Karcher pressure washer loses pressure...

Posted by sammybar on January 26, 2009, 6:57 pm

Hi all,

My Karcher pressure washer loses pressure very quick. As a result when
standby the motor restart the operation constantly for a few seconds.
When operating the washer is fine and the pressure OK.
A guy said it is a matter of a "seal" that needs replacement. He said
it is an easy task. I have been googling for a while but it is no
information on Karcher web site on repairing or servicing its
machines.
Does anybody did such a repairing? Any indications, hints available
online? Any part catalog for Karcher is available online?

Any hint is welcomed
Thanks in advance
Sammy

This is how a Karcher tells you that the pump is getting ready to
fail. If you have more than 5 or 10 hours on it, it's about done. Kiss
it goodbye.

There are many seals on it, find the leak then you will know if its
worth fixing. A friend used his Karcher every week for maybe 10 yrs
only the switch broke even, mine is 4 yrs old, used maybe 8-20 hrs a
year and its fine. I have heard they got cheap recently, if its under
warranty have them fix it. Look for drips it should not leak.

I repaired a Karcher washer not long ago. Had a hell of a time trying to
find parts; finally ended up getting them from a little bitty place
waaaay up in Pinole (anyone familiar with the San Francisco Bay Area
will know how out of the way that is) that sold and serviced small gas
engines.

The Karcher site does have very good documentation for their washers,
including exploded diagrams that make it pretty easy to locate the
parts. I think the part I had to replace was a seal.

Made From Pears: Pretty good chance that the product is at least
mostly pears.
Made With Pears: Pretty good chance that pears will be detectable in
the product.
Contains Pears: One pear seed per multiple tons of product.

David,
I have been looking around the Karcher web sites but all the
documentation I can find is the user manual. Exploded diagrams will be
very helpful for me but I can not locate where they are. Could you
point me to the right place?

Thanks you very much for your hint
Sammy
