Yes, you should be able to connect it directly to a drain instead of emptying the tank all the time.
On most condenser dryers like the WT46W560FG, there's an internal hose that normally feeds water into the container. That spiral hose you can feel at the back is probably the one. You usually need to open the rear panel, disconnect it from the reservoir, and attach a proper drain hose that runs to a standpipe or sink drain.
Before doing anything, check the installation manual for your exact model so you don't disconnect the wrong line.
