No hot water. On electric

[marv54]

I have a 2008 montana 5th wheel. I have hot water on propane but not electric. I checked and the reset buttons are not out. Any help

Could be that your element has burnt out. They aren't that expensive or hard to replace.

On most water heaters there is another on off switch on the outside in the lower left corner, it is possible that switch might be turned off.

Bad element first thing I would check

IF it is a Suburban water heater. As noted above, there is a black rocker switch on the water heater itself, outside, behind the water heater grill, at the lower left hand corner of the water heater. Make sure that switch is on. Some units have a second switch on the inside wall panel. My 2007 does not have the inside switch and I have to always go outside and actuate the outside switch.

If the switch(es) are on and it still does not work, then if you are comfortable troubleshooting electricity you can reference the Suburban water heater manual, page 9 for a schematic.

From previous posts about the same problem, the following failures have been found;
- bad switch on the water heater
- bad heating element (with at least one wire removed, it should read some small resistance across the element screws, not infinity)
- thermostat/hi limit cutout tripped
- bad thermostat/hi limit cutout
- loose wiring on the hot side
- loose wiring on the neutral side

Just make sure you are very careful of the shock hazard when troubleshooting with power on.

BTW... as a reminder, if you have the external switch only works with 110v.

If the switch has been on, then it does seem like it might be the electric element. If you didn't know about this switch and you've ever drained your hot water heater tank and didn't know about it, then the element may have burned out since it must have water in the tank to prevent this. Or the element just went bad. I've heard this happens.

Ironically, my dual power water heater is only working on electricity and the propane part is not working (probably the thermocouple). Since I am always connected to shore power, this has not been a problem and I haven't bothered to debug it yet.

I have been known to drain my hot water tank to clean it out, but I always turn off the electicity during this process. Then after refilling the water tank, I open ALL hot water taps, to ensure there's water flow (no air sputter at all!), THEN I turn on the electric switch.

Ours was never CONNECTED FROM THE FACTORY!
