I have a Brute 2600 PSI pressure washer. The &S engine runs

Customer Question

I have a Brute 2600 PSI pressure washer. The B&S engine runs fine, but I get only nominal pressure from the pressure washer hose. The unit used to cycle (higher and lower RPM) when it was developing pressure, but now only idles. When I manually advance the throttle, it does not develop additional pressure. Any ideas?

Hi, my name is***** will be assisting you.

It sounds like the unloader valve inside the pump is stuck or hung and not working properly which will cause this issue.

If you will provide the model, type or spec and serial number I will see if the valve is offered as a replacement part. Sometimes they are not therefore you would have to replace the entire pump assembly in order to fix the issue.
