pump so that it buts up to the elbow outlet fitting.

  • Q O-ring needed or not ??? 2 Answers

    After replacing this part, anytime I hook up the pressure hose, the pressure forces water out through the other end i.e. metal c-clip end (washer is still off). Is there a seal/o-ring that I am missing at this end ?

      Nearly made the same mistake. Inside there is a small rubber O ring, luckily I saw it when it fell out but could easily have missed it.

      Yes. It is a standard size, Though I cannot remeber the actual size.

  • Q our washer keeps running out of water 1 Answer

    there is plenty water pressure at the inlet (3.5bar) can i increase the jet on the float valve at the tank ?

      If the water level is dropping on your machine it is either leaking underneath or perhaps more likely it is syphoning down the drain hose. This can occur if the end of the drain hose is lower than the water level in the machine. To cure this fix the drain hose with the 'crook' to not allow the end to be lower, for more details see our video: http://www.espares.co.uk/advice/7/1732/how-to-diagnose-washing-machine-drain-and-pump-problems

  • Q Pressure Washer Outlet Connector leaks when I turn on the pump 1 Answer

    hi i have just fitted a new pressure washer oulet connector, fitted quite easily, but when i switch on the pump it leaks, but when i turn the pump off and allow the water to flow through it doesnt leak, o ring is in place too, any suggestions please

      Hi mark, it may well be that the pump itself has become damaged or cracked - especially if the symptoms started since you started using your washer again after the winter months. Water freezing inside the pump can cause damage and leaks.
