My 2011 Georgetown 327DS had the same problem when I received it. The water heater is attached to the front panel and there were two 1x2 boards under the bottom edges of the heater to support it. Unfortunately, there's two problems with this. first, the heater is surrounded by a styrofoam blanket and the edge of the 1x2 would compress the styrofoam causing the water heater to tilt, popping out the front panel. Second, the plastic compartment bottom will bend under the weight of the water heater, causing the same problem.
My dealer fixed the problem by installing a support board that goes all the way to the back of the compartment under the heater. Now, with the entire bottom of the heater resting on a support, it doesn't pop out the front panel any more.
