    Dolphin m4 problem

    Hi.

    I have a dolphin m4. The controller turns on, lights up etc, but when I press the button to move the cleaner nothing happens. I assume the motor is blown?

    How do I diagnose the problem?

    Thanks

    Re: Dolphin m4 problem

    How long have you had it? Does the place you bought it have the expertise to diagnose the issue? Send Maytronics an e mail and ask them for their manufacturer recommendation.

    I bought an S-1 and I think it is fantastic, even when my pool looks very clean and I let it do a 2 hr cycle the filter frames come out black and catch so much you can see. I swear by it. When I bought mine they had a promotion where you get an extra fine filter basket in addition to the just the basic screen. I also like that it is self contained and all that it catches never enters your main filter.

    let us know how you make out with this.

    I know of another S-1 problem where the machine will not climb the walls but have no resolution yet.

    Re: Dolphin m4 problem

    I've had the cleaner three years I think. It gave out at the end of last season.

    I bought it on line, so no real help there.

    One of the reasons I bought this particular model was because I believed it could be maintained by the user. I.e. Parts could be swapped out etc.

    I'm surprised no one here has had to diagnose one of these or replace the motor etc. 😕

    My first guess is always the power supply. Do you know anyone with a similar unit that you can borrow?

    This would be my first thought and step to diagnose.

    There probably are people here with that knowledge. Either give them some time to notice the thread and respond or do a search for previous threads in the upper right corner.

    Re: Dolphin m4 problem

    Have you tried pressing the reset button? That always fixes mine when it occasionally decides to just sit there when I press the start button.

    Re: Dolphin m4 problem

    Thank you all for the responses.

    yes, tried pressing the reset button.



    This is what happens:

    If the cleaner is not plugged into the power supply/controller and I turn on the controller, the on switch lights up and the three 123 lights blink for a few seconds, then just the on switch is lit.

    If the cleaner is plugged in then the on switch lights up momentarily (maybe a second) and then goes off.


    wrt the cleaner.

    The impeller at the top turns, though will not freely spin (I would not expect it to).
    The tracks will turn, again not freely (I would not expect them to).

    So, it appears there is nothing jamming either the tracks or the impeller.

    Other thoughts?
