If the gear "falls" uneven, it is air in the system which is difficult to get out.
(Just a pain to do., not hard)
How much extra 24 volt ext power?
The gear motor is a heavy draw, so turn off any and all electrics, not attached to the gear.
If the motor is old.. (which is probably, yeah.), the motor may be tired, and need a rebuild.
Do all of the locks "click" closed, and then the pump runs for another 20 seconds??
This system is troublefree- until it isn't.
Good luck.
