Foxhunt, I would suggest reading the owners manual and reviewing the orientation video on Escape's website. There are also a ton of how-to videos for various systems on YouTube. Once you understand how a particular system works, troubleshooting is much easier. For example, you don't have to figure out where the hot water heater tank is located once you understand that the outside access panel is connected to it.
