Having problems with your Karcher Pressure Washer Gun 91120200 91120200 ?

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

Won start Was using the pressure washer 1st time this year and started on the second pull. Ran out of gas shut-off also noticed it needed oil.

This time the resistant was there on the pull but still would not start; no attempt even to turn over.

My Karcher K3.48M pressure washer remains in the low pressure mode even when I return the pressure nozzle to the high pressure position. How can this be corrected. 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

I have the Coleman powermate 2400 PSI pressure washer and on initial start it sprays and has great pressure. But once I release the spray handle it will not spray again, not even one drop of water. I have verified water pressure, bought 3/4 hose, and also changed the spray handle with no help.

... Pressure Washers

I have had 3 Karcher pressure washers all experience the same problem and so have two of my neighbors. Our area has very hard water and it causes problems with the washer not bringing up the pressure when the trigger is pulled (or surges up and down) and the nozzles clogging, etc. The service repair facilities cannot tell me how to prevent this. Many attempts to contact Karcher for advice have been ignored. I have been thinking that perhaps running the engine for a few seconds with no hoses a
