Goodman GCH95 furnace condensation and or drainage issue

Hi DIY'ers, I've been trying to solve a problem with a Goodman furnace model gch950453bxac. I just bought the house and the furnace appears to be brand new or less than a year or two old. I don't have any info on who installed it otherwise I'd call them to come recheck their installation. The furnace would run for 10 to 15 minutes and shut off. By searching this forum I discovered that sometimes there is water buildup in the hose running to the pressure switches. Sure enough I found water in the hose. I spent quite a bit of time draining water from the right side pressure switch hose. The one on the left had only a drop or two. Well, I thought that would solve my problem but now I've got most of the water drained but the furnace now will only run for a few minutes then shutoff and water is no longer, or not nearly as much, in the hose. I do now hear water in the fan for the inducer motor and figure that can't be good. There is obviously water still inside the unit but can't figure out how to get the rest of it out. At this point I'm trying to figure out how the condensation pump and drain system within the furnace works because it does not seem to be doing it's job well, at all. The condensation pump itself seems to be fine because I have activated it a couple of times by pouring some of the drainoff into it. Can anyone point me to a manual that shows how drainage is supposed to work on this furnace? The manual I found with the furnace and what I have so far found online don't have any info on the drainage configuration. Any other suggestions? I will try and take some pictures to post if that will help.
