Maybe you should check the hose. The problem is you can not remove the bottom without a special tool and the hose is unavailable. I am curious how EA6BDVR removed the bottom and then found the hose. I wound up braking the bottom of my coffee maker with the intent of gluing it but then could not find the hose.
I have a quick search and I found this good article in repairing coffee maker:
