10E version uses DC to control electric and propane
Element might not be bad.....could be:
No DC from circuit board to the DC Relay
(yellow wire should have DC when Electric is selected and water is cold)
DC Relay could be bad
AC wires to/from that Relay could be melted
Element could be burnt out/shorted
DC Relay and Element are on backside of the WH Tank under the protective cover at bottom of tank
How you access depends on your RV....could be via inside a cabinet, removable panel, removable cabinet floor (removable means just stapled in place...pry it open) or even from underneath RV or panel in next compartment
Check for access directly behind where water heater is installed
Wiring..follow the DC


1 1/2" thin wall 6 point socket to remove element if bad
