Cool, so there is the problem
And to re attach the small hose underneath, I would try one of the two tricks:
1) put half of the hose end on a 45 degree angle, and push the rest in so it joins.
Or, take the entire hose off by twisting it off the baseplate, try to attach the end with the plastic cuff first, then once it joins, it is easy to twist the hose onto the baseplate
