HWH Jacks will not retract

[cruisergeek]

Thanks, that didn't help so I bled through a fitting on a hose connected to the manifold. I was able to get the 4th jack up and the control now reads "Travel". I then refilled the reservoir to the line to replace the lost fluid.

I cycled the bus through 2 raise/dump cycles, waited for it to settle completely on the bump stops and tried the HWH leveling system. It powers the unit up, but just makes a slight squealing noise but does not move the jacks.

Maybe related: On the LED readout box, all of the "LOCKED" lights are on when it is attempting to level. The squealing noise, I assume, is the pump trying to move oil but valves are closed.

Any ideas?
