Water Heater Help?

[golf_bears]

Have an RV with Suburban SW12DE water heater. Water heater not working on electric but does work on LP.

The water heater “on switch” in the lower coat closet, near the breaker/fuse box, lights up when I flip it on, red light. Flipped the electric water heather breaker, as well as the GFCI off/on and all looks OK.

Took the V meter and tested for power at the electric heating element, no power appears to be going through the element. Confusing because the “on switch’s” red light lights up.

I’m suspecting I need a new heating element?

Are there any other on/off switches I’m not aware of?

I hit the reset switch/buttons, nothing changed, felt like the switch hadn’t tripped.

Any suggestions from anyone? All help appreciated, thanks in advance.
