I recently purchased my first MTH Premier steam engine. It is a Nickel Plate Berkshire from the 2020 catalog that just shipped. It is a beautiful engine that I love running. I am using the DCS WI-FI app to run it. I found the option in the app for the playable whistle and it works great, however I can’t get the whistle steam option to work. I filled up the separate whistle steam reservoir under the (sand?) dome and turned on the whistle steam option in the app. The playable whistle works, but no steaming whistle. Any idea what I’m doing wrong? Thanks in advance.
