Dishes seem to be cleaning, but I figure something must not be working correctly. This dishwasher is relatively quiet while running, but I've noticed a high pitch sound between cycles. Nothing is happening when the sound is there.

The dishwasher does complete it's cycle normally. I tried searching but nothing came up for this model. Anyone know what this could be?
