    Default There is no rhyme or reason to my Ehiem

    Can't figure this one out. My ehiem was flowing water
    one minute and the next minute it's not working.
    I have created the syphon and filled up the canister
    and have the flow go out the output. I plugged the
    unit on and it's not flowing water. I have cleared
    all the passages. And tried again. But the pump
    is not flowing water. I see the propeller turning,
    but I don't know why it's not sucking in the water.
    Does this mean it's kaput? Why would the
    pump not be flowing water correctly?

    Thanks,
    Jeff

    Have you primed it? I am not sure of your model or set up, but most canisters need a prime and have a little lever to crank to get it going and flowing, try that.

    I agree with the others. You could have an airlock. When you say you filled the canister did you push the primer button until you could see the canister filling on it's own or did you manually fill canister.

    Occasionally I get an air lock and can't clear it using the primer button on my again pro 4+

    When worse comes to worse I suck the end of the return tube/spray bar and usually it will create enough siphon to purge the air in the intake line
