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 washer was bought new at Lowes, but did not use for first three years of ownership, should have tested it. Thanks for any help on this. Ted Miller

I immediately shut it down and let it cool down. After it was cool, I turned on the water supply again and the relief valve was still spewing water from it.

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.

Also can I fix it and where would I purchase the allen key to replace. Thanks Brian

I have an older Landa Pressure Washer. The burner is not working. Once I get the machine running and water flowing to the pressure washer, with the wand pressed, I flip the burner on switch....and nothing...I have no idea how to work on a pressure washer burner. I have been told it could be the igniter, but I don't know how to fix it if it is. Any help is appreciated.

Troy-Bilt 2550 20293 pressure washer not producing pressure. Worked when last used 2 months ago. Pump pistons are moving up and down when engine is pulled through. Inlet water is flowing through pump but no pressure when engine is started. I have the same problem. Water flows thru the pump when not running, but no flow or goes in by-pass mode when I start the pump. The pump being Troy Bilt Model 020296-01. I replaced unloader valve even. Anything else I can do?

You replaced the unloaded valve. Are you positive you have the unloader screwed to pressure and not turned the opposite way? You will have no pressure if it is adjusted wrong. One other thing I have encountered is that the unloader has a ball bearing ... Pressure Washers

I have a McCulloch FH160B power washer and it no longer builds up pressure. I haven't used this very much at all. I tore it apart and cleaned everything I could find. When i pull the trigger for the spray nozzle, I get line water pressure. When I release the trigger, the power washer sounds like it starts to build up pressure. When this was working correctly, the pump would shut off when the trigger was released. Any suggestions?

Hi. I have a Briggs & Stratton 2800PSI gas pressure washer. I can get it to start, but after about 5 min, then it quits. I have cleaned the carb, change oil, changed plug, new gas, cleaned/checked air filter. Nothing will keep it running.

Thanks!
