Hi Singapore.

You have a lowering problem AC motors create electrical power the relationship between the two factors seem irrelevant.

Most units today with advanced electronics have a load holding solenoid or some way to secure the hydraulics in a fixed position - In your case up.

Read the schematic & determine first if you have an Electrical problem or a mechanical one.

If all your electrical is OK - then you need to find out why the pressure is being lost & the unit is lowering by itself.

More information is needed to proceed further.
