Question and Answers

Q:

My pressure pump, model DT2400CS, stalls when I release the lever. It only runs on initial start up.

A:

More than likely the unloader valve in the pump needs cleaning or replacing. The unloader valve is inside the pump body. If you have a pressure adjustment knob, the unloader valve is underneath it.

Most times there is some buildup inside the pump body that stops the piston on the unloader valve from sliding.

We don't have any parts information and no repair images for the pump.

I am sending you an image that shows a typical pressure washer pump and the location of the unloader valve.
