200 Series HWH leveling jack Pump won't stop

Hi All, I have the joystick operated kickdown leveling jacks.

I extended the jacks and the pump cycled as expected. But this time, the pump did not stop. Not sure what happened but even though I returned the joystick to resting position, the pump continued to cycle.

I had to disconnect the chassis battery to stop the power to the pump. I also dumped the jacks.

After digging around and checking my fluid reservoir, I realized I was terribly low on fluid.

Have I broken something in the system by operating them with insufficient fluid levels? Is anyone familiar with the symptoms I am facing of the pump continuing to cycle?

  • When you move your joy stick, it sends a 12 volt signal to the relay mounted on or near the pump motor. Either the signal is staying on or the relay is stuck.
