Having problems with your Pressure Washers ?

Pulsing and lost pressure

\015 Please can you help. I have a Karcher K3.91 about 2 years old, it now pulses when trigger is released and has hardly any pressure. I have taken it apart and checked the release valve and o-ring both seem fine. When it pulses you can see the pressure is released into the garden hose pipe because it moves, what do you suggest\015

My Karcher 411A seems to have lost pressure. Behaviour is this, when you press the water release on the spray gun you get 100% pressure for like 10 seconds and then it seems to dwindle down to 30-40% of its total pressure. When the pressure cuts down I can hear more noise coming from the gun sprayer aswell. So not sure if the problem is in the gun or the main pump unit ?

No pressure Gas powered pump is a radial type from DeVilbiss. There is very low pressure, although there is some pulsing from the pumping action. There are no leaks and the supply pressure is good. Pump pistons are in good condition. They seem to be pumping when I had it disassembled and operated by hand. I suspect it is something in the bypass or unloader. Or it may be in the ''easy start'' assembly which I assume reduces backpressure on the pump when starting the engine. Pump has a temperatu
