Dishwasher drain hose?

Hey guys!

I just installed a new Bosch dishwasher last night and tried running a few cycles just to make sure it's working. It seems OK but is it normal for the drain hose to be full of water? I checked the dishwasher and it didn't seem to be flooded with water at the bottom. However, there was one time where I opened the door and there was water down there. But I just started and cancelled a cycle and it seemed to push the water out. However, it seems the drain hose is constantly full of water.

My setup is using an air gap.

Can someone let me know if this is normal... if not, what should I do to drain the water out and what's the best way to position the hose. BTW: I haven't yet run a full cycle - I was just trying to push some water through on a quick cycle and canceled about 5-10 mins in.

Will a full cycle push everything out?

Welcome to the forums! Out of curiosity how do you know there is water in the drain hose? The drain hose will need to move vertically to the air gap, then back down to the drain under the sink, either to the drain itself or to the disposer. If to a new disposer, make sure the knock out plug has been removed.
There will be some residual water left in the washer hose, and it is normal. Run it through a cycle and see what happens. Don't be afraid of it. Let us know how it goes.

Thanks Chandler! Just so there's no confusion, I'm talking about the corrugated hose directly from the dishwasher to the smaller airgap plug (not the rubber hose from the airgap to the disposal).

I know there's water in the dishwasher drain hose because I can see it in there - the hose is semi-translucent. Also, it does feel heavier as well. And I can feel the hot/warm water after the cycle is finished with the pump and flush.

As far as the disposer goes, I did make sure to knock out the plug - I'll double check one more time but I did make sure of this and retrieved the little slug (good thing the disposal was off! haha)

Anybody? Just ran a "quick cycle" but let it go overnight and there's still a bunch of water stuck in the drain hose.

If you ran a full cycle and it drained properly, why worry about it. Sort of like "does your light go out on the refrigerator when you close the door?" If it works, move on.

Water in the drain hose is normal. The drain pump can't push air through to clear it out and there's a valve that keeps it from running back into the dishwasher.
