Check the perimeter of the rubber seal arounf the slide after sitting for a day or so;  if you see daylight chances are the aux pump cannot keep up with the loss of air from the bladder seal.  Try spraying some soapy solution around the slide perimeter and view for the resulting bubbles.  If in fact it turns out to be a hole in the bladder, I tried various ways, some with the help of the forum. no fixing that bladder as the cut was in the area that flexed with each inflate and deflate cycle. 
Decision made a few months ago to take long trip to Moscow IA from Atlanta;  they did a great job, cost ~$3,000 + travel.  They replaced the rubber seal and also included a reman manifold which was required to service the new seal inflation technology. 
Recommend you call HWH to seek their analysis of the problem;  very nice people, know their stuff.  Good luck.

Fred, when you turn the HWH Slide key on air passes through the slide air manifold to suck air out of the bladder.  When the slide is done moving and you turn the slide key off you may hear some air for a minute or two as the bladder reinflates.

If the key is left on the compressor will eventually turn on.. put a pic up of the area you think the issue is.. block = manifold?

Hi Fred; I have the old manifold which HWH said was good.  They said that I needed to replace it as "the new air
seal required a replacement vacuum manifold, the new vacuum manifold has a
check valve in it to hold the air seal down when it vacuums it down,
because a few years ago HWH changed the design of the air seal. The old
one is molded in the flat position and the new one is molded in the
inflated position and if it goes to ambient pressure it will rub on the
room as it goes in and out and could scratch the room."

You're welcome to my old manifold if you feel it will solve the problem.  According to HWH,  if you have the old style air seal my old manifold will work out just fine.  Let me know where to ship the unit; it's pretty heavy thus not sure what the shipping costs to you would be.
