I have a Karcher 550M pressure washer and was using today when all of a sudden the water started to pour through the handle hence lost the pressure of the water. Is this a rubber washer issue or the gun needs replacing or simpler than that. To be honest although I have had the washer for about 3/4 years now It is hardly used. Also can I fix it and where would I purchase the allen key to replace. Thanks Brian

The pump seems to build up the pressure because when I release the handle the pump motor stops. This is a fairly new pump which was purchased in the latter part of last year(2010). Could this have been caused by the detergent I have been using which is an automotive shampoo? Please help I love this washer and for the times that I u

Hi, I have a Karcher K3 pressure washer. 18 months old, used maybe 6 hours total.
