popping/clicking noise from hot water heater?

I haven't used the camper in quite a while as there has just been a lot going on lately and haven't had the chance. It sits in a campground plugged into city power. I keep the breakers on but the hot water switch turned off. I also turned the water off and ran all the water out of the pipes in early December to make sure water didn't sit and freeze. Today I had someone check in on the place for me and they sent me a video of a clicking/popping noise from the hot water heater. He said it didn't make that noise for very long. I want to say i've heard that noise in there before but it's been so long I can't remember.

Q: Is the breaker switch for the HWH on?
A: Yes

Q: Is the electrical switch for the HWH on?
A: No

    That was an initial thought but I'm not sure why it would be trying to fire up at all. Nothing would be triggering it as it's turned off. Unless I'm misunderstanding how the HWH operates.

    All it takes is for the switch to be off for a second or two with no water and the element will burn out and that is the noise he would have heard
    I am guessing like a few others have said that the element is burned out

    did you mean "all it takes is for the switch to be 'on' for a second or two with no water and the element will burn out?"


    Oops, my bad ! (another senior moment)
    I'll go back and change it

    Haha no worries. Was hoping it was a typo for my sake!
  • It could be that the gas switch was always off, but the electric switch was on. Or he has mice.
