  • 110v water heater stopped heating

    Posted by Jim on October 18, 2018 at 7:08 pm

    had hot water last night for shower, but not this morning?

    Checked breaker panel, tuned off/on the switch in the bedroom panel.

    Over the weekend used the Wabasto for 12v heat and hot water, then switched back to 110v Monday. worked up until today.

    I did notice the water seemed much hotter last couple days.

    Is there a place to test voltage at the heaters ( two Atwood)

    note* the heaters were replaced couple years ago.

    If your water heaters are plumbed in to the engine cooling system for hot water heated from engine coolant (My Marathon was), it is possible that the engine coolant heated the water in the heaters beyond the heaters max thermostat setting and tripped the water heater electrical thermostat(s) off. If you remove the small access panel on the side of the water heater(s), you will see a reset button which can be pushed.

    Webasto should be around 160, but Rudy can verify.

    FWIW, I turn off the engine loop to the water heaters, better half almost got scalded once…
