Suburban SW6DE water heater

i have a problem with my water heater. It started when the heater would fire up, while it was working it would still keep clicking and sparking. then it would shut down, it would do this 3 times and then stop. If i had shore power the heater would work fine on electric.

So i think maybe the flame sensor is bad, so i bought a new one and installed it yesterday, again it fires up 3 times and shuts down.

I need help! What could i try?

  • That is something I can try, it could be the flame is not perfect. I do get main flame though it just doesnt stay on.

    if it engulfs the electrode correctly and all wires are good, do you think the board would be bad?

    The spark electrode is also used as means of flame proofing......the main flame must engulf the electrode to produce a milivolt signal to circuit board that shows main flame is lit.

    No signal and circuit board will attempt to lite 3 times and then lockout.

    IF you have main flame then adjust flame so it engulfs electrode.
    Also check that ground wires are clean & tight.

    IF you do NOT get main flame then check for obstructions in burner tube, orifice and for power at gas valve solenoid(s) during sparking. Power is only at gas valve solenoid for 6-8 seconds during lighting attempt(s).

    Otherwise.....circuit board may be faulty

  • Batteries are fine, the heater works on propane or electric. the electric element requires shore power.

    I would start by checking your battery.
    If it works fine on shore power, but shuts down on battery, you may have a bad battery.

  • Yes the flame goes out

    Is it lighting and the flame continues to burn? If so it may just be continuing the ignition cycle of 3 three attempts. If it is working I wouldn't worry about it.
    When you say "shuts down" do you mean the flame goes out?
