Having problems with your Karcher 2500 PSI Pressure Washer ?

New nozzle, plenty of water, but no pressure.

\015 My brother has the same model (2400 psi) and the same problem developed quickly after purchase. Has to be a Karcher manufacturing defect. Estimated repair cost is $200 - 250\015

Answers :

It is warrantied for 1 or 2 years. Low pressure could be due to the un-loader valve needing grease. If it is leaking it will not work properly. If it is stored somewhere cold during winter months the small parts inside will crack.

I have a Briggs & Stratton gas power washer. This is the 1st time this year that I have used it. I put in fresh gas, hooked up the water supply. The engine started and then quickly stopped. I had to release the water pressure in the hose before I could pull start the engine. The only way to keep the engine running is to hold down the spray nozzle trigger. Once that is released the pressure in the hose builds up and the engine stops.
