High Pressure Pump Problem

[APW]

Of course I am out of State and my PDQ starts acting up. The high Pressure pump will only run about 2 or 3 seconds. Enough to build up high pressure and then shuts off. I am thinking there's something going on with the 25 horsepower motor. Has anyone ever experienced this and have any idea?

How does it shut off- trip an overload?

Is your regulator/unloader working properly?
Do you have a HP solenoid valve that might be stuck closed?

What does your error report say? Overload, low water sensor, water pressure sensor. Could be multiple things

Greg I think you are spot on with the valve not opening on the Undercarriage causing the overload to trip. I ordered a rebuild kit and hopefully it will be in today.
