We recently purchased a 2015 Avion Azure. There are 2 black switches in the bathroom on the outside wall. One controls the bathroom light. When the other is turned on we hear a wiring/pulsating sound that could be the sound of a pump. Any ideas what this might be? The previous owner could not tell us and the instruction manual is not very detailed. Am wondering if it's the macerator, but we were told that operated automatically. Thanks for any help.
