I have a 2008 Winnebago with the Kwikee Level Best system. Trust me, my story is to long to go into but I have been working with this problem since 2010 and I have the documentation to prove it. I even went to the Winnebago factory and after 10 days of working on it every day - left.
So here you go: If you don't have the manual there are steps to take to check the system and then there is MY fix.
As stated, with the jacks retracted check the oil level in the holding tank of the pump and make sure it is up to the level of the dip stick. You have to screw the dip stick back in to get the reading, or if you just stick it in you will be a little overfilled.
To "automatically" purge the air find a very level spot and extend the jacks to their fullest capability then release the "All-up." You may have to do this a couple times but this will purge the air out of the system. In my case this has never worked to the extent that the jacks do not fall down an inch or so.
I have had 3 jacks replace, the pump replace and the solenoids replaced and it still does the same thing.
My fix: In 2010 when this happened and W'bago could/did not fix it I put in a switch. I you are lazy you can just take the control panel out and unplug the 4 wire plug that is on the back of the control panel. This will stop the alarm and the light on the dash. If you follow the red wire off of that plug you will find a little module with spade connectors on it. I pulled the the red one off, bought a single throw single pole toggle switch, drilled a hole next to the control panel and installed the switch. the red wire goes to one side of the switch spade and I made another to go from the other side of the switch to the little module. Now, when I retract the jacks I throw the switch and there is no alarm or light. The jacks have never dropped down more than an inch or so and not all of them drop the same. I always see silver when checking them.
If you don't see silver and the jacks appear to be up but the alarm and light are on then it may be one of the 4 reed switches at the top of each jack. These are magnetic proximity switches wired in series. When the jacks are all up, pin 6 of the Level Best system should be shorted to ground. If not then each switch needs to be tested to find the open one.
Hope this helps and again, this is for my 2008 with the Kwikee Level Best system.
Edited: I just re-read your post and 1/4 to 1/2 way down is way to much. If the oil is up to the full mark and this has happened there is a real problem that should be looked at by a pro.
