Electric element is installed in the back of WH Tank under the black protective cover at bottom.
Also inside that cover is the 12V DC relay with 120V AC wiring from relay to element
Element is a 120V AC 1400W element that screws into tank and is over 10" in length
Need a thin walled 6 point 1 1/2" socket (or element wrench) to R/R element
PITA when you have direct access.......
Some MH Mfgs have unique access .....side panel, underneath panel etc
Some you have to remove water heater.
