HWH slides pulsing 2006 Adventurer 33V

[Rb05]

Both slides retract and expand with “pulses” rather than smooth operation?

The LR slide in our new to us 2005 Voyage has one side that pulses.

Is the oil level correct in the hydraulic reservoir? This should be checked with jacks retracted and slide room retracted. There is a dipstick on the bottom of the fill cap. If that is missing, oil level should be within ½" of top.
Never use hydraulic jack oil, only HWH oil or ATF as specified in your owners manual.

Thank you. Yes. The first thing I checked.

IMO that only leaves low voltage to the 12v motor, causing variable motor speed as the cause. Make sure you either have the engine running or the MH is connected to shore power, then try the system again to see if the "pulse' is still there.
This can lead to more possibilities, poor battery bank condition, poor ground of the leveling/room extension, poor connection on the positive side, air in the hyd. system, faulty/dirty valves in the manifold assembly, or even water in the oil-although that is unlikely as you would note the oil has a milky appearance after running the motor/pump. The oil should be clear and of consistent color.

I just looked it up in the HWH diagnostic manuals. that pulsing condition is either caused by low oil level or low battery power.
Always have the engine running or be on shore power when operating the slides or jacks.
