    Welcome to TFP!

    After the pump stopped working, did you check to see if it had tripped to circuit breaker or a GFCI associated with the pump? Will the pump turn on and prime if you put the multiport valve back to Filter?

    How long did you leave it making a humming noise

    First check to make sure you have power at the outlet (or that there is power to the feed, if your pump is hard wired)

    Next, check to make sure that a on-pump circuit breaker did to trip.

    Once you have done that, check to see if the pump is seized (can you spin it manually)
