Lately the dishwasher will sometimes fill with water, start,
make a lot more noise than usual, then empty within a minute.
It then refills and when it starts again, it operates normally.

Is this a problem? Has something failed or is something about
to fail?

Sounds like the controls have added a pre-wash rinse cycle. Or, it is
part of the fill and checking system for the amount of dirt. Our
machine partly fills, turns on for a short time, then finishes the
fill and continues. I'm told there are sensors that check the water
to see how dirty the dishes are and it does something to the cycle
time.

Are you running on a different cycle than you used in the past?
