My 2007 MS had W/H switches inside and outside and winterizer tubing. Your 2011 unit should have the same locations at the main control centre and water closet. Make sure you don't accidentally leave the pump on while travelling a small red lite indicated on the switches. Two switches gas to electric one at the water heater unit and the other on the main control centre. Recommend you disengage the electric at the water heater if you do not intend to use electric. The tank coil will burn out if no water inside with electric engaged. There should be a cotter pin to lock out the switch at the tank switch..

Flush, clean the tank and inspect the anode rod two or three times a year, or you will be prematurely replacing the tank due to calcium deposit.

Do it yourself or pay the dealer $80.
