Got the same washer as you, really good unit, has never failed me. Mine is red and I think I bought it in 98. When I have problems with the disconnect I put a little grease on it. If I forget to let off the pressure, it won't release. Mine has been abused and I use it a lot, don't think I've changed the oil in the motor more than a couple of times. Just changed the oil in the pump this year. I take very good care of my autos, mower, quad, etc, but for some reason I overlook my washer.
