    It's happened to me.........

    .......also, Scott. Not many, but a few. Turn the speed up and it goes, then set it back to low and everything is fine. Pump? Debris? Lack of starting torque?

    old ones

    I removed 4 three speeds about 10 years ago. They were put in either in 1960 or 1972, no later than that. The instruction manual was still there. In it, Grundfos was admitting that if on low speed and it hadn't ran for awile it may not turn on. It then said to up the speed to get it going. I could't believe this disclousure. Nowadays that would be seen as self incrimination. A change, I think in the capacitor was their cure. But I guess sometimes- Not!

    Funny how you are the only one.

    I never accept or believe that answer. You may want to open them up and check for rubbing of the impeller or a bit of debris in the housing.

    Not newer ones

    The old ones stuck all the time.
    They have added the "jigulator" in the control box for some time now to solve that.

    yes, and i've switched brands because of the switch.

    sometimes the switch's little plastic junky ''fingers'' don't seem to grab the high quality plastic stem well..i think my dog could come up with a better design..

    yup

     its frustrating when its  a pump i sold in'06 ( I like the customer and I take these issues personal)  then low speed quit so i click it to medium speed  so when pump failed in '08 I replaced it with a taco . I seen other grundfos pumps do it too 40-80  down to 15-58 . currently I am using wilo so far OK.

    Thanks

    Yes I am talking about the newer 15-58 ... its a shame bu after getting call backs for the low speed not starting and being told no one else has mentioned it ....... I now use Wilo.
    I had  a brand new GB that got a call for not heat and the priority Grundfos was out on speed one.
