Not sure of your layout, but you might check behind the panel in the storage area. I have a Kingston and found the water filter mounted behind the panel with the water connection. I had to remove 4 screws to remove the side panel to gain access to the filter. If it is there, make sure the power inverter is not mounted below it. I found the inverter mounted below the water filter in my Kingston and relocated it right away. Water and electricity don't mix too well.
