    Hello all! I’ve got a problem that hopefully someone here will have an answer for.

    Yesterday our old Raywall ER42D electric water heater developed a leak. So we set about replacing it with a new Whirlpool E2F40RD045V

    We hooked up the water and power exactly the same way as the old Raywall had been,
    made sure to fill the tank before turning on the electricity
    And waited the “few hours” for the Whirlpool to heat up the water…..but that never happened.
    We’ve tried resetting the thermostat, but this didn’t help.
    Use of a test light shows that the elements are intact.

    What could be keeping the heater from working?

    Thank you in advance for any assistance you might be able to provide.

    If you know how to use a voltmeter, you can test each bit of the water heater that might be malfunctioning, from the breaker down, by going to Tanklets, using the link at the top of the Tank topics index and reading the entry titled Electric Water Heater Issues. There is a troubleshooting walkthrough there that should help you pinpoint the problem. If you don’t know how to use a meter, better let a pro tackle it. Electric water heaters are dangerous.

    Hello: One simple place to start is with the circuit breakers. Sometimes they need to be reset by switching them off firmly and then back on. It sounds as though you may have no power to the heater. Also, check the wire nut connections at the junction box on top of the heater. Sometimes one doesn’t get a good connection.

    Remember to be slightly afraid of electricity. It’s dangerous and moves fast. Do get a meter and verify as Randy says.

    Yours, Larry


    Thank you both, Randy and Larry. Your help is truly appreciated.
    Using a voltmeter we found that while removing the old water heater we had broken one of the old wires meant to provide electricity to the heater. The new Whirlpool is now working quite well.

    *Problem resolved* 😀
